| Abstract: | The amphoteric surfactant,{N,N-Bis-2-hydroxyl,3-(N',N'-dimethyl,N'-tetra decyl)amino]propyl}glycine dichloride is synthesized by the reaction of glycine,epoxy chloropropane,and N,N-dimethyldodecylamine via two steps.The reaction factors of pH and temperature are investigated,and then the properties of resulting products involving foamability,foam stability,and compatibility are measured.The experiment results show that the best reaction condition is that PH value ranges from 9 to 10,and temperature ranges from 60 to 70 ℃.Foamability,foam stability and surface activity of the product are good,and the compatibility with other components of shampoo is also very good. |
