<p>The present invention relates to stable, homogeneous, preferably concentrated, aqueous liquid textile treatment compositions. The compositions of the present invention contain biodegradable diester quaternary ammonium compounds of formula (I), wherein: each Q is -O-(O)C- or -C(O)-O-; n is 1 to 4; each R1 substituent is a short chain C1-C6 alkyl group, benzyl group or mixtures thereof; each R2 is a long chain C11-C21 hydrocarbyl, or substituted hydrocarbyl substituent and the counterion, X-, can be any softener-compatible anion; wherein the biodegradable quaternary ammonium fabric softening compound is derived from C11-C21 fatty acyl groups having an Iodine Value of from greater than about 5 to less than about 100, a cis/trans isomer weight ratio of greater than about 30/70 when the Iodine Value is less than about 25, the level of unsaturation of the fatty acyl groups is less than about 65 percent by weight, the aqueous compositions being stable without nonionic viscosity modifiers when the concentration is less than or equal to 13 percent.</p> |
