Summary

On July 8, 2022, China National Institutes for Food and Drug Control (NIFDC) launched public consultation on one draft testing methods for eight hair perming agents. Cosmetic stakeholders can send suggestions to hzpbwh@nifdc.org.cn before July 31, 2022.

This method introduces the determination of eight hair perming agents in cosmetics by HPLC, including Thioglycollic Acid. It is developed to replace the method specified in STSC 2015 for the determination of Thioglycollic Acid. Compared to its predecessor, the new method is further optimized to deal with samples with different properties, and is applicable to six more Thioglycollic Acid Esters, covering those newly appear in cosmetics registration and notification, as well as those listed in Inventory of Existing Cosmetic Ingredients in China (IECIC) and EU Cosmetics Regulation.
