Rinse-added fabric softening compositions are provided comprising mixtures of a substituted imidazoline fabric softener material and a highly ethoxylated hydrophobic material as a scum dispersant to prevent the formation of scum by interaction of the substituted imidazoline fabric softener material with anionic detergent surfactant and/or phosphate detergency builder entrapped in the fabric, and a liquid carrier. These, preferably biodegradable, compositions have good product stability, dispersibility, and concentratability, as well as excellent fabric softening characteristics.

Fabric softening compositions containing mixtures of substituted

The present invention relates to softening compounds; stable, homogeneous, preferably concentrated, aqueous liquid and solid textile treatment compositions; and intermediate compositions and/or processes for making said compositions. The compositions of the present invention contain diester quaternary ammonium compounds wherein the fatty acyl groups have 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 being less than about 65% by weight, wherein said compounds are capable of forming concentrated aqueous compositions with concentrations greater than about 13% by weight at an Iodine Value of greater than about 10 without viscosity modifiers other than normal polar organic solvents present in the raw material of the compound or added electrolyte.

Concentrated biodegradable quaternary ammonium fabric softener

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--;
