Abstract (en)

[origin: WO9856496A1] A surfactant composition containing (a) from about 1 to about 40 % by weight of a sugar surfactant selected from the group consisting of a polyhydroxy fatty acid amide, an alkyl polyglycoside, and mixtures thereof; (b) from about 1 to about 40 % by weight of an anionic surfactant; (c) from about 0.1 to about 10 % by weight of an amphoacetate; and (d) remainder, water, all weights being based on the weight of the composition. The anionic surfactants are preferably selected from the group consisting of alkyl sulfate, alkyl ether sulfate, alkyl benzene sulfonate and mixtures thereof. The surfactant compositions are taught to be foaming and have foam stability.
