Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard was proposed by the China National Light Industry Council. This standard is under the jurisdiction of the National Standardization Technical Committee for Fragrance, Flavor and Cosmetics (SAC/TC257). Drafting organizations of this standard. Shandong Institute of Product Quality Inspection, Shandong Furui Da Biological Engineering Co., Ltd., Shanghai Daily Chemical Industry Industry Research Institute, Qingdao Jie Lixing Consulting Co., Ltd. The main drafters of this standard. Zhou Lili, Hou Guangyue, Bian Yingfang, Wang Yicun, Liu Qian, Yang Suzhen, Zou Huiling, Shen Min, Zhang Peng, Wang Xiaoxia, Ding Huan.

Introduction

The tested substances in this standard are prohibited substances stipulated in my country's "Safety Technical Specifications for Cosmetics (2015 Edition)". Prohibited substances refer to substances that cannot be added to cosmetics as raw materials or components in cosmetics production. "Cosmetic Safety Technical Specification (2015 Edition)'' stipulates. If it is technically unavoidable that prohibited substances are brought into cosmetics as impurities, the limited amount of national regulations shall comply with its regulations. If the limit is not specified, a safety risk assessment should be carried out to ensure that no harm to human health is allowed under normal, reasonable and foreseeable use conditions. Health hazards. At present, my country has not stipulated the limit value of this substance. The formulation of this standard only provides detection methods for the determination of this substance in cosmetics. Determination of para-red, a prohibited substance in lip cosmetics High performance liquid chromatography

1 Scope

This standard specifies the principles, reagents and materials, instruments and equipment, and tests for the determination of para-red in lip cosmetics by high performance liquid chromatography. Steps, calculation of results, recovery rate and precision, tolerance, etc. This standard applies to the determination of para-red in lip cosmetics such as lipstick, lip balm, lip glaze, lip gloss and lip gloss. The detection limit of this standard method is 0.20mg/kg, and the limit of quantification is 0.60mg/kg.

2 Normative references

The following documents are indispensable for the application of this document. For dated reference documents, only the dated version applies to this article Pieces. For undated reference documents, the latest version (including all amendments) is applicable to this document. GB/T 6682 Analytical laboratory water specifications and test methods

3 Principle

After the sample is dispersed in chloroform, it is extracted with acetonitrile, and after centrifugation through the membrane, it is measured by high performance liquid chromatography, and the external standard is legal the amount. When necessary, use liquid chromatography-mass spectrometry to confirm.

4 Reagents and materials

4.1 Water. Grade 1 water specified in GB/T 6682. 4.2 Para-red standard product. the purity is not less than 98%, the English name, CAS number, molecular formula, relative molecular mass and structural formula of para-red See Appendix A, Table A.1. 4.3 Trichloromethane (CHCl3). pure superior grade. 4.4 Acetonitrile (CH3CN). chromatographically pure. 4.5 Mobile phase. acetonitrile water = 85 15 (volume ratio). 4.6 Standard working solution. accurately weigh out para red standard (4.2) 5.00 mg (accurate to 0.01 mg) into a 10 mL volumetric flask, and add approximately 2mL of chloroform (4.3), after dissolving, use acetonitrile (4.4) to make a constant volume to prepare a para-red standard stock solution with a mass concentration of 500μg/mL (in Store at 4°C protected from light, valid for 3 months). Measure an appropriate amount of para-red standard stock solution, and dilute it with mobile phase (4.5) to mass concentrations respectively 0.10μg/mL, 0.20μg/mL, 0.50μg/mL, 1.00μg/mL, 2.00μg/mL, 5.00μg/mL, 10.00μg/mL Used as a liquid, ready to use.
