Introduction

This standard test substance is banned substances of "Hygienic Standard for Cosmetics" shall consist of not as a cosmetic raw material, component Tim Added to cosmetics. If technically unavoidable banned substances as impurities into cosmetics, the finished cosmetic products shall comply with the "cosmetic Wei Health standard "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 Determination of hexachlorophene High Performance Liquid Chromatography
