Abstract
In this research,an analytical method based on high performance liquid chromatography with a variable wavelength detector( HPLC-VWD) was established for the simultaneous determination of five quaternary ammonium preservatives( cetrimonium bromide,cetalkonium chloride,miristalkonium chloride,lauralkonium chloride and benzethonium chloride) in cosmetics. Preservatives had good lineafity within 10 ~ 200 μg / m L( correlation coefficient,R2 0. 998),limits of detection ranged from 1. 11 to 1. 97 μg / m L,and the average recoveries were obtained in the range of 77. 1 % ~ 110. 2 %. This method is fast,and it has low limit of detection and high recovery.
