ABSTRACT:
Processes for preparing light-colored alkyl and/or alkenyl oligoglycoside mixtures are disclosed. The processes disclosed include providing an initial mixture of an alk(en)yl oligoglycoside and a rheology-modifying agent, the mixture having 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 alk(en)yl oligoglycoside; and bleaching the initial mixture 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 alk(en)yl oligoglycoside. Also disclosed is the use of such mixtures in cleaning compositions, such as detergents, washing and dishwashing compositions.
