Abstract:
A process for reducing the viscosity of an aqueous surfactant composition comprising:(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 CH2CH2Oâ€”, CHCH3CH2Oâ€”, CH2â€”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.
