Application of low molecular organic compounds as viscosity regulators for highly viscous technical tenside concentrates

摘要

An aqueous anionic surfactant concentrate containing certain low molecular weight organic compounds as viscosity regulators and a method of regulating the viscosity of highly viscous concentrates, e.g. alpha -sulfo fatty acid ester surfactants in concentrations about 30% by weight. The viscosity regulators are selected from: (a) a C1-C6-alkyl monocarboxylic acid substituted in the alpha -position by a halogen, cyano or sulfo group, a salt thereof, or an ester thereof with a C1-C6-alkanol, (b) a C1-C6-alkylene dicarboxylic acid substituted in the alpha -position by a halogen, cyano or sulfo group, a salt thereof, or an ester thereof with a C1-C6-alkanol, (c) nitrilotriacetic acid and its salts, (d) an ether alcohol containing from 2 to 4 alkylene glycol units and 1 alkoxy group, (e) and mixtures thereof.
