A Simple Quantitative Determination of Ethanol in Drugs by Gas Chromatography using the Headspace Analytical Technique. III. Toiletries

Abstract

A simple quantitative determination of ethanol content in 57 toiletries was attempted using gas chromatography in combination with head-space technique. The apparatus used was a gas chromatography equipped with hydrogen flame ionization detector (FID), and the column packing was PEG 20M/Chamelite CS. Samples used were eau de cologne, hair tonics, hair liquids, aftershave lotions, Iotions for women, milk lotions, and dentifrices. When propanol was used as an internal standard, ethanol content in both liquified and solidified samples was also capable of being calculated by the same equation. Results obtained by the head-space technique were close to the values determined by the use of a distillate in the dichromate oxidation method.
