China's National Medical Products Administration (NMPA) governs cosmetic ingredients through a stringent regulatory framework, primarily centered on the Cosmetic Supervision and Administration Regulation (CSAR) and its implementing rules. Compliance for any ingredient hinges on its status as either an 'existing' or 'new' cosmetic ingredient, alongside comprehensive safety assessment requirements.
The CSAR Framework and Ingredient Classification
The CSAR, effective January 1, 2021, fundamentally reshaped China's cosmetic regulatory landscape. A core tenet is the classification of ingredients into two categories: existing and new. Existing ingredients are those listed in the Inventory of Existing Cosmetic Ingredients in China (IECIC), while any ingredient not on this list is considered a New Cosmetic Ingredient (NCI) and requires specific pre-market approval or notification.
- **Existing Cosmetic Ingredients (IECIC):** Ingredients listed on the IECIC are generally permitted for use, provided they adhere to any specified restrictions or conditions. However, even existing ingredients require a safety assessment report for their intended use in a cosmetic product.
- **New Cosmetic Ingredients (NCI):** Ingredients not found on the IECIC must undergo a rigorous NCI registration (for high-risk ingredients) or notification (for general ingredients) process with the NMPA, supported by extensive safety data.
Safety Assessment and Restricted Substances
Under CSAR, all cosmetic ingredients, whether existing or new, must be supported by a comprehensive safety assessment report. This report evaluates the ingredient's safety profile based on its intended use, concentration, and exposure. The NMPA also maintains lists of prohibited and restricted substances, similar to positive and negative lists found in other jurisdictions.
- **Prohibited Substances:** These ingredients are entirely forbidden for use in cosmetic products within China.
- **Restricted Substances:** These ingredients may be used only under specific conditions, which can include maximum concentration limits, purity requirements, or restrictions on product type (e.g., rinse-off vs. leave-on) or target consumer age.
- **Positive Lists:** Certain categories, such as preservatives, colorants, UV filters, and hair dyes, are regulated via positive lists. Ingredients in these categories must be explicitly listed by the NMPA and adhere to their specified conditions of use.
For R&D and regulatory teams, verifying the current status and specific conditions of use for any ingredient intended for the Chinese market is critical. The applicable limits and requirements are determined by the ingredient's classification (existing or new), its intended function, the product category, and the specific concentration of use.
