摘要：

Natural Sea Beauty系列化妆品富含来自Dead Sea水中的矿物质,对皮肤有较好的治疗和滋养作用.本文采用毛细管区带电泳的技术,电迁移双端进样,5 mmol/L咪唑-2 mmol/L硝酸为背景电解质,以富马酸调至pH 4.1,UV间接测定法(214nm),在6min内同时检测了化妆品中的阴阳离子(K+、Na+、Ca2+、Mg2+、Cl-、Br-),与离子色谱法所得结果进行了对照.此方法可为鉴别不同品牌的化妆品提供一定的依据.

Abstract:

For thousands of years the extraordinary waters of the Dead Sea have healed and rejuvenated skin because of their unique mineral content. Natural Sea Beauty products use the power of these Dead Sea minerals. The capillary electrophoresis technique based on the electromigrative sample introduction from both ends of the capillary was applied for the simultaneous determination of inorganic anions and cations in the cosmetics of Natural Sea Beauty products. The optimized separations were carried out in 5 mmol/L imidazole and 2 mmol/L nitrate electrolyte neutralized with fumaric acid to pH 4.1, using indirect UV detection at 214 nm. Six inorganic ions (K+、Na+、Ca2+、Mg2+、Cl-、Br-) were well separated in less than 6 min. The comparison of the results with ion chromatography is presented. This method is one of ways used to test different produces.
