New Ingredients, New Rules: NMPA Registration, Filing & Post‑Market Monitoring Updates

2026 marks a pivotal shift in China’s cosmetic new ingredient (NCI) regulation. Under CSAR, NCIs follow risk-tiered management, only five high-risk categories (preservation, UV filter, colourant, hair dye, whitening) require registration; all others are filed. On 15 July, NMPA Announcement No. 59 and the NIFDC Technical Guidelines for NCI Registration and Filing Dossiers took effect, replacing the 2021 rules: the “higher-risk” scope is narrowed from ten to five functions, toxicology is tiered by scenario, alternative non-animal data are accepted, and existing safety/food-use history can be reused.

In parallel, the revised MEE Measures for the Environmental Management Registration of New Chemical Substances (Decree No. 12), aligned with the Ecological Environment Code and effective 15 August, removes the former cosmetic-carve-out: any substance not on IECSC, including a cosmetic new ingredient, may trigger a separate MEE simplified or standard registration by the domestic manufacturer/importer. An NCI cleared by NMPA is therefore not automatically free from MEE control, adding a second compliance track for sponsors.
