Introduction

The standard test substance is banned substances of "Hygienic Standard for Cosmetics" shall consist of not as a cosmetic raw material, component Added to cosmetics. If technically unavoidable banned substances as impurities into cosmetics, the finished cosmetic products should follow the "Cosmetics Health standards "General requirements for cosmetics, that is, under normal and reasonably foreseeable conditions of use, should not cause harm to human health. At present, China has not yet specified the substance of limited value, the present standards, the determination of these substances in cosmetics only provide detection methods. Cosmetics forty-one kinds of glucocorticoids Determination Liquid chromatography/tandem mass spectrometry and thin layer chromatography

1 Scope

This standard specifies the 41 kinds of cosmetics glucocorticoids liquid chromatography/tandem mass spectrometry and thin layer chromatography two kinds of measuring methods. This standard liquid chromatography/tandem mass spectrometry method used in cosmetics glucocorticoid quantitative determination, the detection limit 0.03μg/g, the limit of quantification was 0.1μg/g. The standard method is suitable for cosmetic tlc glucocorticoid qualitative screening. Spotting an amount of 10mg, the detection limit is 50μg/g; when spotting an amount of 20mg, the detection limit of 25μg/g.
