摘　　要：针对椰油酰谷氨酸钠、椰油酰丙氨酸钠、月桂酰肌氨酸钠、月桂酰天冬氨酸钠在洗发水中的应用性能进行对比研究,以月桂醇聚醚硫酸酯钠(SLES)为参考,从发泡性能、清洁能力、增稠性能和絮凝性能方面进行了讨论。通过实验得出,椰油酰丙氨酸钠和月桂酰肌氨酸钠的发泡性能略优于SLES;4种氨基酸表面活性剂的清洁能力差异不大,且都略好于SLES;增稠性能普遍低于SLES,通过添加增稠剂调整体系黏度,椰油酰丙氨酸钠体系黏度可以被提升至1500 Pa·s,其他3种氨基体系黏度依然低于1000 Pa·s;4种氨基酸表活的絮凝曲线比SLES缓和,说明氨基酸洗发水冲水较慢,而硫酸盐体系冲水略快。Four kinds of amino acid surfactants(sodium cocoyl glutamate,sodium cocoyl alaninate,sodium lauroyl sarcosinate and sodium lauroyl aspartate)were studied on their performance in shampoo.Taking sodium laureth sulfate(SLES)as a benchmark,the foaming performance,detergency,thickening effect and coacervation phenomena thereof were evaluated in shampoo.The results showed that the foaming performance of the systems containing sodium cocoyl alaninate and sodium lauroyl sarcosinate were a little better than that of SLES.In shampoo,all of the four amino acid surfactants had similar detergency which was a little better than that of SLES,while the behaviors in thickening and coacervation were not as good as SLES.But,the viscosity of the system containing sodium cocoyl alaninate could be increased to 1500 Pa·s by adding a thickening agent.The coacervation curves of these 4 amino acid surfactants in shampoo were smoother than that of SLES,which suggested that the rinse-off performance was slower than that of SLES.
