Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard proposed by the China Light Industry Federation. This standard by the National Spice cosmetics Standardization Technical Committee (SAC/TC257) centralized. This standard was drafted. China Academy of Inspection and Quarantine, Shanghai Daily Chemical Industry Institute. The main drafters of this standard. Ma Qiang, Li Wentao, Meng Xian double, Bai Hong, Guo Xingzhou, Fu Yan Ling, Xia Fut Fu, Shen Min.

Introduction

The standard test substance of the material is a product of China's "Cosmetic Safety Technical Code" banned substances. Prohibited substances are those that can not be added to cosmetics as a raw material for the production of cosmetics. "Cosmetics Safety Specifications" rules Determine. If technically unavoidable banned substances as impurities into the cosmetics, safety risk assessment should be carried out to ensure that the normal, reasonable and may Under the foreseeable conditions of use, no harm to human health may occur. At present, China has not provided for the limited value of these substances, the development of this standard, only for the detection of these substances in cosmetics to provide testing methods. Determination of topiramate in cosmetics High performance liquid chromatography

1 Scope

This standard specifies the HPLC method for the determination of topiramate A and parmazine O in cosmetics. This standard applies to creams, lipsticks, water agents, loose powder and shampoo Cosmetics in the parmazine A and padimate O Determination. The detection limit and the limit of quantitation of this standard. the detection limit of 2 and 4 mg/kg of marmite ester A and marmite ester is 5 mg/kg.
