Abstract: Stable and homogeneous aqueous formulations of surfactants with an HLB of less than or equal to 13, which additionally contain a compound of the formula I in which R is C1-C8-alkyl, C1-C8-alkenyl, phenyl, alkylphenyl or phenalkyl with, in each case, 1 to 4 C atoms in the alkyl chain or cyclohexyl, R is hydrogen, or one of the radicals mentioned for R or R and R together with the N atom denote a heterocyclic radical, M is an alkali metal or ammonium cation or an equivalent of an alkaline earth or aluminium cation, and m and n are each, independently of one another, numbers from 6 to 8. The presence of the compounds of the formula I makes it possible to prepare stable and homogeneous aqueous formulations even of those surfactants which are otherwise only sparingly soluble or even insoluble in water.

Abstract: In the process described for the preparation of alkoxylates having a narrow distribution of homologs by reaction of compounds containing at least one hydroxyl group with alkylene oxide, complex compounds of antimony pentahalide with a special Lewis base are used as the catalysts. Alkoxylates having a narrow distribution of homologs and good color quality are obtained at a high conversion.
