| 摘要 |
Alkali metal alkane sulfonates containing on averge 11 to 21 carbon atoms are used as viscosity regulators for aqueous, highly concentrated commercial anionic surfactant concentrates, more especially for alpha -sulfofatty acid ester salt concentrates containing at least 30% by weight of alpha -sulfofatty acid ester salt. The viscosity regulators are used in quantities of from 0.5 to 10% by weight, based on the surfactant content, so that the concentrates have a viscosity at 40 DEG C. of at most 10,000 mPas. |
