Introduction

The standard test substance o-phenylenediamine, m-phenylenediamine is of banned substances, "Hygienic Standard for Cosmetics" provisions shall not be a make-up Product raw materials, component added to cosmetics. If technically unavoidable banned substances as impurities into cosmetics, the cosmetics Finished products should meet the "Hygienic Standard for Cosmetics" General requirements for cosmetics, that is, under normal and reasonably foreseeable conditions of use, people may not Body health hazards. 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 p-phenylenediamine, o-phenylenediamine and m-phenylenediamine Determination
