Abstract:

A method based on gas chromatography-tandem mass spectrometry (GC-MS/MS) was developed for the analysis of 5 phenolics compounds (phenol, hydroquineone, resorcinol, 4-butylresorciol, phenylethyl resorciol) in cosmetics. The phenolics compounds were extracted from cosmetics by supersonic extraction with 0.03 mol/L potassium dihydrogen phosphate solution, purified by HLB solid phase extraction column, and analyzed via GC-MS/MS after filtration with organic filtration membrane (0.22 μm). Separation was performed on a SH-Rtx-1701MS chromatographic column (30 m×0.25 mm×0.25 μm) by GC-MS/MS with an electrospray ionization (EI) source in the MRM mode. The external standard method was used for quantitative determination. The 5 phenolics compounds can be analyzed within 10 min under the optimum conditions, and it exhibits a good linearity with the standard correlation coefficients (R2) of not less than 0.999 in their respective concentration ranges of 5-200 μg/L. The limited of determination (LODs) are 1.5-3.0 μg/L and the limits of quantitation (LOQs) are 5.0-10.0 μg/L, respectively. The recoveries at three standards are 73.5%-111.8%, and the relative standard deviations (RSDs) are between 1.0% and 11.1% (n=6). The proposed method is accurate, reliable, simple and convenient, and is suitable for determination of phenol whitening active components in cosmetics.

Key words: gas chromatography tandem mass spectrometry (GC-MS/MS), solid phase extractions, cosmetics, phenolic compounds (phenols)
