Abstract
An analysis method based on multi-instruments analysis technique coupled solvent extraction to determine compositions of unknown cosmetic were established. The multi-instruments involve high-performance liquid chromatography (HPLC), X-ray diffraction (XRD) and Fourier transform infrared (FTIR). The cosmetic sample was separated and enriched into 4 fractions by the solvent extraction. The compounds were defined as mercuric ammonium chloride, liquid paraffin, etc.
