Introduction

The standard test substance is banned substances of "Hygienic Standard for Cosmetics" provisions, 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. China has yet to establish these limit values \u200b\u200bsubstances present standards, the determination of these substances in cosmetics only provide detection methods. Cosmetics chlorpropamide, tolbutamide and carbutamide Determination of three kinds of substances sulfonylurea disabled
