Fabric softening compositions containing mixtures of substituted imidazoline fabric softener materials and highly ethoxylated curd dispersant

Liquid fabric softening composition in the form of an aqueous dispersion comprising:

• (a) from about 3% to about 30% of sub-micron size particles of substituted imidazoline fabric softener material which has the formula:
• ##STR5## wherein:
• each A is either (1) --O--C(O)--, or (2) a single covalent bond, wherein each R is a C.sub.1 C.sub.6 alkyl, alkenyl, hydroxy alkyl, or hydrogen, X and X.sup.1 are, independently, C.sub.11 -C.sub.21 hydrocarbyl groups;
• and m and n are, independently, from about 2 to about 4;
• (b) from about 0.2% to about 3% of scum dispersant material, the said scum dispersant material being less than about 10% by weight of said substituted imidazoline fabric softener material which is highly ethoxylated hydrophobic material that minimizes the formation of scum by the interaction of (a) and any anionic detergent surfactant, detergency builder, or mixtures thereof, in water and wherein said scum dispersant material is selected from the group consisting of:
• (1) polyethoxylated fatty alcohols containing from about 12 to about 30 carbons atoms in the alcohol portion;
• (2) polyethoxylated fatty acids containing from about 12 to about 30 carbons atoms in the fatty acid portion;
• (4) polyethoxylated fatty acid amides containing from about 12 to about 30 carbons atoms in the fatty acid portion;
• (5) polyethoxylated quaternary ammonium compounds which contain from about 15 to about 30 carbons atoms in the quaternary ammonium compound with at least about 12 carbon atoms in one alkyl group;
• (6) polyethoxylated amine oxides which contain from about 14 to about 30 carbons atoms in the amine oxide with at least about 12 carbon atoms in one alkyl group;
• and
• (7) mixtures thereof and contains at least about 17 ethoxy groups per molecule on the average and the polyethylene oxide portion of said scum dispersant material is less than about 97% by weight of the total molecular weight;
• and
• (c) from about 97% to about 59% of aqueous liquid carrier.
