Determination of phthalate esters in cosmetics ICS 71.100.70 Y42 National Standards of People's Republic of China Replace GB/T 28599-2012 Determination of phthalates in cosmetics 2020-09-29 released 2021-01-01 implementation State Administration for Market Regulation Issued by the National Standardization Management Committee

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard replaces GB/T 28599-2012 "Determination of Phthalate Substances in Cosmetics", and is consistent with GB/T 28599-2012 The main technical changes are as follows. ---The scope of application of the standard has been revised, and the matrix types of cosmetics applicable to the three measurement methods have been improved. The second method (high performance liquid chromatography) Spectroscopy) removed the base of nail polish cosmetics; in addition, the first method (gas chromatography-mass spectrometry) and the second method (high performance liquid Chromatography) The determination of target substances has increased from 22 to 24, and the third method (gas chromatography) has increased the determination of target substances from 18 Increase to 24 types; ---Modified the sample preparation process and measurement conditions in the standard analysis step; ---Modified the detection limit and quantification limit of the standard first method (gas chromatography-mass spectrometry), unified the second method (high performance liquid chromatography) Method) The detection limits and quantification limits of different cosmetic bases. This standard was proposed and managed by the National Standardization Technical Committee on Inspection Methods for Key Products of Quality Supervision (SAC/TC374). Drafting organization of this standard. Beijing Food Safety Monitoring and Risk Assessment Center (Beijing Food Inspection Institute)/National Cosmetics Quality Supervision Inspection Center (Beijing), CCIC Warner (Beijing) Quality Technology Center Co., Ltd., Warner Pass (Beijing) Certification Co., Ltd., Shanghai Quality Institute of Supervision and Inspection Technology, Guangzhou Institute of Quality Supervision and Inspection, Yujiahui Co., Ltd., Guangzhou Jintong Biotechnology Co., Ltd., Mei (Guangdong) Commodity Co., Ltd.

The previous versions of the standard replaced by this standard are as follows. ---GB/T 28599-2012. Determination of phthalates in cosmetics

1 Scope

This standard specifies the gas chromatography-mass spectrometry (GC/MS), high performance liquid chromatography of phthalate substances in cosmetics (HPLC) and gas chromatography (GC) determination methods. This standard applies to the determination of phthalate substances in cosmetics. The first method of gas chromatography-mass spectrometry is applicable to The determination of 24 phthalate substances in liquids, perfumes, creams, lotions, gels, essential oils, nail polishes, and solid cosmetics is an arbitration law; The second method HPLC method is applicable to 24 kinds of phthalate esters in water, perfume, cream, lotion, gel, essential oil and solid cosmetics Determination of substances; the third method gas chromatography is applicable to 24 kinds of liquids, perfumes, creams, lotions, gels, essential oils, nail polishes, and solid cosmetics Determination of phthalates.
