High performance liquid chroma-tography, HPLC method for determining the content of methanol Imidazole in cosmetics is specified in this standard, which is suitable for water, cream and emulsion cosmetics. The detection limit of the method is 0.33 mg/kg, and the quantification limit is 1.0 mg/kg. The method is separated by methanol extraction of the sample, centrifugal filtrate, reversed phase high performance liquid phase chromatograph, and quantitative analysis by diode array Detector. This standard provides a scientific basis for the detection of methanol Imidazole in cosmetics, which is helpful for product mass control and safety assurance.
