On January 22, 2025, China National Institutes for Food and Drug Control (NIFDC) released nine testing methods for public consultation, with feedback accepted until February 21, 2025. One of the methods is the Determination of Total Fluoride in Toothpaste (Draft for Comments).

This method specifies the application of gas chromatography for measuring total fluoride content in toothpaste. The existing standard for fluoride testing in toothpaste, GB/T 8372-2017 Toothpaste, has limitations such as lengthy sample preparation, lack of positive confirmation techniques, and the potential damage caused by derivatization reagents to instruments and materials. The new method optimizes these aspects, addressing the shortcomings of the current standard, and filling the gap in fluoride detection within the Safety and Technical Standards for Cosmetics.
