Abstract

Process for the production of aqueous storable nonionic surfactants in which crystallization moderators selected from the group consisting of a) alkyl glycosides based on short-chain primary alcohols, b) alkyl glycosides based on Guerget alcohols, c) glycosides based on polyols, d) short-chain primary alcohols, e) fatty alcohol polyglycol ethers, f) polyethylene glycols, g) glucose and h) iron(III) ions are added to aqueous preparations containing alkyl and/or alkenyl glycosides corresponding to formula (I): EQU R.sup.1 O--(G).sub.P (I) in which R.sup.1 is a linear alkyl and/or alkenyl radical containing 6 to 22 carbon atoms, G is a sugar unit containing 5 or 6 carbon atoms and p is a number from 1 to 10.
