Abstract

The invention provides a fabric softening composition comprising: i) at least one nonionic fabric saftening agent, and ii) at least one anionic surfactant, and iii) at least one cationic polymer wherein the particles formed from i), ii) and iii) have a net negative charge and the composition comprises no more than 1% by weight of non-polymeric cationic surfactant and/or cationic fabric softening compounds.

Claims (16)

1. A fabric softening composition comprising:
(i) at least one nonionic fabric softening agent, and (ii) at least one anionic surfactant, and (iii)at least one cationic polymer wherein the particles formed from i), ii) and iii) have a net negative charge and the composition comprises no more than 1% by weight non-polymeric cationic surfactant and/or cationic fabric softening compounds.
2) A composition according to claim 1 wherein the nonionic fabric softener (i) comprises a liquid or soft solid derivative of a cyclic polyol (CPE) or of a reduced saccharide (RSE) resulting from 35 to 100% of the hydroxyl groups in the polyol or saccharide being esterified or etherified, the CPE or RSE having 2 or more ester or ether groups independently attached to a C8-C22 alkyl or alkenyl chain.
3) A composition according to claim 2 wherein the CPE or RSE contains at least 35% tri or higher esters.
4) A composition according to any one of the preceeding claims wherein the cyclic polyol or reduced saccharide has 40-80%, preferably 45 - 75%, of the hydroxyl groups esterified and/or etherified.
5) A composition according to any one of the preceeding claims wherein the CPE or RSE has 3 or more ester or ether groups, preferably 4 or more.
6) A composition according to any one of the preceeding claims wherein the CPE or RSE is derived from a monosaccharide or disaccharide.
7) A composition according to any one of the preceding claims comprising 0.5% - 50% by weight of the fabric softening agent, preferably 1% - 30%.
8) A composition according to any one of the preceding claims comprising 0.1% - 10% by weight of the anionic surfactant, preferably 0.2% - 5%.
9) A composition according to any one of the preceding claims wherein the cationic polymer is selected from cationic guar derivatives, cationic cellulose derivatives, cationic starch derivatives and, cationic chitosan derivatives or mixtures thereof.
10) A composition according to any one of the preceding claims comprising 0.01% - 5% by weight of the cationic polymer, preferably 0.1-3%.
11) A composition according to any one of the preceding claims wherein the weight ratio of softening agent to the total amount of anionic surfactant and cationic polymer is within the range 15:1 to 1:10, preferably 10:1 to 1:1.
12) A composition according to any preceding claim which is a liquid, preferably an emulsion.
13) A method of depositing a nonionic fabric softening agent onto fabric from a fabric softening composition, comprising emulsifying the softening agent with an anionic surfactant and a cationic polymer to form a particle having an overall net negative charge in the composition and treating said fabric with said composition.
14) A method of depositing a nonionic fabric softening agent onto fabric from a fabric softening composition, comprising emulsifying the softening agent with an anionic surfactant and then post-dosing an aqueous solution of a cationic polymer to form a particle having an overall negative charge on the composition and treating said fabric with said composition.
15) A method according to claim 13 or claim 14 wherein the fabric softening agent is as defined in any one of the preceeding claims.
16) A method according to either claim 14 or claim 15 wherein the cationic polymer is as defined in claim 9.
