Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard is under the jurisdiction of the National Spice and Fragrance Cosmetics Standardization Technical Committee (SAC/TC257). This standard was drafted. Hebei Food Inspection Institute (National Fruit and Agricultural Processing Products Quality Supervision and Inspection Center), Suzhou Genealogy Testing Technology Co., Ltd., Hebei Entry-Exit Inspection and Quarantine Bureau, Hebei Medical University. The main drafters of this standard. Fan Sufang, Li Qiang, Zhang Yan, Ma Junmei, Yu Hao, Ai Lianfeng, Lu Pin, Ma Chunling, Wen Di, Ye Zhuhong, Dai Dan, 翟 Hong stability.

Introduction

The tested substances in this standard are metobase, saponin, aconitine, colchicine, atropine, and strychnine. Prohibited substances specified in the Code of Practice (2015 Edition). A banned substance is a substance that cannot be added to a cosmetic as a raw material for cosmetic production. Cosmetics Safety Technical Specifications (2015 edition) stipulates. If it is technically impossible to avoid the banned substances as impurities into the cosmetics, a safety risk assessment should be carried out to ensure Under normal, reasonable and foreseeable conditions of use, no harm may be caused to human health. At present, China has not specified the limit value of these substances. The formulation of this standard only provides testing methods for the determination of these substances in cosmetics. Determination of 10 alkaloids in cosmetics Liquid chromatography tandem mass spectrometry

1 Scope

This standard specifies the cosmetics of the Middle East, such as saponin, alkaloid, aconitine, hypaconitine, aconitine, colchicine, atropine, and Determination of the content of Ning, camptothecin and pilocarpine by liquid chromatography-tandem mass spectrometry (LC-MS/MS) Rate and precision, tolerance is poor. This standard applies to cream emulsion, water-based cosmetics, Middle East, alkaloids, aconitine, aconitine, aconitine, colchicum Determination of alkali, atropine, strychnine, camptothecin, pilocarpine content. The detection limit of this standard method is. atropine is 5μg/kg, hypoaconitine and neoaconitine are 7.5μg/kg, scopolamine, saponin, Aconitine, colchicine, strychnine, camptothecin, pilocarpine is 12.5μg/kg; the limit of quantification of this standard method. atropine is 12.5μg/kg, Secondary aconitine and aconitine were 25μg/kg, scopolamine, saponin, aconitine, colchicine, strychnine, camptothecin, pilocarpine 50 μg/kg.
