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) at least a first and a second fatty acid ester, wherein the source of said first fatty acid ester is different from the source of said second fatty acid ester, and wherein the sources of said first and second fatty acid esters are selected from the group consisting of coconut oil, palm oil, palm kernel oil and sunflower oil;
(ii) a fatty acid soap;
(iii) perfume;
(iv) optionally a fatty acid; and
(v) optionally a cellulose ether cationic deposition polymer,wherein, in at least the first fatty acid ester, 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.

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.
