Fabric softening composition comprising esterquat, cationic acrylic polymer, and germicidal cationic surfactant

A liquid fabric softener composition consisting essentially of:

• a) from 1-10% by weight water-insoluble quaternary ester or diester ammonium salt;
• b) from 1-10% by weight of one or more water-soluble cationic antibacterial agents selected from the group consisting of alkyl dimethyl benzylammonium chloride, octyl decyl dimethylammonium chloride, dioctyl dimethylammonium chloride, and didecyl dimethylammonium chloride;
• c) from 0.05% to 5% by weight cationic acrylics polymer;
• and
• d) water:
• wherein the cationic acrylics polymer is a compound of formula (IX) or mixtures thereof
• wherein
• R4 is H or CH3;
• Y is O or NH;
• Z is a linear alkyl chain of methylene units (CH2)x, where x is an integer from 2 to 18;
• a substituted alkyl chain from 2 to 18 carbons in length having at least one hydroxyl group anywhere along the chain length;
• a benzene ring wherein the Y and the N substituents attach to the intervening benzene ring in a para relationship;
• or a branched alkyl chain having a total number of carbons atoms from 2 to 18 carbon atoms;
• R1, R2, and R3 are, independently, —CH3, —CH2—C6H5, —C2H5, -n-C6H13, -n-C10H21, -naphthalenyl, -benzofuranyl, or —CH2—C6H4—CH2—O—C6H4—CHO;
• X is an anion selected from the group consisting of halides, sulfates, methosulfate, trifluoromethane sulfonate, tetrafluoroborate, carbonates, bicarbonates, and mixtures thereof;
• n is between 200 to about 100 million;
• and
• wherein the mixture is a liquid of homogeneous dispersion with a stability formula index of at least 2.5, defined by the formula (a+3c)/b.
