Introduction

The test substances of this standard are chloroacetaldehyde, 2,4-dihydroxy-3-methylbenzaldehyde, crotonaldehyde, acetophenone and 2-pentylenecyclohexanone. Prohibited substances specified in the Cosmetic Safety Technical Specification (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. This standard only provides testing methods for the determination of these substances in cosmetics. Chloroacetaldehyde, 2,4-dihydroxy-3-methylbenzene in cosmetics Formaldehyde, crotonaldehyde, acetophenone, 2-pentylenecyclohexanone, Determination of glutaraldehyde content by high performance liquid chromatography

1 Scope

This standard specifies chloroacetaldehyde, 2,4-dihydroxy-3-methylbenzaldehyde, crotonaldehyde, acetophenone, 2-pentylenecyclohexanone and pentane in cosmetics. Principles, reagents and materials, equipment, test procedures, calculation of results, recovery and precision of aldehydes for high performance liquid chromatography Poor content. This standard applies to water, cream, lotion, powder and wax-based cosmetics in chloroacetaldehyde, 2,4-dihydroxy-3-methylbenzaldehyde, Pakistan Determination of soybean aldehyde, acetophenone, 2-pentylene cyclohexanone and glutaraldehyde. The detection limits and limits of quantitation of this standard. chloroacetaldehyde, 2,4-dihydroxy-3-methylbenzaldehyde, acetophenone, 2-pentylenecyclohexanone and pentane The detection limit of aldehyde method was 1.0mg/kg, the limit of quantification was 3.0mg/kg; the detection limit of crotonaldehyde was 0.5mg/kg, the limit of quantification was 1.5 mg/kg.

2 Normative references

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

3 Principle

Water, cream, lotion and powder cosmetic samples are directly extracted with 50% (volume fraction) acetonitrile solution; wax-based cosmetic samples Disperse with n-hexane and extract with 50% (volume fraction) acetonitrile solution; the extract is centrifuged, filtered, and determined by high performance liquid chromatography. (wherein chloroacetaldehyde and glutaraldehyde are determined by high performance liquid chromatography after being derivatized with 2,4-dinitrophenylhydrazine). According to retention time and light Spectral qualitative, external standard method quantitative. If necessary, confirm by high performance liquid chromatography-mass spectrometry/mass spectrometry.

4 reagents and materials

Unless otherwise stated, the reagents used were of analytical grade and the water was the first grade water specified in GB/T 6682. 4.1 Acetonitrile. Chromatographically pure. 4.2 Hexane. Chromatographically pure. 4.3 Sodium dihydrogen phosphate (NaH2PO4·2H2O). 4.4 Phosphoric acid. 4.5 2,4-Dinitrophenylhydrazine. the purity is not less than 99%. 4.6 50% Acetonitrile Solution. Accurately measure 100 mL of acetonitrile (4.1) mixed with 100 mL of water. 4.7 Buffer solution. Accurately weigh 15.6 g of sodium dihydrogen phosphate (4.3), dissolve in water and dilute to 1 L, and adjust the pH to 2.0 with phosphoric acid (4.4). 4.8 2,4-Dinitrophenylhydrazine solution (4.0g/L). accurately weigh 2,4-dinitrophenylhydrazine (4.5) 2.0g, dissolved in acetonitrile (4.1) and made up to ......
