PROCESS FOR PREPARING AQUEOUS SOLUTIONS OF ANIONIC SURFACTANTS WITH IMPROVED LOW-TEMPERATURE STABILITY

摘要

Aqueous solutions of anionic surfactants with an improved low-temperature stability are obtained when one adds to them mixtures of nonionic surfactants containing: a) alkyl and/or alkenyl oligoglycosides of the formula (I): R<1>-O-[G]p in which R<1> stands for an alkyl and/or alkenyl group with 6-22 carbon atoms, G for a sugar group with 5 or 6 carbon atoms and p for a number from 1 to 10, b) fatty alcohol polyglycol ethers of formula (II), in which R<2> stands for an alkyl group with 8-11 carbon atoms, n for a number from 4 to 9 and m for 0 or a number from 1 to 3, and, as needed, c) fatty alcohol polyglycol ethers of formula (III),in which R<3> stands for an alkyl group with 12-15 carbon atoms, n for a number from 4 to 9 and m for 0 or a number from 1 to 3. The products are preferably used in the production of hand dish-washing detergents.
