Official Notice

NMPA Announcement on Matters Related to the Management of the Inventory of Existing Cosmetic Ingredients in China (2025 No. 61)

According to the Cosmetics Supervision and Administration Regulations (CSAR), cosmetic new ingredients that have been registered or filed and have completed a 3-year safety monitoring period without any safety issues are included in the IECIC. To facilitate the management of existing cosmetic ingredients, the NMPA divides the IECIC into List I and List II.

• Partial modifications and improvements were made to the IECIC published by the NMPA in 2021, managed as IECIC I.
• Cosmetic new ingredients that have completed the safety monitoring period are included in IECIC II.

IECIC II: N-Acetylneuraminic Acid and β-Alanyl Hydroxyprolyl Diaminobutyric Acid Benzylamide have completed the 3-year safety monitoring period and, upon evaluation, the NMPA has included these two ingredients in IECIC II.

IECIC I:

• The item "Maximum Historical Usage Level" is no longer retained.
• The Chinese or INCI/English names of ingredients with serial numbers 01371, 01372, etc., have been standardized. For example, the Chinese name for "滨海剌芹（ERYNGIUM MARITIMUM）提取物" was corrected to "滨海刺芹（ERYNGIUM MARITIMUM）提取物," and "LOPHATHERUM GRACILE LEAF POWER" was corrected to "LOPHATHERUM GRACILE LEAF POWDER."

For example, for Guar Gum (CYAMOPSIS TETRAGONOLOBA), the remark "includes Galactomannan (D-GALACTO-D-MANNAN/GALACTOMANNAN)" was added.
