• TITLE: Determination of Compositions in Cosmetics by Multiple-Instrument

  AUTHORS: Changming Zhang, Shaoqing Guo, Changgen Huang

  KEYWORDS: Cosmetic; Analysis, Multi-Instruments, HPLC, FTIR

  JOURNAL NAME: American Journal of Analytical Chemistry, Vol.2 No.8, December 7, 2011

  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.
