Abstract
The present invention relates to stable, homogeneous, preferably concentrated, aqueous liquid textile treatment compositions that contain biodegradable diester quaternary ammonium compounds of the formula: ##STR1## wherein each Q is --O--(O)C-- or --C(O)--O--; PA1 n is 1 to 4; PA1 each R.sup.1 substituent is a short chain C.sub.1 -C.sub.6 alkyl group, benzyl group or mixtures thereof; PA1 each R.sup.2 is a long chain C.sub.11 -C.sub.21 hydrocarbyl, or substituted hydrocarbyl substituent and the counterion, PA1 X.sup.-, can be any softener-compatible anion; PA1 wherein the biodegradable quaternary ammonium fabric softening compound is derived from C.sub.11 -C.sub.21 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% by weight, the aqueous compositions being stable without nonionic viscosity modifiers when the concentration is less than or equal to 13%.
