Abstract (en)
[origin: WO9502390A1] According to one aspect of the present invention there is provided an anionic surfactant system containing: (a) alkyl sulfate surfactant derived from natural sources comprising a mixture of alkyl chain lengths wherein the weight distribution of the alkyl chain lengths is such that less than 20 % by weight of the alkyl chain lengths are C12, from 30 % to 80 % by weight of the alkyl chain lengths are C14, from 30 % to 50 % by weight of the alkyl chain lengths are C16 and less than 10 % by weight of the alkyl chain lengths are C18. Said anionic surfactant system preferably also contains alkyl ethoxysulfate surfactant. Said alkyl ethoxysulfate surfactant is preferably a water soluble C12-C18 alkyl ethoxysulfate salt containing an average of from 1 to 7 ethoxy groups per mole derived from the condensation product of a C12-C18 alcohol wherein said C12-C18 alcohol is most preferably derived from a natural source.
