Abstract
Liquid fabric softener compositions comprising (a) water-insoluble cationic softeners, (b) water-soluble cationic antibacterial agents and (c) cationic rheology modifying polymers are described that are stable homogenous mixtures. A method for determining stability of the softener formulations or determining the amount of component (a), (b) or (c) involves calculating a stability index of the formulation according to the following equation: Stability formula index=[(wt % of the (a) component+3*(wt % of the (c) component)]/[wt % of the (b) component], wherein a desirable stability index value is 2.5 or greater than 2.5.

- c) from 0.05% to 5% by weight cationic acrylics polymer;
- and
- d) water.
An antibacterial fabric softener composition comprising
- from 1% to 40% by weight ditallowethyl ester dimethyl ammonium chloride or di tallowethyl hydroxyethylmonium methosulfate;
- one or more water-soluble cationic antibacterial agents;
- from 0.05 to 5.0% by weight N,N,N-Trimethyl-2-((2-methyl-1-oxo-2-propenyl)oxy)ethanaminium chloride homopolymer;
- and
- water.
A liquid fabric softener composition comprising:
- a) water-insoluble quaternary ester or diester ammonium salt;
- b) water-soluble cationic antibacterial agent of formula (VIII):
- wherein
- R2 and R3 are the same or different C8-C12 alkyl, or
- R2 is C12-16 alkyl, C8-18 alkylethoxy, C8-18 alkylphenoxyethoxy and R3 is benzyl, and
- X is a halide or is methosulfate;
- and
- c) a cationic polymer of formula (IX):
- 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 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 chosen from the group consisting of halides, sulfates, methosulfate, trifluoromethane sulfonate, tetrafluoroborate, carbonates, bicarbonates, and mixtures thereof, and
- n is between several hundred to about 100 million, wherein a sum of the amount of the water-insoluble quaternary ester or diester ammonium salt and 3 times the amount of the cationic polymer of formula (IX) is greater than or equal to 2.5 times the amount of the water-soluble cationic antibacterial agent of formula (VIII).
