,On January 12, 2026, the National Medical Products Administration (NMPA), Announcement No. 1 of 2026 incorporates five test methods into the Cosmetic Safety Technical Specifications (2015 Edition). These methods, drafted and approved by the NMPA Cosmetics Standardisation Technical Committee Director's Meeting, aim to strengthen physicochemical testing standards for cosmetic safety, focusing on the detection of prohibited, restricted, or contaminant raw materials to protect consumer health. Newly added test methods: 1. Test Methods for Six Raw Materials Including Cannabidiol in Cosmetics: Covers prohibited substances such as cannabidiol (CBD); likely uses techniques like HPLC-MS for quantification. 2. Test Methods for Diethylene Glycol in Cosmetics: Targets diethylene glycol as a potential contaminant; analytical method probably involves gas chromatography (GC) or similar. Revised test methods: 1. General Rules for Physicochemical Testing Methods: Updates overarching guidelines for cosmetic analysis, including sample preparation, instrumentation, and validation. 2. Test Methods for 23 Raw Materials Including Procainamide in Cosmetics: Revises detection for substances like procainamide (an antiarrhythmic agent potentially misused); may employ HPLC or spectrometry. 3. Test Methods for 124 Raw Materials Including 6?-Methylhydrocortisone in Cosmetics: Expands on 124 ingredients, exemplified by 6?-methylhydrocortisone (a corticosteroid); focuses on multi-analyte screening via advanced chromatography. Implementation dates: 1. General Rules for Physicochemical Testing Methods: July 1, 2026. 2. The other four methods: January 1, 2027. Early adoption is encouraged for cosmetic registration and filing testing. Pre-implementation testing can use existing methods.
