GB/T 30930-2014

This standard specifies a high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) method for detecting nine prohibited aromatic amines, including benzidine, in cosmetics. It is applied by regulatory bodies and cosmetic manufacturers in China to screen and quantify these carcinogenic substances in raw materials and finished products, ensuring compliance with national safety regulations. The method is critical for quality control in the cosmetics industry, particularly for products like hair dyes, creams, and lotions that may contain banned dye intermediates.
