Abstract

A unit dose fabric treatment system comprises a water soluble container in which a liquid fabric treatment composition is disposed, the composition comprising one or more fatty acid esters wherein, in at least one of the fatty acid esters, the average proportion of C18 chains is less than 60%, preferably less than 50%, more preferably less than 40%, e.g. less than 30% by weight of the total weight of fatty acid chains in the fatty acid ester.

Claims

1. A fabric treatment system in the form of a unit dose comprising:

(a) a water soluble container which is formed from a water soluble polymer selected from the group consisting of polyvinyl alcohols, polyvinyl alcohol copolymers, partially hydrolyzed polyvinyl acetate, polyvinyl pyrrolidone, alkyl celluloses, ethers and esters of alkyl cellulosics, hydroxy alkyl, carboxy methyl cellulose sodium, dextrin, maltodextrin, water soluble polyacrylates, water soluble polyacrylamides and acrylic acid/maleic anhydride copolymers;

and

(b) a liquid fabric softener composition disposed in said water soluble container, wherein said fabric softener composition comprises;

(i) one or more fatty acid esters;

(ii) a fatty acid soap,

(iii) perfume

(iv) optionally fatty acid; and

(v) optionally a cellulose ether cationic deposition polymer,

(c) wherein, in at least one of the fatty acid esters, the average proportion of C18 chains is less than 60% by weight of the total weight of fatty acid chains in the fatty acid ester.

2. A fabric treatment system according to claim 1 in which in at least one of the fatty acid esters the average proportion of C18 chains is less than 40%.

3. A fabric treatment system according to claim 1 wherein fatty acid is present in an amount from 0.1 to 15% by weight based on the total weight of the composition.

4. A fabric treatment system according to claim 1 wherein the fatty acid ester (i) is coconut oil.

5. A fabric treatment composition according to claim 1 wherein the fatty acid ester (i) is palm kernel oil.

6. A fabric treatment system as claimed in claim 1 wherein the fatty acid soap comprises an alkali metal soap or ammonium or substituted ammonium salt of a fatty acid containing from 8 to 24 carbon atoms and is present in an amount of from 1 to 50% by weight of the composition.

7. A fabric treatment system according to claim 1 wherein the cationic polymer (v) is present in an amount of from 0.1 to 5% by weight based on the total weight of the composition.

8. A fabric treatment system according to claim 1 wherein the level of water is less than 10% by weight, based on the total weight of the composition.

9. A fabric treatment system according to claim 1 wherein the perfume (iv) is present in an amount from 0.5 to 10% by weight, based on the total weight of the composition.

10. A method of treating a fabric which comprises introducing a fabric treatment system as claimed in any preceding claim into a home or automatic laundering machine so that it is present during the wash cycle.
