Introduction

The tested substances in this document are prohibited raw materials stipulated in my country's "Cosmetics Safety Technical Specifications (2015 Edition)". Prohibited raw materials refer to substances that cannot be used as cosmetic raw materials. The "Cosmetics Safety Technical Specification (2015 Edition)" stipulates that if the technology When banned substances are brought into cosmetics as impurities in the above-mentioned inevitability, the state's limited amount shall comply with its regulations; if the limit is not specified, it shall be carried out. Safety risk assessment ensures that no harm to human health will occur under normal, reasonable and foreseeable use conditions. At present, my country has not stipulated the limit value of these substances. The formulation of this document only provides detection methods for the determination of these substances in cosmetics. Determination of banned substances Bemego and its salts in cosmetics High performance liquid chromatography Warning---Personnel using this document should have practical experience in formal laboratory work. This document does not indicate all possible safety issues question. The user is responsible for taking appropriate safety and health measures and ensuring compliance with the relevant state regulations.
