EU Cosmetic Regulation (EC) No 1223/2009 defines strict rules for cosmetic products sold in the European Union, focusing on consumer safety through ingredient controls. The regulation includes:
- Annex II: Over 1,700 banned substances, including carcinogens and toxins.
- Annex III: ~370–380 restricted substances with specific usage conditions like concentration limits, product categories, and labeling requirements.
- Annexes IV–VI: Approved lists for colorants, preservatives, and UV filters.
This guide highlights 10 restricted ingredients under Annex III, explaining their limits, applications, and compliance requirements for U.S. brands exporting to the EU.
- 1. Formaldehyde and Releasers: Capped at 0.2% in most cosmetics; must be labeled if ≥0.05%.
- 2. Parabens: Short-chain (e.g., methylparaben) allowed up to 0.4%; longer-chain (e.g., butylparaben) restricted to 0.14% and banned in baby products.
- 3. Triclosan/Triclocarban: Fully banned due to health and environmental risks.
- 4. Salicylic Acid: Limited to 2% in rinse-off and 0.5% in leave-on products.
- 5. Hydroquinone: Prohibited in all cosmetics; alternatives like niacinamide are recommended.
- 6. Fragrance Allergens: 26 allergens, such as limonene, must be labeled if exceeding 0.001% (leave-on) or 0.01% (rinse-off).
- 7. Resorcinol: Restricted to 1–2% in hair dyes; must include allergy warnings.
- 8. Nanomaterials: Specific bans (e.g., nano gold, silver) and limits for hydroxyapatite in toothpaste (10%) and mouthwash (0.465%).
- 9. UV Filters: Stricter limits for octocrylene, homosalate, and benzophenone-3; aerosol use restricted.
- 10. Heavy Metals: Lead, arsenic, and cadmium must remain below trace limits (e.g., Pb <10 mg/kg).
Key Takeaways:
- Non-compliance can result in recalls, fines, or market bans.
- Labels must include mandatory warnings and INCI names.
- U.S. brands must reformulate products with banned or restricted ingredients and maintain a Product Information File (PIF).
Partnering with reliable suppliers ensures ingredient quality, safety documentation, and compliance with evolving EU standards.
Your roadmap to EU & UK cosmetics compliance: Understanding Regulation (EC) No 1223/2009
1. Formaldehyde and Formaldehyde-Releasing Preservatives
Formaldehyde holds a unique position under EU cosmetics law. Unlike substances banned outright in Annex II, its use is tightly controlled under Annex III, entry 11 of Regulation (EC) No 1223/2009. This means formaldehyde can serve as a preservative, but only within strict concentration limits and with specific labeling requirements. Additionally, formaldehyde is classified as a CMR 1B substance (carcinogenic, mutagenic, or toxic for reproduction) under the EU’s CLP Regulation, warranting close regulatory oversight.
The same rules apply to formaldehyde-releasing preservatives, such as DMDM hydantoin, imidazolidinyl urea, diazolidinyl urea, quaternium-15, bronopol, and sodium hydroxymethylglycinate. These ingredients don’t contain free formaldehyde initially but release it over time to provide antimicrobial benefits. The EU treats the formaldehyde they release with the same caution as free formaldehyde added directly to products.
Maximum Concentration Limits
The EU has set strict limits on free formaldehyde content in cosmetics. For most products, the maximum allowable concentration is 0.2% (2,000 ppm), regardless of whether the formaldehyde is added directly or released from preservatives. For example, if you include 0.3% DMDM hydantoin in a facial moisturizer, you must ensure that the free formaldehyde content does not exceed 0.2%.
Oral hygiene products, such as mouthwashes and toothpastes, are subject to a stricter limit of 0.1% (1,000 ppm) due to the higher risk of ingestion. Any oral care product using formaldehyde or its releasers must meet this lower threshold in its final formulation.
When multiple formaldehyde-releasing preservatives are used in a formula, their cumulative contribution must be calculated to ensure compliance. For instance, a body lotion containing 0.25% DMDM hydantoin and 0.1% quaternium-15 would require stability testing to confirm that the total free formaldehyde stays below 0.2%.
Product Category Considerations
Annex III does not differentiate formaldehyde limits based on whether a product is rinse-off or leave-on. The 0.2% limit applies universally to all non-oral cosmetics, while the 0.1% limit remains specific to oral hygiene products.
However, formulators often avoid using formaldehyde and its releasers in certain products. Aerosol sprays and items for children, for example, are typically designed without these ingredients due to concerns about inhalation and sensitization risks. A spray deodorant or a children’s shampoo might be formulated without formaldehyde releasers, even though the general regulatory cap is 0.2%.
Mandatory Labeling Requirements
If a product contains formaldehyde at or above 0.05% (500 ppm), the label must include the phrase "contains formaldehyde". For formaldehyde-releasing preservatives, the EU requires the words "releases formaldehyde" to appear directly after the INCI name on the ingredient list. For example, "DMDM hydantoin (releases formaldehyde)" must be clearly stated.
Failing to include these mandatory label statements can lead to regulatory actions such as product recalls or customs rejections, even if the free formaldehyde levels are within the legal limits. These labeling rules, combined with concentration controls, are designed to ensure full compliance.
Purity and Impurity Standards
Beyond concentration limits, manufacturers must ensure that raw materials meet safety and quality standards, often guided by pharmacopoeial monographs like those in the Ph. Eur. or USP. Annex III also sets impurity thresholds for contaminants such as heavy metals and 1,4-dioxane. When sourcing formaldehyde or its releasers, it’s essential to obtain certificates of analysis confirming low residual formaldehyde, minimal heavy metals, and the absence of other harmful impurities.
For technical-grade and compendial-grade preservatives that meet these stringent standards, consider working with Allan Chemical Corporation. Their products come with documented low impurity levels and robust quality systems, simplifying compliance with Annex III requirements for your Product Information File (PIF).
To ensure regulatory compliance, document all contributions of formaldehyde in your formulations. This involves identifying all formaldehyde-releasing ingredients, estimating the formaldehyde released by each, calculating the total free formaldehyde, conducting stability tests to measure actual levels over time, and recording all findings in the PIF as part of the safety assessment.
As of the latest amendments to Regulation (EC) No 1223/2009, including the March 14, 2024 revision of Annexes II and III, the formaldehyde limits remain unchanged at 0.2% for cosmetics and 0.1% for oral hygiene products. However, given formaldehyde’s classification as a CMR substance and allergen, future updates could introduce stricter limits or additional labeling requirements. Stay informed by regularly checking the European Commission‘s Cosmetics Legislation page and the CosIng database.

2. Parabens with Chain Length Restrictions
Parabens are governed by Regulation (EC) No 1223/2009, which categorizes them based on chain length: short-chain parabens (methylparaben and ethylparaben) and longer-chain parabens (propylparaben, butylparaben, and their branched variants). This classification reflects toxicological evidence linking longer-chain parabens to greater endocrine-disrupting concerns, particularly for infants and young children.
Under Annex V (permitted preservatives) and Annex III (restricted substances), the EU allows parabens under strict concentration and use limitations. However, certain longer-chain parabens – including isopropylparaben, isobutylparaben, phenylparaben, benzylparaben, and pentylparaben – are prohibited under Annex II due to insufficient safety data, especially regarding endocrine activity as reviewed by the Scientific Committee on Consumer Safety (SCCS). Below, we outline the concentration limits and product-specific restrictions for parabens.
Maximum Concentration Limits
For methylparaben and ethylparaben, the EU permits concentrations of up to 0.4% (as acid) per paraben in finished products. When multiple parabens are combined, their total concentration must not exceed 0.8% (as acid). For instance, a facial serum containing 0.3% methylparaben and 0.2% ethylparaben meets both the individual and combined limits (0.5% total).
Propylparaben and butylparaben face stricter limits, with a maximum of 0.14% (as acid) each when used individually. These also contribute to the overall 0.8% paraben cap when combined with other parabens. These stricter thresholds stem from SCCS findings that higher concentrations may pose endocrine risks, especially with prolonged skin exposure.
Remember to account for molecular weight differences when converting salt forms to acid values. Accurate conversion is critical for compliance and must be documented in your Product Information File (PIF) to ensure alignment with regulatory audits and market checks.
Product Category Restrictions
The EU imposes additional restrictions based on product type and target users. For example, propylparaben and butylparaben cannot be used in leave-on products for the diaper area of children under 3 years old. This restriction addresses heightened absorption risks due to compromised skin barriers and occlusive diaper conditions, which could increase systemic exposure.
For other categories, such as adult skincare, hair care, or rinse-off products, these parabens are allowed within the 0.14% individual and 0.8% total limits, provided safety assessments support their inclusion. For example, a body wash containing 0.1% propylparaben or a hand cream with the same concentration for adults would comply. However, many brands have voluntarily removed these longer-chain parabens from all baby and children’s products, even outside diaper-area applications, due to consumer demand and the popularity of "paraben-free" claims.
The general concentration limits (0.4% for methylparaben and ethylparaben, 0.14% for propylparaben and butylparaben, and 0.8% total) apply to both rinse-off and leave-on products, except for the diaper-area restriction. While rinse-off products inherently involve shorter contact times, the EU does not allow higher limits for these formulations. Many formulators build additional safety margins into rinse-off products, especially for facial or sensitive-skin applications.
Mandatory Labeling Requirements
All parabens in EU cosmetics must be listed on the ingredient label using their INCI (International Nomenclature of Cosmetic Ingredients) names, such as Methylparaben, Ethylparaben, Propylparaben, and Butylparaben, in descending order of weight. Unlike formaldehyde, parabens do not require extra warning statements like "contains parabens" as long as concentrations comply with Annex III and Annex V limits.
If a product is labeled "paraben-free", it must not contain any restricted parabens above trace levels. This ensures accurate consumer information and prevents misleading claims. For products sold in multiple EU countries, the ingredient list and other required label elements (e.g., responsible person, batch number, warnings) must be provided in the official language(s) of each country where the product is sold.
Purity and Impurity Thresholds
Although Annex III does not specify exact purity or impurity thresholds for parabens, the EU Cosmetics Regulation assumes compliance with general safety and quality standards. Parabens should meet pharmacopoeial standards (e.g., Ph. Eur., USP) or technical-grade criteria to ensure safety and performance. Impurities, such as residual solvents or related substances like 4-hydroxybenzoic acid, must be minimized under good manufacturing practice (GMP).
Residual solvents should adhere to ICH Q3C toxicity limits. Heavy metal impurities – including lead, arsenic, cadmium, and mercury – must remain below general cosmetic limits (e.g., lead under 10 mg/kg, arsenic under 2 mg/kg, cadmium under 5 mg/kg, and mercury under 1 mg/kg). Certificates of analysis (CoA) from raw material suppliers should confirm these impurity levels, and batch records must verify that finished products meet safety standards.
Document each paraben’s concentration, stability over the product’s shelf life, and compliance with Annex III restrictions. This includes identifying each paraben by its INCI name and CAS number, calculating the acid-based concentration, summing the total concentration, and confirming compliance through stability testing. All findings should be recorded in the PIF to ensure regulatory alignment.

3. Triclosan and Triclocarban
Triclosan (CAS 3380-34-5) and triclocarban (CAS 101-20-2) have been banned in EU cosmetics due to concerns over their potential risks, including endocrine disruption, antimicrobial resistance, bioaccumulation, and harm to aquatic ecosystems. Triclosan was prohibited in 2017, while triclocarban, classified as a CMR 1B substance (carcinogenic, mutagenic, or toxic for reproduction), has been banned since September 1, 2023, under Regulation (EU) 2022/1181. As a result, any cosmetic product containing these substances cannot be sold in the EU or EEA markets after their respective ban dates.
For U.S. brands and formulators exporting to the EU, this means that existing formulations with triclosan or triclocarban must be reformulated using alternative preservation systems. Even if these ingredients are still allowed in some U.S. applications, they are completely prohibited under EU law. Below is an overview of the regulatory framework, compliance requirements, and considerations for replacing these banned antimicrobials.
Maximum Concentration Limits
The EU has adopted a strict zero-tolerance policy for triclosan and triclocarban in cosmetics. Previously allowed concentration limits no longer apply, and any detectable presence of these substances constitutes a regulatory violation under Annex II. This approach reflects concerns over cumulative exposure and applies across all cosmetic categories.
In contrast, the U.S. Food and Drug Administration (FDA) banned triclosan only in specific over-the-counter antiseptic washes in 2016, leaving its use in other products less restricted.
Product Category Restrictions
Both triclosan and triclocarban are banned from all cosmetic product categories in the EU. Formulators targeting the EU market must replace these substances with EU-approved preservatives.
Products that claim antimicrobial or antibacterial properties may fall under the Biocidal Products Regulation, which requires a separate and more stringent authorization process. For instance, a liquid hand soap marketed as a cosmetic cleanser in the U.S. must be reformulated with EU-approved preservatives – such as phenoxyethanol, organic acids, or certain parabens within permitted limits – before being exported to the EU.
Mandatory Labeling Requirements
To comply with EU regulations, cosmetic products must completely exclude triclosan and triclocarban from their formulations and ingredient lists. Any product listing these substances is considered non-compliant and subject to regulatory action. Label audits and regulatory checks are now essential for U.S. brands exporting to the EU, ensuring that banned ingredients are entirely absent.
Purity and Impurity Standards for Alternatives
Although triclosan and triclocarban are banned, it’s crucial to evaluate the purity and impurity levels of alternative ingredients. Replacement preservatives must meet stringent purity standards, with impurities like heavy metals and residual solvents kept within acceptable limits, as outlined in ICH Q3C guidelines.
Suppliers such as Allan Chemical Corporation provide detailed documentation to support compliance with these requirements. For U.S. formulators transitioning to EU-approved preservatives, ensuring the new ingredients meet these high standards is critical. Allan Chemical Corporation offers technical- and compendial-grade ingredients to help manufacturers smoothly shift away from banned antimicrobials while validating alternative preservation systems.
4. Salicylic Acid and Salicylates
Salicylic acid (CAS 69-72-7) is a popular ingredient in cosmetics, especially for its exfoliating and anti-acne properties. However, its use in the European Union (EU) is tightly regulated under EU Regulation (EC) No 1223/2009. Listed in Annex III as a restricted substance, salicylic acid can only be used within specific concentration limits, pH levels, and product categories. U.S. brands exporting to the EU must adapt their formulations to align with these requirements. Unlike in the U.S., where products with salicylic acid may be classified as drugs, the EU treats them as cosmetics. This distinction means they must meet different safety, labeling, and marketing standards.
The biggest hurdle for formulators lies in adjusting concentrations based on whether the product is rinsed off or left on the skin, while also adhering to pH restrictions. Additionally, products must include any mandatory warnings and meet strict purity standards to avoid contamination. Below, we’ll outline the regulatory considerations for salicylic acid and salicylates in EU cosmetics.
Maximum Concentration Limits
Annex III specifies the following limits for salicylic acid in EU cosmetics:
- Rinse-off products: Up to 2.0% (w/w) with a pH of 3.5 or higher.
- Leave-on products: Up to 0.5% (w/w) with a pH of 3.5 or higher.
- Oral care products: Up to 0.1% (w/w).
For example, a U.S. acne cleanser formulated with 2% salicylic acid can often be sold in the EU without changes, provided it meets the pH requirement and is labeled as a rinse-off product. However, a leave-on serum containing 2% salicylic acid would need to be reformulated to 0.5% or less. In such cases, additional testing may be needed to ensure the lower concentration still provides effective results.
These concentration limits vary depending on the product type, requiring formulators to make precise adjustments.
Product Category Restrictions
Products containing salicylic acid are generally prohibited for children under 3 years old, except for certain rinse-off formats where exposure is minimal and explicitly permitted under Annex III. This is particularly relevant for items like baby shampoos or diaper creams. Formulators must also consider the size of the application area – products like body lotions, which cover larger areas, often require more conservative concentrations compared to spot treatments or acne patches. Additional scrutiny may apply to aerosol or powder formats due to inhalation risks.
When combining salicylic acid with other active ingredients such as alpha-hydroxy acids (AHAs), retinoids, or fragrance allergens, formulators must carefully evaluate the potential for irritation or sensitization. The Cosmetic Product Safety Report (CPSR) may recommend using salicylic acid at the lower end of its allowable range, adjusting the pH, or limiting use to rinse-off formats to ensure safety and efficacy.
Mandatory Labeling Requirements
EU labeling laws, outlined in Article 19 of Regulation (EC) No 1223/2009, are strict. Labels must include:
- The INCI (International Nomenclature of Cosmetic Ingredients) list.
- Product content and the PAO (Period After Opening) symbol.
- Warnings, such as "Not for children under 3 years."
- Batch numbers.
- Contact details of the EU Responsible Person.
For products with salicylic acid, labels must clearly display any required warnings in the local language. Common warnings include avoiding contact with eyes and mucous membranes and discontinuing use if irritation occurs. Additionally, claims like "treats" or "cures acne" are prohibited, as they suggest medicinal properties. Brands must use cosmetic-appropriate language, such as "helps reduce blemishes."
For U.S. brands, ensuring compliance involves translating and auditing labels to meet EU standards. This process helps avoid delays or penalties once products enter the market.
Purity and Impurity Standards
Beyond concentration limits, salicylic acid used in EU cosmetics must meet rigorous purity standards. Heavy metals like lead, cadmium, and arsenic must be kept below specific thresholds (e.g., Pb < 10 mg/kg, As < 2 mg/kg, Cd < 5 mg/kg). Residual phenol and solvents, byproducts of salicylic acid synthesis, must also comply with ICH Q3C guidelines.
Manufacturers should obtain Certificates of Analysis (CoAs) for each batch, documenting assay results, impurity profiles, and heavy-metal testing. This documentation is a critical component of the Product Information File (PIF) and supports the safety assessments required by EU law. For U.S. companies, robust supplier qualification programs, regular quality control testing, and complete traceability of raw materials are essential for compliance.
Suppliers like Allan Chemical Corporation provide technical-grade and compendial-grade salicylic acid (USP, FCC, ACS, NF) with verified purity and impurity limits, along with detailed documentation to support EU regulatory requirements. Reliable sourcing ensures a smoother transition from U.S. formulations to EU-compliant cosmetics.

5. Hydroquinone and Skin-Lightening Agents
Hydroquinone (CAS 123-31-9) is a skin-lightening ingredient that has sparked significant debate. In the European Union (EU), it is completely banned from cosmetic products under Regulation (EC) No 1223/2009. Listed in Annex II as a prohibited substance, hydroquinone cannot be intentionally included in any cosmetics sold within the EU. This decision was made based on safety concerns raised by the Scientific Committee on Consumer Safety (SCCS), including risks such as skin irritation, contact dermatitis, and exogenous ochronosis (a condition causing blue-black skin discoloration). U.S. brands that use hydroquinone in their formulations must reformulate their products with alternative ingredients to meet EU standards before entering the market.
Maximum Concentration Limits
EU regulations are clear: hydroquinone is not allowed in any concentration for cosmetic use. The only exception is its use in certain professional nail products under strict conditions, but this does not apply to skin care or skin-lightening products. Whether it’s a face cream, serum, spot treatment, or body lotion, no cosmetic product sold in the EU can include hydroquinone as an active ingredient. Brands in the U.S. that rely on hydroquinone for products aimed at brightening skin or reducing spots must completely reformulate with EU-approved alternatives.
Product Category Restrictions
Hydroquinone is banned across all cosmetic categories in the EU, without exception for rinse-off or leave-on products. Skin-lightening creams containing hydroquinone are often seized or recalled when discovered in the EU market, demonstrating the strict enforcement of these rules by national authorities and through RAPEX (Safety Gate). U.S. exporters must thoroughly verify their products’ compliance with these regulations before shipping.
To meet EU standards, brands must reformulate with approved alternatives like niacinamide, kojic acid, azelaic acid, vitamin C derivatives, or specific plant extracts. For example, niacinamide (vitamin B3) is allowed at concentrations of 2% to 5% in leave-on products, while kojic acid is permitted up to 1% under Annex III (entry 155). Alpha-arbutin and beta-arbutin can also be used at safe levels of 1% to 2% in leave-on formulations, provided they meet general safety requirements. These ingredients are typically marketed with terms like "radiance-enhancing" or "tone-evening" rather than "bleaching" or "whitening", aligning with EU labeling rules.
Mandatory Labeling Requirements
Cosmetic labels in the EU must adhere to strict guidelines. They must list ingredients in descending order using INCI (International Nomenclature of Cosmetic Ingredients), include details of the EU Responsible Person, state the nominal content, provide expiry information (either an expiry date or PAO symbol), display the batch number, and include any required warnings. Avoid claims like "treats melasma", "treats hyperpigmentation", or "bleaches skin", as these could classify the product as medicinal. Instead, use phrases such as "helps reduce the appearance of dark spots", "brightens skin tone", or "evens complexion." If a product contains any of the 26 recognized fragrance allergens above the threshold (0.01% for rinse-off products or 0.001% for leave-on products), they must also be explicitly listed on the label.
Purity and Impurity Thresholds
Since hydroquinone is banned as an intentional ingredient in EU cosmetics, there are no official purity specifications for its use. However, if hydroquinone appears as an impurity due to ingredient degradation, its level must be minimized to the lowest technically possible amount. For approved skin-lightening agents like kojic acid, arbutin, or niacinamide, manufacturers must ensure high purity and control impurities such as heavy metals and residual solvents. For example, 1,4-dioxane levels must be kept below 30 mg/kg to comply with EU safety standards.
Using high-purity raw materials from trusted suppliers is essential. Certificates of Analysis (CoAs) should document assay results, impurity profiles, and heavy-metal testing. These documents are a crucial part of the Product Information File (PIF) required for safety assessments under EU law. For U.S. companies transitioning to EU-compliant formulations, robust supplier qualification programs, regular quality control checks, and complete traceability of raw materials are critical steps.
Suppliers like Allan Chemical Corporation offer technical-grade and compendial-grade materials with verified purity and impurity limits, along with detailed documentation to meet EU regulatory needs. Partnering with reliable suppliers can simplify the shift from hydroquinone-based products to EU-compliant alternatives, especially when navigating the complexities of alternative brightening agents.

6. Fragrance Allergens and Sensitizers
Fragrance allergens are a unique category of restricted ingredients that require careful management due to their frequent use and potential to cause adverse reactions. Unlike banned substances, these allergens can be included in products, provided they are used within specific limits and clearly labeled. Under Regulation (EC) No 1223/2009, the EU mandates that 26 specific fragrance allergens must be named on product labels if their concentrations exceed defined thresholds. These allergens include commonly recognized substances like limonene, linalool, citronellol, geraniol, eugenol, coumarin, cinnamal, hydroxycitronellal, benzyl alcohol, and isoeugenol, among others. Interestingly, many of these allergens naturally occur in essential oils and botanical extracts, meaning even products marketed as "natural" may require allergen labeling.
The EU does not enforce universal maximum concentration limits for all fragrance allergens. Instead, the regulations depend on the product type and labeling thresholds. For leave-on products like lotions and perfumes, allergens must be listed if they exceed 0.001% (10 ppm). For rinse-off products, such as shampoos and cleansers, the threshold is higher at 0.01% (100 ppm). Additionally, Annex III of the regulation specifies stricter limits for certain substances. For instance, safrole is restricted to 100 ppm in most finished products, but only 50 ppm in oral care items, and it is entirely prohibited in children’s toothpaste. Similarly, furocoumarins, which can be photo-toxic, are limited to their "normal content" in natural essences and must stay below 1 mg/kg in sun care and bronzing products.
The product’s intended use significantly influences how fragrance allergens are regulated. Rinse-off products like body washes and facial cleansers have higher labeling thresholds compared to leave-on products such as creams and serums, which are subject to stricter limits. Additional restrictions apply to products designed for sensitive areas, such as mucous membranes, damaged skin, or formulations for children. These stringent measures encourage formulators to minimize allergen levels or exclude highly sensitizing ingredients altogether, reflecting the EU’s strong focus on consumer safety.
When any of the 26 recognized allergens exceeds the permissible threshold, it must be explicitly declared on the product’s ingredient list. For example, a citrus-scented body wash might need to list limonene and citral derived from essential oils, while a floral perfume could require linalool, geraniol, and citronellol to be included on the label. Non-compliance, such as failing to declare these allergens, can result in regulatory enforcement actions and the removal of products from the EU market.
To ensure compliance, formulators must carefully measure allergen levels and verify label accuracy. This involves integrating thorough checks into their Product Information Files (PIF) and conducting detailed safety assessments. Suppliers of fragrance ingredients play a critical role by providing detailed specifications and test data that confirm allergen content and impurity levels. For U.S. companies exporting to the EU, collaborating with trusted chemical suppliers can simplify the compliance process. For example, Allan Chemical Corporation offers high-purity aroma chemicals and technical-grade solutions tailored to meet these stringent requirements.
Regulatory and quality assurance teams should also review formulations to ensure compliance with restrictions on highly regulated substances like furocoumarins and safrole. Even trace amounts of these substances must stay within the strict limits outlined by EU regulations, underscoring the importance of rigorous testing and accurate labeling practices.
7. Resorcinol and Hair Dye Intermediates
Resorcinol (CAS No. 108-46-3) plays a key role as an oxidation hair dye intermediate in permanent and semi-permanent hair color formulations. However, its usage comes with strict limitations under Annex III of Regulation (EC) No 1223/2009 due to concerns like skin sensitization, eye irritation, and potential endocrine effects.
When combined with aromatic amines (such as p-phenylenediamine) and an oxidizing agent, resorcinol reacts to create color molecules that penetrate the hair shaft. While this process is effective for hair coloring, it can also interact with skin proteins, which has prompted regulators to impose stringent usage limits. Over the years, the Scientific Committee on Consumer Safety (SCCS) has issued several opinions refining the safe-use levels of resorcinol based on updated toxicological findings. Below, we outline the concentration limits, product restrictions, and labeling requirements associated with resorcinol in hair dye products.
Maximum Concentration Limits
Annex III establishes specific concentration limits for resorcinol in both the unmixed colorant base and the final, ready-to-use product. For the unmixed base, resorcinol levels are capped at 3–4%, while the mixed product applied to hair must not exceed approximately 1–2%. For instance, a base containing 3.5% resorcinol, when mixed 1:1 with a developer, results in a final concentration of about 1.75%. Both stages must comply with these limits to ensure regulatory adherence.
For U.S. manufacturers exporting to the EU, it’s critical to calculate concentrations accurately at every stage of formulation. Even if the finished product appears compliant on paper, overlooking the initial base concentration can lead to violations.
Product Category Restrictions
Resorcinol is approved exclusively for oxidative hair dye products intended for scalp hair. Its use in products like eyebrow or eyelash dyes, as well as leave-on formulations, is either prohibited or restricted to professional applications due to increased irritation risks. To comply, manufacturers must confirm that the product type, application time, and rinse-off requirements align with Annex III guidelines.
Additionally, some Annex III entries specify conditions such as pH ranges or processing environments. For example, formulations may need to maintain a pH between 9 and 11, which is ideal for oxidative color development. These parameters must be documented in the Product Information File (PIF) and verified through pilot batches to ensure that the actual pH and active ingredient levels match theoretical calculations.
Mandatory Labeling Requirements
Hair dye products containing resorcinol must include prominent warning labels. Statements like "Contains resorcinol" and "Hair colorants can cause severe allergic reactions" must be displayed clearly and in the local language. Additional warnings, such as age restrictions and patch test instructions, are also required under Annex III.
Labeling compliance is non-negotiable. Failure to include the correct warnings can result in enforcement actions, product recalls, or removal from the EU market. U.S. companies exporting to Europe should carefully review the exact language required by Annex III and ensure translations are accurate. Collaborating with regulatory consultants familiar with EU cosmetic laws can help avoid costly errors and delays.
Purity and Impurity Thresholds
Resorcinol must meet stringent purity standards, with toxic impurities like heavy metals and residual solvents kept at minimal levels (measured in parts per million). Using high-quality, pharmacopeial-grade materials with Certificates of Analysis (CoAs) ensures compliance. Partnering with reputable suppliers, such as Allan Chemical Corporation, can simplify sourcing and documentation.
To maintain compliance, quality assurance teams should integrate purity checks into their routine batch release processes. This involves reviewing CoAs for each batch of resorcinol, verifying that impurity levels meet internal specifications, and recording these checks in the PIF. Analytical testing of both pilot and production batches further ensures that active ingredient levels and impurity profiles align with formulation requirements.

8. Nanomaterials with Updated Restrictions
Nanomaterials bring unique challenges due to their small size – particles under 100 nanometers can behave differently compared to their bulk counterparts. Regulation (EC) No 1223/2009 categorizes nanomaterials separately, requiring specific safety assessments, notifications, and labeling. The March 14, 2024 amendment introduced major updates, adding several nano-forms to the banned substances list in Annex II and restricting hydroxyapatite (nano) in Annex III. These changes reflect growing concerns over the accumulation of insoluble nanomaterials in tissues and potential inhalation risks.
The 2024 update specifically targets nanomaterials, banning several precious metal nano-forms across all cosmetic products. Prohibited materials now include colloidal silver (nano), colloidal gold (nano), copper (nano), colloidal copper (nano), gold (nano), platinum (nano), and related complexes. These materials, once favored in high-end formulations for anti-aging and brightening, were flagged for risks such as systemic exposure, bioaccumulation, and even potential DNA damage. Additionally, styrene/acrylates copolymer (nano) and sodium styrene/acrylates copolymer (nano) have been added to Annex II, halting their use in film-forming or texture-enhancing applications.
For U.S. manufacturers exporting to the EU, these bans demand immediate action. Any formulation containing nano gold, silver, copper, or platinum must be reformulated to comply with the new rules. Unlike some regulations, there are no exceptions based on concentration or product type for these banned materials. This shift signals stricter oversight on product composition, labeling, and purity standards.
Product Category Restrictions
Although most newly banned nanomaterials face outright prohibition, hydroxyapatite (nano) is now limited to specific oral care uses. Under the 2024 amendment, it is only allowed in toothpaste and mouthwash, with its use strictly prohibited in other cosmetics like skincare, hair care, and makeup products.
The restrictions also address inhalation risks. Hydroxyapatite (nano) cannot be used in products that might expose the lungs to respirable particles. This means aerosol sprays, pump sprays, loose powders, or other formats capable of producing airborne particles are not permitted. For example, traditional toothpaste tubes or liquid mouthwash bottles meet the requirements, but pressurized sprays or powdered sachets do not. These distinctions must be documented in the Product Information File (PIF) to ensure compliance.
Maximum Concentration Limits
The amendment also sets precise concentration limits for hydroxyapatite (nano) based on product type. For toothpaste, the limit is 10%, while mouthwash formulations are capped at 0.465%. These thresholds apply to the final product ready for consumer use, not the raw materials or intermediate formulations.
For example, a mouthwash containing 0.5% hydroxyapatite (nano) would exceed the allowable limit and be non-compliant. All contributions must be carefully calculated, verified through analytical testing, and documented in the PIF. U.S. companies exporting to the EU must adhere strictly to these limits to avoid enforcement actions, recalls, or product withdrawals.
Mandatory Labeling Requirements
Nanomaterials in cosmetics must be clearly identified on the product’s ingredient list by adding "(nano)" immediately after the INCI name. For instance, hydroxyapatite (nano) must appear as "Hydroxyapatite (nano)" on the label. Similarly, titanium dioxide in nano form should be listed as "Titanium Dioxide (nano)."
This labeling rule applies to all nanomaterials, regardless of their function – whether as colorants, UV filters, preservatives, or other ingredients. It ensures EU consumers can easily identify nanomaterials and make informed choices. U.S. manufacturers must update their product packaging and artwork to include this designation, ensuring consistency across regulatory, formulation, and packaging teams.
Purity and Impurity Thresholds
While the Annex II and III entries focus on the nanomaterial itself, products must also meet impurity and contaminant standards. Heavy metals like lead (<10 mg/kg), arsenic (<2 mg/kg), and cadmium (<5 mg/kg) must be minimized as much as possible.
For nanomaterials, controlling impurities is especially critical. Their high surface area can increase the bioavailability of trace metals or residual catalysts, making even small amounts more toxic than in bulk materials. To manage these risks, formulators should source nano-ingredients with detailed specifications and Certificates of Analysis (CoAs) that outline heavy metal content, residual monomers, and impurity profiles.
For example, quality assurance measures should include regular purity checks during batch production, with results recorded in the PIF. Beyond heavy metals, safety assessors expect detailed data on nano-ingredients, including particle size, shape, surface area, and coating details. Solubility and behavior in relevant media – such as saliva for oral care products – are also critical to understanding exposure risks. This information must be summarized in the Cosmetic Product Safety Report (CPSR). If safety concerns arise, the European Commission can seek advice from the Scientific Committee on Consumer Safety (SCCS).
9. UV Filters Under Stricter Conditions
The European Union (EU) continues to tighten its regulations on UV filters, maintaining its commitment to consumer safety. Sunscreens, classified as cosmetics under Regulation (EC) No 1223/2009, must adhere to strict guidelines. Only UV filters listed in Annex VI, with their approved maximum concentrations and designated product types, are permitted in cosmetics sold within the EU.
Over time, the EU has introduced stricter measures, driven by ongoing safety evaluations conducted by the Scientific Committee on Consumer Safety (SCCS). These reviews assess factors such as systemic absorption, endocrine disruption, phototoxicity, and risks to sensitive populations. As new findings emerge, the European Commission updates Annex VI. These updates often lower maximum concentration limits, restrict certain filters to specific product categories, or prohibit their use in formulations with potential inhalation risks. For product developers, these changes emphasize the need to incorporate safety considerations early in the formulation process.
Maximum Concentration Limits
Annex VI specifies the maximum concentration limits for approved UV filters, expressed as a percentage by weight (% w/w). Recent SCCS evaluations have led to reduced limits for filters like octocrylene, avobenzone (butyl methoxydibenzoylmethane), and homosalate. These changes require brands to reformulate previously compliant products to meet updated standards.
Take homosalate as an example. SCCS has recommended limiting its concentration and restricting its use to face-only products due to systemic exposure concerns. Similarly, benzophenone-3 (oxybenzone) now has stricter limits for general body products compared to facial applications, with additional precautions for children’s products.
For formulators, these concentration limits shape every aspect of sunscreen development. Achieving high SPF and UVA protection often requires combining multiple filters, ensuring each stays within its Annex VI limit. When a filter’s limit is reduced, existing products must be reformulated, often involving substitutions or adjustments. These changes must be backed by thorough analytical testing and documented in the Product Information File (PIF) to ensure compliance.
Product Category Restrictions
Beyond concentration limits, the type of product also determines how UV filters can be used. Annex VI often specifies which filters are approved for certain product categories, such as face creams, body lotions, or sunscreens. It also distinguishes between rinse-off and leave-on applications, with different limits or outright bans, particularly for products that pose inhalation risks. For instance, a filter might be allowed at a higher concentration in a leave-on sunscreen but face stricter limits in a daily face cream. Aerosol or spray formulations often face additional restrictions due to the potential for generating inhalable droplets.
These restrictions are based on SCCS exposure assessments, which consider factors like the skin area covered, frequency of use, and potential for systemic absorption or inhalation. Stricter limits are often applied to products with higher exposure risks, such as full-body sunscreens or those intended for children. Formulators must carefully define the intended use of their products and ensure that each UV filter complies with its Annex VI requirements before finalizing formulations.
Mandatory Labeling Requirements
Under EU Cosmetic Regulation 1223/2009, products containing UV filters must meet specific labeling requirements. These include the responsible person’s name and address, nominal content, ingredient list (using INCI names), batch number, durability or period-after-opening (PAO) symbol, and any necessary warnings. Sunscreens must also display their SPF value, UVA protection (indicated with a "UVA" symbol in a circle), and clear usage instructions, such as "Apply generously before sun exposure and reapply frequently."
If Annex VI assigns specific warnings or conditions to a UV filter, these must appear on the product label in the local language of each EU Member State where the product is sold. Companies exporting to the EU must adapt their labels to meet these requirements.
Purity and Impurity Thresholds
UV filters must also meet strict impurity limits as outlined by EU guidelines, such as keeping lead levels below 10 mg/kg. Manufacturers must ensure compliance by monitoring impurity profiles and, if needed, implementing purification steps or switching suppliers. Regular testing is essential to maintain acceptable impurity levels.
Staying informed about SCCS opinions and updates to Commission Omnibus Regulations is crucial for compliance. Filters like homosalate, octocrylene, benzophenone-3, and avobenzone are frequently reviewed, and their limits may change. Early awareness of proposed amendments allows manufacturers to adjust formulations proactively, reducing potential disruptions, especially for high-demand sun care products.

10. Heavy Metals and Technical Impurities
Under the EU Cosmetic Regulation 1223/2009, heavy metals like lead, arsenic, cadmium, mercury, and nickel are strictly prohibited as deliberate cosmetic ingredients. Only unavoidable trace amounts from raw materials, production processes, or packaging are allowed. These traces must be minimized as much as possible through stringent manufacturing standards and raw material controls. While some restricted ingredients may be allowed in controlled concentrations, heavy metals are always treated as unintended impurities.
The EU does not enforce a universal limit for heavy metals across all cosmetic categories. Instead, manufacturers rely on guidance values and national regulations to ensure safety and compliance. Technical impurities – such as heavy metal residues in pigments or contaminants like 1,4-dioxane – are managed through concentration limits outlined in Annex III and other relevant standards. Before releasing products to market, the responsible party must confirm that these requirements are met.
Maximum Concentration Limits
Even though heavy metals are not intentionally added, manufacturers must carefully monitor and control trace impurities. Industry practices typically set the following thresholds for finished cosmetics:
- Lead (Pb): below 10 mg/kg
- Arsenic (As): below 2 mg/kg
- Cadmium (Cd): below 5 mg/kg
- 1,4-Dioxane: below 30 mg/kg
These limits serve as practical benchmarks. Manufacturers should follow the ALARA principle (As Low As Reasonably Achievable): if impurity levels are well below these values, maintain or enhance controls; if levels approach these benchmarks, investigate and take corrective action immediately.
Nickel requires extra attention due to its link to allergic contact dermatitis. The EU Nickel Directive limits nickel release to 0.5 µg/cm² per week for items like tools and accessories. This has influenced how formulators address nickel contamination, especially for products with prolonged skin contact or those used near pierced areas.
Product Category Considerations
Although EU regulations do not specify different heavy metal limits for various product types, practical adjustments are made based on exposure risks. Leave-on products, such as lotions, lipsticks, foundations, and eye makeup, demand stricter impurity controls compared to rinse-off products like shampoos or shower gels. This is because leave-on products remain on the skin longer, increasing potential absorption. Color cosmetics, which often use mineral pigments, may naturally have higher heavy metal backgrounds, requiring more rigorous supplier qualifications and frequent testing. Special care is also needed for lip products and items for children, as ingestion risks and sensitivity are greater.
Purity and Impurity Thresholds
Effective impurity control starts with detailed raw material specifications. Manufacturers should set strict limits for heavy metals in key ingredients like pigments, clays, talc, micas, and plant extracts, sourcing materials from suppliers who provide thorough analytical data. Using pharmaceutical- or cosmetic-grade materials that meet established standards (e.g., ACS, USP, NF, FCC) is critical for ensuring safety and compliance.
Suppliers are expected to provide comprehensive documentation, including Certificates of Analysis (CoA) and Safety Data Sheets (SDS), detailing ingredient purity. For U.S. brands aiming to enter the EU market, collaborating with specialty chemical providers can simplify compliance efforts.
Good manufacturing practices (GMP) and regular equipment maintenance are also essential to prevent contamination during production. For example, avoiding corroding steel equipment or contaminated grinding media can help minimize metal residues. Periodic testing of finished products using validated methods like ICP-MS or ICP-OES ensures impurity levels remain within acceptable limits, allowing manufacturers to identify and address trends before they escalate into compliance issues.
If a metal compound is intentionally added, such as a colorant listed in Annex IV, it must follow all relevant EU conditions, including concentration and purity requirements. These ingredients should also be labeled using their International Nomenclature of Cosmetic Ingredients (INCI) name. Compliance with Annexes IV–VI for colorants, UV filters, and preservatives is typically verified through supplier documentation and the CosIng database maintained by the European Commission.
Manufacturers must maintain detailed records of all compliance activities – such as CoAs, analytical reports, supplier declarations, and risk assessments – in the Product Information File (PIF). These records should be retained for at least three years and made accessible for regulatory inspections.
| Aspect | Regulatory Point | Implication |
|---|---|---|
| Heavy metals as ingredients | Not allowed as intentional cosmetic ingredients under EU 1223/2009; only unavoidable traces allowed | Avoid intentional addition of metal salts; treat metals strictly as impurities |
| Example impurity limits | Lead (Pb) <10 mg/kg, Arsenic (As) <2 mg/kg, Cadmium (Cd) <5 mg/kg, 1,4-Dioxane <30 mg/kg | Use these thresholds as internal safety targets during assessments |
| Purity requirements for additives | Must meet purity criteria in Annexes IV–VI, verified via CosIng database | Source from suppliers who can demonstrate compliance with EU purity standards |
| Labeling of trace metals | Safe, unintended impurities do not need to be listed on the ingredient label | Focus on strict impurity controls and thorough documentation rather than labeling requirements |
Recent trends show manufacturers increasingly testing for a wider range of impurities at sub-ppm levels to enhance safety assessments and address public health concerns. Many EU brands exporting to North America and Asia now design impurity specifications to meet or exceed the strictest global standards, simplifying compliance across multiple markets.

Conclusion
Complying with EU Cosmetic Regulation 1223/2009 is a non-negotiable requirement for selling cosmetic products in the EU and EEA markets. Products that fail to meet these standards cannot legally be sold, no matter where they are manufactured. For U.S. and other international brands, understanding and adhering to the regulation’s rules – especially the lists of prohibited and restricted ingredients – is critical for gaining and maintaining access to one of the most tightly regulated cosmetic markets in the world.
The regulation’s primary focus is protecting human health, with Annex II and Annex III outlining banned and restricted ingredients. These rules cover a wide range of specifics, including concentration limits, application areas, and impurity thresholds. Additionally, Annexes IV, V, and VI provide positive lists for colorants, preservatives, and UV filters, meaning every ingredient must be verified for compliance before a product is formulated or launched.
EU regulations are not static; they evolve regularly as new scientific findings emerge. Updates to annexes, such as recent changes to nanomaterial restrictions and planned ingredient bans starting in September 2025, highlight the importance of staying informed. Brands must actively monitor these changes and adjust formulations or labeling as necessary. Relying on outdated ingredient lists is not an option – companies need formal systems for regulatory tracking and responsive reformulation to remain compliant.
Non-compliance carries serious risks, including product recalls, legal issues, and damage to consumer trust. For international brands, failing to meet EU standards can also strain relationships with distributors and retailers, who expect full compliance. To navigate these challenges, businesses must establish strong internal compliance processes and work with reliable suppliers. This includes verifying that all ingredients meet the requirements of Annex II and Annex III, ensuring colorants, preservatives, and UV filters are on the approved lists, and confirming that impurities stay within allowable limits. Every product must include a complete Product Information File (PIF) with a safety assessment by a qualified professional. Additionally, change control procedures should be in place to address any updates to ingredient specifications or regulatory statuses.
Ingredient quality and thorough documentation are key to meeting EU standards, especially when dealing with substances subject to strict impurity and concentration limits.

By treating EU compliance as a global benchmark, brands can elevate their overall safety standards and simplify entry into other markets that follow similar regulatory frameworks. For U.S. companies planning to expand into the EU, the first step is conducting a gap analysis of current formulas to identify banned or restricted ingredients. They should appoint an EU-based Responsible Person, ensure each product has a compliant PIF and safety assessment, and confirm ingredient statuses through CosIng, the European Commission’s Cosmetic Ingredient Database. Upgrading supply chains to work with regulation-savvy suppliers is also crucial for maintaining compliance and avoiding unnecessary reformulation costs.
Staying informed about regulatory changes is equally important. Brands should regularly check the Official Journal of the EU for annex updates and use CosIng to verify ingredient statuses before launching new products or making formulation changes. Establishing a regulatory tracking system or working with specialized consultants can help translate these updates into actionable steps, reducing the risk of non-compliance. Prioritizing safer alternatives to CMR substances, nanomaterials, and other high-risk ingredients can also minimize the likelihood of future disruptions.
