The wide bore capillary column HP 1701(15 m×0 53 mm i d ×1 0 μm) has been used to analyze benzyl alcohol, methyl p hydroxy benzoate, ethyl p hydroxy benzoate, propyl p hydroxy benzoate, and butyl p hydroxy benzoate in cosmetics. The results showed that these preservatives could be separated with the capillary column completely and their peaks were not interfered with those of other components in cosmetics. The detection limits were 13 ng, 70 ng, 70 ng, 100 ng and 100 ng respectively and the linear range was 50 ng-500 ng.
