On July 30, 2025, China's National Institutes for Food and Drug Control (NIFDC) released three draft testing methods, aimed at detecting prohibited ingredients in cosmetics, including substances such as diethylene glycol, dyclonine hydrochloride, and 16α-hydroxyprednisolone. The comment period is open until August 20, 2025, and feedback can be submitted via NIFDC's Cosmetic Standards Formulation and Revision Management System.
Details are as follows:
Testing Method |
Scope |
Determination of Diethylene Glycol in Cosmetics (Draft) |
This method specifies the procedure for determining the content of Diethylene Glycol in cosmetics using gas chromatography-mass spectrometry). It applies to creams and lotions, liquids (water- or oil-based), gels, powders, and wax-based cosmetics. |
Determination of Dyclonine Hydrochloride and other 22 Kinds of Components in Cosmetics (Draft) |
This method specifies the procedures for the qualitative screening and quantitative determination of 23 substances, including Dyclonine Hydrochloride, in cosmetics using high performance liquid chromatography-tandem mass spectrometry. It applies to water-based liquids, creams and lotions, gels, oil-based liquids, and powder cosmetics. |
Determination of 16α-Hydroxyprednisonlone and other 128 kinds of components in cosmetics (Draft) |
This method specifies the procedure for the qualitative and quantitative determination of 129 substances, including 16α-hydroxyprednisolone, in cosmetics using high performance liquid chromatography-mass spectrometry. It applies to creams, lotions, liquids (water- or oil-based), gels, powders, and wax-based cosmetics. |
