Abstract
Abstract Disclosed is a liquid fine washing agent, which, in addition to good washing properties, has an excellent fiber-caring effect and, in particular, bestows a soft feel to textiles treated therewith. The washing agent achieving these objectives contains about 7 to 40% by weight of at least one nonionic surface-active agent, especially at least one C 10 -C 20 -alkylpolyglycol ether and/or C 6 -C 20 -alkylphenolpolyglycol ether; about 3 to 15% by weight of at least one C 8 -C 20 fatty acid polyglycol diester; and about 1 to 7% by weight of a quaternary ammonium compound with textile-softening properties, especially a di-C 10 -C 22 -alkyldimethyl or - ethylammonium halide.
