C. and the preheated aqueous solution of the glycose is metered with effective mixing into the reaction mixture of alcohol, acidic catalyst and emulsifier in such a manner that an emulsion is formed,(e) the reaction is carried out at from 100.degree. to 150.degree. C. and from 10 to 100 mbar, the water introduced into the reaction mixture and the water formed by the reaction being continuously removed by distillation,(f) after the reaction has ended, the acidic catalyst is neutralized by addition of a base such that the resulting mixture has a pH of 8-10, then(g) the excess alcohol is removed by distillation at from 0.01 to 10 mbar down to a residual content of less than 5% by weight, based on the amount of alkyl glycoside present, and(h) the reaction mixture is bleached at pH 8-10 after conversion into an aqueous paste having a content of from 30 to 70% by weight of alkyl glycoside using a compound eliminating active oxygen.
