Testing methods for azelaic acid and other cosmetics raw materials in China have been proposed by the National Institutes for Food and Drug Control (NIFDC) on July 12, 2023.
To ensure the highest level of safety and effectiveness for cosmetics, the NIFDC has drafted three experimental methods: “Testing Method for Azelaic Acid and Potassium Azeloyl Diglycinate in Cosmetics” (draft for public consultation), “Photo-Reactive Oxygen Species (ROS) Measurement Test” (draft for public consultation), and “Determination of Selenium Disulphide in Cosmetics” (draft for public consultation). This blog post aims to provide a concise overview of each method and the institute’s call for public feedback.
Testing method for azelaic acid and Potassium Azeloyl Diglycinate in cosmetics
- This method specifies the determination of azelaic acid and potassium azeloyl diglycinate in cosmetics by high performance liquid chromatography.
- This method is applicable to the determination of azelaic acid and Potassium azeloyl diglycinate in creams and lotions, liquids, gels, powders, muds and films.
- The purpose of this method is to strengthen the supervision and management of cosmetics, and further improve the safety of the use of cosmetics.
Photo-reactive oxygen species (ROS) measurement test
- This testing method is designed to predict and evaluate the potential phototoxicity of chemical raw materials for cosmetics.
- This method specifies the basic requirements and methods for the determination of photo-reactive oxygen species (ROS) of chemical raw materials for cosmetics.
- This method is applicable to evaluate the potential phototoxicity of chemical raw materials for cosmetics.
Determination of selenium disulphide in cosmetics
- The purpose of this method is to strengthen the supervision and management of cosmetics, and further improve the safety of the use of cosmetics.
- This method specifies the determination of selenium disulphide in cosmetics by hydride atomic fluorescence photometric method.
- This method is applicable to the determination of selenium disulphide in anti-dandruff shampoo cosmetics containing selenium disulphide.
How to submit feedback
The NIFDC invites individuals and relevant stakeholders to provide their opinions on the three draft testing methods. Feedback should be submitted by August 13, 2023, using the provided “Feedback Form” to the email: hzpbwh@nifdc.org.cn. Participants can contribute to improving cosmetic safety standards and enhancing the effectiveness of these testing methods.
