Abstract

Described is a process for preparing mixtures of mixed-alkylated methylolated 4,5-dihydroxyimidazolidin-2-ones by reaction of methylolated 4,5-dihydroxyimidazolidin-2-one (DMDHEU) with a monohydric C.sub.1-5 alcohol and a polyol selected from the group consisting of ethylene glycol, diethylene glycol, 1,2-propylene glycol, 1,3-propylene glycol, 1,2-butylene glycol, 1,3-butylene glycol, 1,4-butylene glycol, glycerol and polyethylene glycols of the formula HO(CH.sub.2 CH.sub.2 O).sub.n H where 3.ltoreq.n.ltoreq.20, the monohydric C.sub.1-5 alcohol and the polyol each being used in an amount of from 0.1 to 2.0 mol equivalents, based on DMDHEU, and the reaction being carried out at temperatures from 20.degree. C. to 70.degree. C. and at a pH of from 1 to 2.5, and the pH being set to a value of from 4 to 8 after the reaction.
