Foam performance of the compatible system of two ammonium anionic surfactants,alkyl monoethanolamide,alkyl diethanolamide and so on was studied in different water hardness. The foaming influence of emulsified silicone, lanolin,stearyl alcohol,pearlizing,fragrance,cationic surfactants and polymerized cationic compound and other additives were described. It was shown that the foaming stability in all the lab's systems was good. The foaming power became stronger when LSA was combined with AESA,in which the con...
