高效液相色谱法测定化妆品中10种限用物质
Determination of 10 Kinds of Restricted Substances in Cosmetics by High Performance Liquid Chromatography with Photodiode Array Detector
摘要
Abstract
A high performance liquid chromatography (HPLC) coupled with photodiode array detector (PDAD) method was developed for the determination of content of hydroquinone, phenol, salicylic acid, 2-phenoxyethanol, methyl 4-hydroxybenzoate, ethyl 4-hydroxybenzoate, propyl 4-hydroxybenzoate, butyl 4-hydroxybenzoate, dichlorophcn and triclosan in cosmetics sample. The restricted substances were extracted with acetonitrile in sonic bathing for 10 min. The chromatographic separation was completed with a column of Lichrosorp RP-18 (250 mm ×4. 6 mm, 5 μm) using methanol acetonitrile - ammonium acetate ( pH 4. 0) as mobile phase. The quantification was earriod out by the external standard method. The calibration curves of 10 restricted substances were linear in the range of 0. 01 -0. 1 g/L. The recoveries at three spiked levels of 50, 100, 200 mg/kg ranged from 80% to 113%. The relative standard deviations(RSD, n =7) ranged from 2. 2% to 10. 0% and the quantitation limits were in the range of 10 - 50 mg/kg. The method was rapid, easy, accurate and sensitive, and could meet the detection requirements for domestic and foreign limited substances in cosmetics.关键词
