Determination of 21 sulfonamides in cosmetics by high performance liquid chromatography method ICS 71.100.70 Y42 National Standards of People's Republic of China Determination of cosmetics twenty-one kinds of sulfonamides High Performance Liquid Chromatography Posted 2009-11-30 2010-05-01 implementation Administration of Quality Supervision, Inspection and Quarantine of People's Republic of China Standardization Administration of China released ForewordThe Standard Appendix A, Appendix B is an informative annex. The standard proposed by China National Light Industry Council. This standard by the National Standardization Technical Committee of Fragrance Flavor and Cosmetic (SAC/TC257) centralized. This standard is drafted by. China Inspection and Quarantine Science Research Institute, Shanghai Daily Chemical Industry Research Institute, Shanghai Institute of spices. The main drafters of this standard. Ma Qiang, Zhang, Wang Chao, Xiao Haiqing, Wu Ting Kang Wei, Cui Jian Jie.IntroductionThe standard test substance is banned substances of "Hygienic Standard for Cosmetics" shall consist of not as a cosmetic raw material, component Added to cosmetics. If technically unavoidable banned substances as impurities into cosmetics, the finished cosmetic products should follow the "Cosmetics Health standards "General requirements for cosmetics, that is, under normal and reasonably foreseeable conditions of use, should not cause harm to human health. At present, China has not yet specified the substance of limited value, the present standards, the determination of these substances in cosmetics only provide detection methods. Determination of cosmetics twenty-one kinds of sulfonamides High Performance Liquid Chromatography1 ScopeThis standard specifies a high performance liquid chromatographic method cosmetics twenty-one kinds of sulfonamides. This standard applies to the determination of cosmetics twenty-one kinds of sulfonamides. The standard detection and quantitation limits. sulfa guanidine, sulfonamides, sulfacetamide, of sulfonamide sulfadiazine, Sulfathiazole, sulfonamides topiramate Piperidine, sulfamethyldiazine, sulfamethazine triazole, sulfamethazine, among sulfadimethoxine, sulfa quinoline morpholine, and the detection limit was sulfanitran 0.2mg/kg, the limit of quantification of 0.6mg/kg; sulfamethoxazole thiadiazole sulfa methoxy pyridazine, succinyl Sulfathiazole, sulfa chlorine pyridazine, sulfamethoxazole Isobutyl yl, among methoxy pyrimidine sulfonamides, o-methoxy pyrimidine sulfonamides, sulfamethazine different azole detection limit of 0.4mg/kg, the limit of quantification 1.2mg/kg.2 Normative referencesThe following documents contain provisions which, through reference in this standard and become the standard terms.
