摘　　要：为解决油菜油酰胺丙基二甲胺中和剂种类局限问题,以有机酸为质子化试剂制备阳离子型O/W乳化体系,并对系列样品进行了稳定性和表观粘度测试及液晶表征和功效评价。结果显示,与小分子氨基酸中和剂天冬氨酸和谷氨酸相比,使用甘醇酸、葡糖酸内酯、杏仁酸等有机酸中和得到的乳化体系在离心稳定性、长期稳定性、液晶结构的密集度和规整性以及去角质功效表现均更佳,且安全无刺激。研究结果表明,用有机酸中和油菜油酰胺丙基二甲胺构建的乳化体系思路对功效型液晶化妆品开发具有一定的指导意义。In order to solve the problem of limited types of brassicamidopropyl dimethylamine neutralizer,organic acids were selected as protonation reagents to prepare new cationic O/W emulsification systems,which also were used to conduct stability and viscosity tests,liquid crystal characteristics and efficacy evaluation.The results showed that compared with aspartic and glutamic acid protonation reagents,the emulsification systems containing glycolic acid,gluconolactone,mandelic acid presented better performances in terms of centrifugal and long-term stability tests,liquid-crystal display and exfoliation.The study demonstrated that combining organic acid and brassicamidopropyl dimethylamine to build a mild cationic emulsification system with strong exfoliating and anti-inflammatory effects has great significance for cosmetics development.
