High-concentration flowable anionic surfactant mixtures containing alkyl ether sulfates and alkyl sulfates

摘要

A high-concentrate flowable liquid anionic surfactant composition containing: (a) from 60 to 90% by weight of an alkyl ether sulfate corresponding to formula I:; $PTEXTPDATR/PDATHILSPPDAT1/PDAT/SP/HILPDATO(CH/PDATHILSBPDAT2/PDAT/SB/HILPDATCH/PDATHILSBPDAT2/PDAT/SB/HILPDATO)/PDATHILSBPDATn/PDAT/SB/HILPDATSO/PDATHILSBPDAT3/PDAT/SB/HILPDATX\ \ (I)/PDAT/PTEXT$ ;wherein R¹ is a linear or branched alkyl radical having from 12 to 22 carbon atoms, n is a number having a value of from 1 to 10, and X is an alkali metal, alkaline earth metal, ammonium, alkylammonium, alkanolammonium or glucammonium; and (b) from 10 to 40% by weight of an alkyl sulfate corresponding to formula II:; $PTEXTPDATR/PDATHILSPPDAT2/PDAT/SP/HILPDATOSO/PDATHILSBPDAT3/PDAT/SB/HILPDATX\ \ (II)/PDAT/PTEXT$ ;wherein R² is a linear or branched alkyl radical having from 12 to 22 carbon atoms, and X is an alkali metal, alkaline earth metal, ammonium, alkylammonium, alkanolammonium or glucammonium, all weights being based on the total weight of the composition, and wherein the composition has a solids content of from 50 to 80% by weight.
