Claim 1

A liquid fabric softener concentrate in the form of an isotropic solution comprising (a) from about 20% to about 75% of substantially water-insoluble cationic fabric softener, at least about 70% of said fabric softener consisting of one or more components together having a melting completion temperature (T c ) of less than 20° C. (b) from about 3% to about 75% of substantially water-insoluble nonionic extender selected from the group consisting of C 10 -C 40 linear and branched hydrocarbons and esters of mono- and polyhydric alcohols with C 8 -C 24 fatty acids, and (c) from about 10% to about 77% of water-miscible organic solvent, wherein the cationic fabric softener, nonionic extender and organic solvent constitute in total at least about 50% of the concentrate and wherein Component (a) is selected from the following compounds or mixtures thereof: ammonium compounds of formula ##STR6## wherein R 1 and R 2 independently represent linear or branched chain alkyl or alkenyl groups of from about 16 to about 24 carbon atoms, R 3 and R 4 independently represent hydrogen or alkyl or alkenyl groups of from 1 to about 4 carbon atoms, and X is a salt counterion, wherein the ammonium compound has an iodine value greater than about 40, alkoxylated compounds of formula ##STR7## wherein R 1 and R 2 independently represent linear or branched chain alkyl or alkenyl groups of from about 16 to about 24 carbon atoms, R 5 and R 6 independently represent alkyl or alkenyl groups of from 1 to about 4 carbon atoms or a group of formula (C n H 2n O) m H wherein n is 2 or 3 and m is from 0 to about 15, provided that the total number of C n H 2n O groups is from 1 to about 20 and wherein the alkoxylated ammonium compound has an iodine value greater than about 20, imidazolinium compounds of formula ##STR8## wherein R 1 and R 2 independently represent linear or branched chain alkyl and/or alkenyl groups of from about 16 to about 24 carbon atoms, R 3 and R 4 independently represent hydrogen, alkyl, alkenyl or hydroxyalkyl groups of from 1 to about 4 carbon atoms, and X is a salt counterion, wherein the imidazolinium compound has an iodine value greater than about 40.
