MIXTURES OF HIGHLY CONCENTRATED FLUID ANIONIC SURFACTANTS

摘要

Mixtures of highly concentrated aqueous anionic surfactants having a solids content of 50 to 80% by weight containing - based on the proportion of surfactant - a) 60 to 90% by weight of alkyl ether sulfates of formula (I), wherein R1 represents a linear or branched alkyl radical having from 12 to 22 carbon atoms, n represents a number from 1 to 10 and X1 represents an alkali metal, an alkaline earth metal, ammonium, an alkylammonium, an alkanol ammonium or glucammonium, andb) 10 to 40% by weight of alkyl sulfates of formula (II), R2 OSO3 X2 wherein R2 represents a linear or branched alkyl radical having 12 to 22 carbon atoms, and X2 represents an alkali metal, an alkaline earth metal, ammonium, an alkylammonium, an alkanol ammonium or glucammonium, provided that the quantitative indications are complementary at 100% by weight with l if necessary, other surfactants. / P
