ALKYL SULFATES AS VISCOSITY MODIFIERS IN ANIONIC SURFACTANT COMPOSITIONS

摘要

A method for adjusting the viscosity of anionic surfactant compositions is provided by combining anionic surfactant compositions with a viscosity modifier comprising alkyl sulfates of the formula: R-OSO3M in which R is a straight or branched chain alkyl of from 7 to 10 carbons and M is an alkali metal. The viscosity modifier increases the salt tolerance levels of the anionic compositions without reducing peak viscosity.
