摘要
Abstract
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.关键词
