Use of alkoxylated carboxylic acid esters for reducing viscosity of aqueous surfactant systems

摘要

A process for reducing the viscosity of an aqueous surfactant composition involving: (a) providing an aqueous surfactant composition containing at least one surfactant, other than an alkoxylated carboxylic acid ester; (b) providing a viscosity-reducing agent corresponding to formula (I):wherein R1CO is an aliphatic acyl group containing from 6 to 18 carbon atoms, AlkO represents CH2CH2O-, CHCH3CH2O-, CH2-CHCH3O, n is a number from 3 to 15, and R2 is an aliphatic alkyl group having from 1 to 22 carbon atoms; and (c) adding a viscosity-reducing effective amount of the viscosity-reducing agent to the aqueous surfactant composition.
