Abstract

Abstract A textile conditioning composition, especially a liquid composition, intended for use in the final rinse after a washing operation comprises a cationic surfactant, a substantially water insoluble nonionic textile softening agent and a small amount of a polymeric cationic salt, the weight ratio of cationic components to nonionic softener being less than 10:1. Preferred cationic surfactants are the substantially water-insoluble quaternary ammonium fabric softeners and preferred nonionic softening agents are the fatty acid esters of glycerol or sorbitan. Especially useful polymeric materials include the cationic galactomannan gums, especially guar gum.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 190 words
A textile conditioning composition comprising: (a) from about 0.3% to about 4% of a cationic surfactant selected from the group consisting of: (1) non-cyclic quaternary ammonium salts having at least one C 12-30 alkyl chain in the molecule, (2) C 8-25 alkyl imidazolinium salts, and (3) mixture thereof; (b) from about 2% to about 10% of a substantially water-insoluble nonionic textile conditioning agent selected from the group consisting of: (1) C 10-26 fatty acid esters of mono- or polyhydroxy alcohols containing 1 to 12 carbon atoms, (2) esters of fatty alcohols having from 12 to 24 carbon atoms in the alkyl chain and mono- or polycarboxylic acids having from 1 to 8 carbon atoms in the alkyl chain, whereby the total number of carbon atoms in the ester is equal to or greater than 16, and (3) mixtures thereof; and (c) from about 0.05% to about 0.5% of a polymeric cationic salt comprising guar gum which has been rendered cationic by attaching a cationic group to it at one or more of its reactive hydroxyl or carboxyl sites; wherein the weight ratio of (a)+(c) to (b) is less than 10:1.
Claim 2
Dependent Claim 190 words
A textile conditioning composition comprising: (a) from about 0.3% to about 4% of a cationic surfactant selected from the group consisting of: (1) non-cyclic quaternary ammonium salts having at least one C 12-30 alkyl chain in the molecule, (2) C 8-25 alkyl imidazolinium salts, and (3) mixture thereof; (b) from about 2% to about 10% of a substantially water-insoluble nonionic textile conditioning agent selected from the group consisting of: (1) C 10-26 fatty acid esters of mono- or polyhydroxy alcohols containing 1 to 12 carbon atoms, (2) esters of fatty alcohols having from 12 to 24 carbon atoms in the alkyl chain and mono- or polycarboxylic acids having from 1 to 8 carbon atoms in the alkyl chain, whereby the total number of carbon atoms in the ester is equal to or greater than 16, and (3) mixtures thereof; and (c) from about 0.05% to about 0.5% of a polymeric cationic salt comprising guar gum which has been rendered cationic by attaching a cationic group to it at one or more of its reactive hydroxyl or carboxyl sites; wherein the weight ratio of (a)+(c) to (b) is less than 10:1.
Claim 3
Dependent Claim 19 words
The composition of claim 2 wherein the polymeric cationic salt has more than 10 monomeric units in the molecule.
Claim 4
Dependent Claim 23 words
The composition of claim 2 wherein the polymeric cationic salt is a guar gum, quaternised to a D.S. of from 0.1 to 0.5.
Claim 5
Dependent Claim 32 words
A textile conditioning composition as recited in claim 1 which is in the form of an aqueous dispersion and wherein the weight ratio of (a)+(c) to (b) is from 3:1 to 1:1.
Claim 6
Dependent Claim 24 words
The composition of claim 4 wherein the cationic surfactant is selected from a ditallow dimethyl ammonium salt, a 2-tallow-1-methyl-1-(tallow amidoethyl)imidazoline salt and mixtures thereof.
Claim 7
Dependent Claim 34 words
The composition of claim 4 wherein the nonionic textile conditioning agent is selected from the group consisting of glycerol monostearate, glycerol distearate, glycerol mono oleate, glycerol dioleate, sorbitan monostearate, sorbitan distearate and mixtures thereof.
Claim 8
Dependent Claim 22 words
The composition of claim 4 wherein the polymeric cationic salt is a guar gum quaternized to a D.S. from 0.1 to 0.5.
