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. Currently we have not yet provided these substances limited value, the present standards, the determination of these substances in cosmetics only provide detection methods. Cosmetics banned substances glycol monomethyl ether, Glycol ether and diethylene glycol ether Gas chromatography

1 Scope
