Analysis of Methanol in Ethanol-based Sanitizer

Introduction

A variety of analytical methods have been developed, validated and put in use for analysis of methanol in ethanol-based sanitizers across the world. In Japan, for example, methods using gas chromatography (GC) are standardized by the Japanese Industrial Standards (JIS) K 8101 : 2006, the Japan Alcohol Association Standard JAAS001 : 2012 and the Predetermined Analysis Method of the National Tax Agency Item 11. With a recent surge in demand for ethanol as a sanitizer, test methods standardized by the these agencies can also be applied to the quantitation of methanol in ethanol-based sanitizers. In this article, methanol in ethanol-based liquid and gel sanitizers was analyzed. The concentration of standards was 630 ppm to match the maximum residue level set by the U.S. Food and Drug Administration (FDA). The results obtained in this article were solely based on the comparison between the sample and standard chromatograms.
