Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard is proposed by China Light Industry Federation. This standard is under the jurisdiction of the National Standardization Technical Committee on Fragrance & Fragrance Cosmetics (SAC/TC257). This standard was drafted by. Shanghai Quality Supervision, Inspection and Technology Institute (National Cleaning Product Quality Supervision and Inspection Center), Shanghai Daily Use Institute of Chemical Industry. The main drafters of this standard are. Gu Yuxiang, Yan Chenghua, Xiong Wei, Du Gaofei, Shen Min, Zhou Zelin, Zhou Jing, Dai Yanyun, Yu Dan, and Kang Wei.

Introduction

The tested substances in this standard are banned substances stipulated in the “Safety Technical Specifications of Cosmetics” in China. Prohibited substances refer to substances that cannot be added to cosmetics as ingredients for cosmetics production. "Cosmetic Safety Technical Specification" . If it is technically unavoidable that banned substances are brought into cosmetics as an impurity, a safety risk assessment should be conducted to ensure that it is normal, reasonable and acceptable. Under the foreseen conditions of use, no harm to human health may occur. At present, China has not stipulated the limit value of these substances. The formulation of this standard only provides testing methods for measuring these substances in cosmetics. Skin care cosmetics banned substances Determination of Lejuku and Keteite

1 Scope

The current standard stipulates the use of high-performance liquid chromatography and gas chromatography-mass spectrometry methods for the banned substances Lokachi and Ketong in skin care cosmetics. This standard applies to creams, lotions, and water cosmetics in the determination of music killing Ke and Ke Te. The detection limits of this standard for high-performance liquid chromatography for lecicarb and clotris were 7 mg/kg and 16 mg/kg, respectively, and the lower limit of quantitation was 20mg/kg, 50mg/kg; when using solid-phase extraction, the detection limits of Lactazone and Krypton were 3.5mg/kg and 8mg/kg, respectively; Not for 10mg/kg, 25mg/kg. The gas chromatogram-mass spectrometry of this standard has a detection limit of 2 mg/kg for Lactazone and Chlorhexidine. Limits are 6mg/kg.
