Patent ID: 6903066

Claim:
A process for preparing light-colored surfactant mixtures, said process comprising: (a) providing an initial mixture comprising (i) at least one surfactant selected from the group consisting of alkyl oligoglycosides and alkenyl oligoglycosides, and (ii) a rheology-modifying agent; wherein the initial mixture has a viscosity of from 10 to 1000 mPas at a temperature of from 85 to 130° C., and a water content of less than 2% by weight, based on the at least one surfactant; and (b) bleaching the initial mixture comprising the at least one surfactant and the rheology-modifying agent at a temperature of from 85 to 130° C. to form a light-colored surfactant mixture having a water content of less than 2% by weight, based on the at least one surfactant.
