An easy determination of Kathon CG, an antimicrobial agent widely used in cosmetic and toiletry products, has been achieved by means of silicone membrane interfaced mass spectrometry. Low levels of the above preservative (up to p.p.b.) could be easily detected in both aqueous solutions and cosmetic emulsions. Valuable information has been obtained on the stabilization and decomposition processes to which the organic components of Kathon CG are subject. The role of magnesium ions, which are present as a stabilizing agent in Kathon CG formulation, in these processes has been investigated, leading to the identification of some degradation products.
通过硅胶膜接口质谱法已实现了对广泛用于化妆品和洗漱用品中的抗菌剂凯松CG（Kathon CG）的简易测定。在水溶液和化妆品乳液中均可轻松检测到低含量的上述防腐剂（高达十亿分之一）。已获得了有关凯松CG有机成分所经历的稳定化和分解过程的宝贵信息。对在凯松CG配方中作为稳定剂存在的镁离子在这些过程中的作用进行了研究，从而鉴定出了一些降解产物。
