Low-foaming, silicone-free, aqueous textile auxiliaries, their preparation and their use

摘要

Low-foaming, silicone-free, aqueous textile auxiliaries are described which are characterised in that they comprise (a) a reaction product of a nonionic surfactant of the formula in which R denotes an aliphatic radical having at least 8 carbon atoms, R1 denotes hydrogen, C1- to C8-alkyl, a cycloaliphatic radical having at least 5 C atoms, lower alkylphenyl or styryl, "Alkylen" denotes an alkylene radical of 2 to 4 carbon atoms and p denotes a number from 2 to 60, with a compound containing an acid water-solubilising group, (b) a nonionic surfactant of the formula (1) and, if desired, (c) a hydrotropic agent. The textile auxiliaries are suitable as dispersants and for the wetting and/or washing of fibre materials.
