Abstract

Surface activities of four potassium N-acyl-N-methyl-${\beta}$-alaninate including surface tension, foaming power, foam stability, emulsifying power and dispersion power were measured respectively, and critical micelle concentration(cmc) was evaluated. Consequently these anionic surfactants with long chain acyl amide showed good emusifying power of O/W type, foaming, foam stability and dispersion effect.
