摘　　要：以月桂醇聚醚硫酸酯钠(AES)作为参照,比较了pH值对月桂酰肌氨酸钠、月桂酰丙氨酸、椰油酰谷氨酸二钠以及甲基椰油酰基牛磺酸钠4种氨基酸表面活性剂(AAS)泡沫性能的影响。考察AAS在替代AES时,对洗发水泡沫、絮凝、护色以及去皮脂性能的影响,并讨论了AAS结构与这些性能间的相关性。结果表明,与AES相比,月桂酰肌氨酸钠、月桂酰丙氨酸和椰油酰谷氨酸二钠泡沫性能受pH值影响较大,甲基椰油酰基牛磺酸钠的影响较小。在AES体系中复配AAS可以增强泡沫稳定性,复配甲基椰油酰基牛磺酸钠还可以显著提升发泡性能。4种AAS都可以延长体系产生絮凝的时间,椰油酰谷氨酸二钠的效果最为明显。椰油酰谷氨酸二钠和甲基椰油酰基牛磺酸钠的头发护色效果优于AES。椰油酰谷氨酸二钠对皮脂的清洁力弱于AES,月桂酰肌氨酸钠、月桂酰丙氨酸、椰油酰谷氨酸二钠对皮脂的清洁力均强于AES。Using sodium laureth sulfate(AES)as reference,the effects of different pH values on the foam properties of four amino acid surfactants(sodium lauroyl sarcosinate,lauroyl alanine,disodium cocoyl glutamate,sodium methyl cocoyl taurate)were compared.On the basis,the effects of amino acid surfactants on foam properties of shampoo,coacervation curves,color protection properties and sebum removal properties were studied,when sodium laureth sulfate was replaced by amino acid surfactant,and the correlation between the structure of amino acid surfactant and these properties was discussed.Compared with sodium laureth sulfate,the foam properties of sodium lauroyl sarcosinate,lauroyl alanine and disodium cocoyl glutamate were significantly affected by pH value,and sodium methyl cocoyl taurate was less affected.The foam stability of shampoo system can be enhanced by the combination of amino acid surfactant,and the foam performance of shampoo system can be significantly improved by the combination of sodium methyl cocoyl taurate.All the four amino acid surfactants can prolong the flocculation time of shampoo,and the effect of disodium cocoyl glutamate was the most obvious.The hair color protection effect of disodium cocoyl glutamate and sodium methyl cocoyl taurate was better than sodium laureth sulfate.The degreasing power of disodium cocoyl glutamate was weaker than that of sodium laureth sulfate,and the degreasing power of sodium lauroyl sarcosinate,lauroyl alanine and sodium methyl cocoyl taurate were stronger than that of sodium laureth sulfate.
