Abstract:

To establish a liquid-liquid extraction HPLC-MS/MS method for the identification and quantification of acrylamide in three cosmetics matrixes. The cosmetics were dissolved in dichloromethane and the acrylamide was extracted with 0.1% formic acid. The extracted solution was separated on an ACE EXCEL 3 C18-AR (100×4.6 mm, 3 μm) chromatographic column with a mixture of 0.1% formic acid and acetonitrile as mobile phase for isocratic elution and detected with a triple quadrupole mass analyzer using ESI with positive ionization. Ions was monitored in the multiple reaction mode. The acrylamide was identified with relative retention time and ion abundance ratio, and quantified by internal standard method. The established method showed a good linearity in the mass concentration range of 2.5-2 500 μg/L with a LOQ of 0.025 mg/kg for acrylamide in three kinds of cosmetics matrix. The LOD of oil and emulsion matrix were 0.005 mg/kg, and the LOD of cream-like matrix was 0.008 mg/kg. The extraction recovery and precision were 86.9%-113.5% and 0.6%-10.4%, respectively. The established liquid-liquid extraction HPLC-MS/MS method is proved to be accurate and sensitive, and can be applied to determine acrylamide in different cosmetic products.

Key words: liquid-liquid extraction method, HPLC-MS/MS, acrylamide
