摘要： 研究了月桂酰肌氨酸钠(LS)与非离子型、阴离子型以及两性离子型表面活性剂的复配体系。通过改变表面活性剂用量、配比等参数,发现对于二元复配体系,少量烷基糖苷(APG)即可实现协同增稠;而在三元复配体系中,配比对体系黏度影响极大,其中LS、椰油酰胺丙基甜菜碱(CAB)和APG复配能实现较好的自增稠效果。当在复配体系中CAB质量不低于LS时,复配体系黏度≥3 000 mPa·s,市场上流行的无硅油无硫酸盐类洗发产品可以借鉴此类自增稠方案。

Abstract: The systems of sodium lauroyl sarcosinate (LS) mixed with nonionic,anionic,and zwitterionic surfactants were studied.By changing the amount and the mixing ratios of these surfactants,it was found that,as for binary systems,synergistic thickening could be achieved by adding a small amount of alkyl polyglucoside (APG).In ternary systems,the mixing ratios of surfactants had significant influences on viscosity,and a self-thickening system of LS/cocamidopropyl betaine (CAB)/APG could be obtained.The viscosity of the mixture was no less than 3 000 mPa·s when the mass of CAB was not lower than LS.The popular silicone- and sulfate-free shampoos can use this self-thickening formulation as a reference.

Key words: surfactant, sodium lauroyl sarcosinate, self-thickening, silicone- and sulfate-free
