The present invention relates to fabric enhancer compositions as well as the methods of making and using same. Such fabric enhancer compositions comprise a quaternary ammonium ester fabric softening active, a branched, ethoxylated nonionic surfactant and perfume. Such fabric enhancer compositions exhibit improved freeze-thaw stability while also delivering the softening benefits that are desired by consumers. 2. A fabric enhancer composition according to wherein said fabric softening active quaternary ammonium ester has the following formula:{'br': None, 'sup': 2', '+', '1', '−, 'sub': 4-m', 'm, '{R—N—[X—Y—R]}A'} m is 1, 2 or 3 with proviso that the value of each m is identical;', {'sup': '1', 'each Ris independently hydrocarbyl, or substituted hydrocarbyl group;'}, {'sup': '2', 'sub': 1', '3, 'each Ris independently a C-Calkyl or hydroxyalkyl group;'}, {'sub': 2', '2', '3', '3', '2, 'each X is independently (CH)n, CH—CH(CH)— or CH—(CH)—CH— and'}, 'each n is independently 1, 2, 3 or 4;', 'each Y is independently —O—(O)C— or —C(O)—O—;', 'A− is independently selected from the group consisting of chloride, methylsulfate, ethylsulfate, and sulfate;', {'sup': '1', 'with the proviso that the sum of carbons in each R, when Y is —O—(O)C—, is from 13 to 21.'}], 'wherein3. A fabric enhancer composition according to wherein said quaternary ammonium ester fabric softening active comprises a fatty acid moiety comprising 12 to 22 carbons claim 1 , said quaternary ammonium esters being selected from the group consisting of:a) bis-(2-hydroxypropyl)-dimethylammonium methylsulfate fatty acid ester;b) isomers of bis-(2-hydroxypropyl)-dimethylammonium methylsulfate fatty acid ester;c) N,N-bis(hydroxyethyl)-N,N-dimethyl ammonium chloride fatty acid ester;d) N,N-bis(hydroxyethyl)-N,N-dimethyl ammonium methylsulfate fatty acid ester; ande) N,N,N-tri(2-hydroxyethyl)-N-methyl ammonium methylsulfate fatty acid ester;said quaternary ammonium ester fabric softening active's fatty acid ester ...
