On July 30, 2025, China National Institutes for Food and Drug Control (NIFDC) initiated a public consultation on three draft testing methods for cosmetic products. Comments can be submitted through NIFDC's Cosmetic Standards Formulation and Revision Management System by August 20, 2025.1
The three drafts are intended to supplement and refine the existing testing methods listed in Safety and Technical Standards for Cosmetics (STSC). An overview of each method is provided below.
| No. | Testing Method | Introduction |
| 1 | Determination of Diethylene Glycol in Cosmetics (Draft) | - This method specifies the use of gas chromatography-mass spectrometry to determine the content of diethylene glycol (DEG) in cosmetic products. It is applicable to various product forms, including creams, emulsions, aqueous and oil-based liquids, gels, powders, and wax-based formulations. - Currently, STSC only includes testing requirements for DEG in cosmetic ingredients, with no established method for finished products. |
| 2 | Determination of Dyclonine Hydrochloride and Other 22 Kinds of Components in Cosmetics (Draft) | - This method outlines the technical requirements for the qualitative screening and quantitative determination of 23 ingredients in cosmetics by means of high performance liquid chromatography-tandem mass spectrometry. It is applicable to aqueous liquids, creams, emulsions, gels, oil-based liquids, and powder cosmetics. - Compared with the existing method in STSC, this new method expands the scope of ingredients tested from 7 to 23, and has been optimized to also apply to powder formulations. |
| 3 | Determination of 16α-Hydroxyprednisonlone and Other 128 Kinds of Components in Cosmetics (Draft) | - This method specifies the use of high performance liquid chromatography-mass spectrometry for the qualitative and quantitative determination of 129 ingredients in cosmetics. It covers a variety of formulations, including creams, emulsions, aqueous and oil-based liquids, gels, powders, and wax-based cosmetics. - Built upon the existing standard within STSC, this new method expands the list of detectable ingredients from 63 to 129, and incorporates optimizations to address powder and wax-based product testing. |
