| Abstract: | Lauroylamidopropyl betaine was synthesized with N,N dimethyl N ′ lauroyl 1,3 propylenediamine and sodium chloroacetate.The optimum reaction conditions were investigated by changing reaction temperature,reaction time and acidity of sodium chloroacetate,and the properties of the product such as foamability,foam stability and thickness were studied.Thus, when reaction temperature was 70 ℃,reaction time was 5 h,and pH of sodium chloroacetate was 6 0, the active material content of the product had the highest value of (30 0±1 6)% foamability,foam stability and thickness of product were all good,and the compatibility of lauroylamidopropyl betaine with other components of shampoo was excellent. |
