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&#xb0; 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&#xb0; 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.

Processes for preparing light-colored alk(en)yl oligoglycoside mixtures

A laundry detergent composition containing a surfactant system having: (a) an alkyl and/or alkenyl oligoglycoside; (b) from about 5 to 35% by weight of a fatty alcohol; and (c) up to 2% by weight water, all weights being based on the weight of the surfactant system.
