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 by Dalian Food Inspection Institute, Dalian City Product Quality Inspection Institute, Shanghai Institute of Daily Chemical Industry.

Introduction
The standard test substance is China's "Cosmetic Safety Technical Code" Prohibited 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
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 13 prohibited colorants in cosmetics
High performance liquid chromatography
1 Scope
This standard specifies the cosmetics 13 kinds of prohibited colorants (Acid Yellow 36, Acid Violet 49, Pigment Red 53, Solvent Red 49, Basic Violet 1, points
Sanhuang 3, Basic Violet 3, Pigment Orange 5, Sudan I, Sudan II, Solvent Blue 35, Sudan IV, Basic Violet 10)
And its mass spectrometry method.
This standard applies to lipstick and other wax-based category, nail polish, cosmetics and other cosmetics in the banned 13 quantitative determination.
The detection limit of 13 kinds of prohibited colorants in this standard and the quantitative limits see Table A.1.

GB/T 6682 analytical laboratory water specifications and test methods
3 method summary
The sample to be tested is dispersed in tetrahydrofuran, then a methanol-water mixed solution containing ammonium acetate is added, the target substance is extracted by ultrasound, centrifuged and filtered
After using reversed-phase high performance liquid chromatography, diode array detection, standard curve external standard method. Liquid chromatography identified positive samples
Confirmed by high performance liquid chromatography tandem mass spectrometry (HPLC-MS/MS).
4 Reagents and materials
Unless otherwise indicated, the reagents used are of analytical grade, the water used is a water GB/T 6682 provisions.
4.1 The name of the standard substance (English name), CI number, CAS number, molecular formula, molecular structure, relative molecular mass, purity shown in Table B.1.
4.2 Tetrahydrofuran.
4.3 methanol.
4.4 Methanol-tetrahydrofuran (1 1) solution Tetrahydrofuran and methanol (4.3) were mixed at a ratio of 1 1 (VV).
4.5 methanol. Chromatographic pure, for the mass spectrometry confirmed the preparation of the mobile phase.
4.6 acetonitrile. Chromatographic purity.
4.7 Ammonium acetate. Chromatographic purity.
4.8 Formic acid. Chromatographic purity.
4.9 methanol - ammonium acetate aqueous solution Take ammonium acetate 0.77g, was added to 100mL water to fully dissolve, then add methanol (4.3) 100mL, charge
Points and mix well to prepare a solution of ammonium acetate concentration of 50mmol/L aqueous solution of methanol - ammonium acetate.
4.10 Preparation of standard stock solution Weigh pigment Orange 5, Disperse Yellow 3 10mg (accurate to 0.1mg), respectively, with tetrahydrofuran and methanol
After dissolving, dilute to 50mL to prepare a standard stock solution with a concentration of 0.2mg/mL. Weigh each of Pigment Red 53 and Sudan IV
10mg (accurate to 0.1mg) were dissolved in dimethyl sulfoxide and tetrahydrofuran, the volume to 10mL, formulated at a concentration of 1mg/mL
Standard stock solution. Weigh the remaining eight kinds of standard material (except Pigment Orange 5, Disperse Yellow 3, Pigment Red 53, Sudan Ⅳ, Alkali violet 10)
