View Patent ↗A liquid fabric treatment composition comprising from 50 to 92% by weight of water, from 1 to 15% by weight of one or more alkylated sugars, from 1 to 15% by weight of one or more fatty acids, from 5 to 25% by weight of one or more fatty acid esters, and from 1 to 15% by weight of fatty acid soap.
1. A liquid fabric treatment composition comprising:
(i) from 50 to 92% by weight of water;
(ii) from 1 to 15% by weight of one or more sugars that has been derivatised by esterification or etherification with an alkyl or alkenyl chain;
(iii) from 1 to 15% by weight of one or more fatty acids;
(iv) from 5 to 25% by weight of one or more fatty acid esters; and
(v) from 1 to 15% by weight of fatty acid soap.
2. A composition as claimed in claim 1 in which the fatty acid is present in an amount from 2 to 5% by weight based on the total weight of the composition.
3. A composition according to claim 1 wherein said derivatised sugar is present in an amount of from 3 to 10 wt % based on the total weight of the composition.
4. A composition according to claim 1 in which the fatty acid soap is present in an amount from 3 to 10% by weight based on the total composition.
5. A composition according to claim 1 wherein the fatty acid ester is derived from coconut oil.
6. A method according to claim 5 wherein the fatty acid ester is a fatty acid triglyceride.
7. A composition according to claim 1 wherein said sugar has been derivatised by esterification with an alkyl or alkenyl chain.
8. A composition according to claim 1 wherein said sugar has been derivatised by etherification with an alkyl or alkenyl chain.
9. A composition according to claim 1 wherein the fatty acid ester is derived from palm kernel oil.
10. A composition according to claim 1 which additionally comprises the cationic cellulose ether deposition polymer in an amount of from 0.1 to 5% by weight based on the total weight of the composition.
11. A composition according to claim 1 wherein the amount of water is from 70 to 92% by weight based on the total weight of the composition.
12. A method of preparing a composition as claimed in claim 1 which includes preparing the soap in situ by the steps of reacting together in the presence of water,
an ester-containing soap precursor,
a base material, and
optionally a solvent.
13. A method according to claim 12 wherein the reaction is carried out at a temperature of from 50 to 100° C.
14. A method according to claim 12 wherein the ester-containing soap precursor is a sugar that has been derivatised by esterification with an alkyl or alkenyl chain.
15. A method according to claim 14 wherein said derivatised sugar ester is a sucrose polyester.
16. A method according to claim 12 wherein the ester-containing soap precursor is a fatty acid ester.
17. A method according to claim 12 wherein the base material is an inorganic base.
18. A method according to claim 17 wherein the base material is an alkali metal hydroxide.
19. A method according to claim 12 wherein the base material is an organic base.
20. A method according to claim 12 wherein the reaction is carried out at a temperature of from 60 to 80° C.
