Are There Limits on Ingredients for Cosmetics in China?

Yes, China maintains one of the most comprehensive and strictly enforced ingredient control systems in the global cosmetics industry. For foreign brands entering the Chinese market, understanding these ingredient limits is not optional — it is the single most common cause of NMPA filing rejection. This article provides a detailed breakdown of China’s ingredient regulatory framework, the prohibited and restricted substances lists, maximum concentration limits, and practical strategies for ensuring your formulations comply.

The Regulatory Foundation: Three Key Documents

China’s ingredient control system rests on three regulatory documents that every cosmetics formulator must understand before submitting a product for NMPA filing or registration.

Inventory of Existing Cosmetic Ingredients in China (IECIC)

The IECIC is the master list of ingredients that have been determined to be safe for use in cosmetics sold in China. Any ingredient not on this list is considered “new” and requires additional safety assessment and registration before it can be used. The IECIC is updated periodically — the most recent version (2021) contains over 8,700 ingredients. Key points:

• Ingredients must exactly match the INCI names listed in the IECIC — even minor spelling or formatting differences can trigger a rejection
• Some ingredients on the IECIC have usage restrictions (maximum concentration, product category limitations) noted in the inventory
• If your formulation contains an ingredient not on the IECIC, you must either reformulate or submit a new ingredient safety dossier — a process that can take 6–12 months

Safety and Technical Standards for Cosmetics (STSC)

The STSC (originally the Hygienic Standard for Cosmetics, updated and renamed in 2015 with further amendments) is the technical backbone of China’s cosmetics regulation. It contains three critical lists:

• Part 1: List of Prohibited Substances (1,293 substances)
• Part 2: List of Restricted Substances (47 substances with specific concentration and usage limits)
• Part 3: List of Allowed Preservatives, UV Filters, and Colorants (with permitted concentrations for each)

The STSC is closely aligned with the EU Cosmetics Regulation but contains approximately 50 additional prohibited substances not found on the EU list, making it one of the most restrictive cosmetics ingredient standards globally.

Cosmetics Efficacy Claim Management Measures

While not directly an ingredient restriction document, the 2022 efficacy claim regulations indirectly impact ingredient choices. Products making specific efficacy claims (moisturizing, anti-wrinkle, firming, oil control, etc.) must submit supporting evidence, and the ingredients responsible for the claimed efficacy must be clearly identified in the submission. This means your ingredient selection must be backed by verifiable data — you cannot simply claim efficacy for ingredients that lack published evidence.

Prohibited Substances: The Absolute Ban List

China prohibits 1,293 substances from use in cosmetics — a list that exceeds the EU’s prohibition list. Understanding which substances are banned is critical for any brand reformulating for the Chinese market.

Categories of Prohibited Substances

The prohibited substances fall into several broad categories:

China-Specific Prohibitions

Several substances prohibited in China are still permitted in other major markets. Notable examples include:

• Benzophenone-3 (Oxybenzone) — Permitted in the EU and US at up to 6%, but restricted to 2% in China for rinse-off products and not permitted in leave-on products
• Methylisothiazolinone (MIT) — Permitted in the EU for rinse-off products at 0.0015% but only as a preservative, with tight restrictions on leave-on cosmetics in China
• Homosalate — Permitted as a sunscreen in the US and EU but restricted in China for certain product categories
• Resorcinol — Permitted in the EU in hair products at up to 1.25% but subject to additional restrictions in Chinese regulations

Restricted Substances: Concentration and Usage Limits

China’s restricted substances list contains 47 entries, each with specific limits on maximum concentration in the finished product and allowed product categories. These limits often differ from those in other jurisdictions.

Preservative Limits

China allows 51 preservative substances, each with specific concentration caps. Important differences from other markets include:

• Phenoxyethanol: Maximum 1.0% in China (versus 1.0% EU — same limit, but additional purity specifications apply)
• Parabens: Approved parabens in China have the same limits as the EU, but the use of propylparaben and butylparaben in leave-on products for children under three years old is prohibited
• Benzyl alcohol: Maximum 1.0% (China) versus 1.0% (EU) — but the acceptable daily exposure limits in China are more strictly monitored
• Salicylic acid: Maximum 0.5% for leave-on products, 3.0% for rinse-off products, and explicitly prohibited in products for children under three years old

UV Filter Limits

Sunscreen active ingredients are among the most tightly regulated substances in China. The STSC currently lists 27 approved UV filters with specific concentration limits:

• Zinc oxide: Maximum 25% (as a physical sunscreen agent)
• Titanium dioxide: Maximum 25%
• Butyl methoxydibenzoylmethane (Avobenzone): Maximum 5%
• Octocrylene: Maximum 10% (note: this is being actively reviewed by the EU for safety concerns, and China may follow)
• Ethylhexyl methoxycinnamate (Octinoxate): Maximum 10%

Any product making SPF or UV protection claims must contain only these approved UV filters within their permitted concentration ranges. Using a UV filter not on the approved list, even if it is permitted in your home market, will result in automatic rejection of your NMPA filing.

Colorant Limits

China’s list of permitted colorants follows the EU framework with some additions. Each colorant is specified by Color Index (CI) number and may have additional restrictions:

• Certain CI numbers permitted in the EU are not on China’s list
• Lake and salt forms are considered separately — a colorant approved in its free-acid form may not be approved as a lake
• Cosmetic products containing non-permitted colorants are classified as adulterated and subject to recall and fines

Fragrance Ingredient Restrictions

Fragrance ingredients face particular scrutiny in China. Unlike in most other major markets where fragrance formulas can be partially withheld as trade secrets, China requires full disclosure of all fragrance components in the formulation submission. Furthermore, 26 fragrance allergens must be declared on the product label when present above specified thresholds (0.01% for leave-on products, 0.001% for rinse-off products).

Many global fragrance houses now offer “China-compliant” versions of their popular formulations. If your brand uses proprietary fragrance blends, ask your fragrance supplier for their China-compliant alternative before initiating the NMPA filing process.

How Ingredient Limitations Affect Global Brands

The practical implication of China’s ingredient controls is that foreign brands often need to reformulate products for the Chinese market. This is common and expected — few global brands maintain identical formulations across all markets. The key considerations are:

Reformulation Strategies

• Category A: Identical formulation works — Simple formulations with basic ingredients (glycerin, water, common emollients, standard preservatives) often pass without changes
• Category B: Minor adjustments needed — Products containing common restricted ingredients (salicylic acid, certain parabens, specific fragrances) may need concentration adjustments or alternative preservatives
• Category C: Significant reformulation required — Products with novel ingredients, unique preservative systems, non-standard UV filters, or proprietary fragrance blends typically need full reformulation

Verifying Ingredient Compliance

How do you check whether your ingredients comply before submitting an NMPA filing? Several resources are available:

• NMPA online database: The NMPA maintains a searchable online database of approved ingredients that can be queried for IECIC status and restrictions
• Third-party regulatory databases: Services such as Cosmetic Observatory, SGS, and Bureau Veritas offer China-specific ingredient compliance checks
• Regulatory consultants: Specialized China cosmetics regulatory consultants can provide formulation review and compliance opinions
• Agent pre-review: Your NMPA filing agent should conduct a full formulation review before submission

Investing in ingredient compliance checking before filing is far more efficient than fixing a rejected submission. A typical formulation review costs a few hundred dollars and identifies issues in 1–2 days — compared to weeks or months lost in a rejection cycle.

Recent Regulatory Trends

China’s ingredient regulatory environment is not static. Key trends to watch include:

• Harmonization with international standards: The 2021 regulations moved China closer to the EU framework, and this convergence is expected to continue
• Increased scrutiny of nano-materials: Nanomaterials in cosmetics face additional safety assessment requirements, with a separate inventory under development
• New ingredient registration simplification: The NMPA has indicated it will streamline the registration process for genuinely new to China that have established safety records in other major markets
• Post-market surveillance strengthening: Ingredient compliance is now monitored throughout the product lifecycle, not just at the filing stage — meaning reformulations after filing must maintain regulatory compliance

Staying current with these trends requires ongoing attention to NMPA announcements. Many foreign brands subscribe to regulatory update services or work with consultants who monitor regulatory changes on their behalf.

Understanding China’s ingredient limits is the single most important technical step in preparing for NMPA filing. With careful pre-submission ingredient screening and the right reformulation strategy, foreign brands can successfully bring compliant products to the world’s most dynamic beauty market.
