Claims

1 A water-soluble package for holding a unit dose composition, the water-soluble package comprising a water-soluble substrate having a thickness from 30 micrometres to 200 micrometres, said substrate comprising:

i. a film-forming material; and,

ii. at least 8wt% surfactant.

wherein the surfactant is an anionic surfactant.

2 A package according to claim 1 or 2 wherein the anionic surfactant is selected from alkoxylated Ce-ie anionic surfactant, sulphate surfactant, sulfonate surfactant or mixtures thereof.

3 A package according to claim 3 wherein the alkoxylated Ce-ie anionic surfactant is a sodium lauryl ether sulphate with 1 to 3 ethylene oxide group.

4 A package according to any one of the preceding claims comprises a further surfactant selected from a non-ionic surfactant, amphoteric surfactant, cationic surfactant, preferably an alkoxylated non-ionic surfactant.

5 A package according to any one of the preceding claims wherein the water- soluble substrate has uniformly dispersed therein gas bubbles having an average diameter less than the total thickness of the substrate.

6 A package as claimed in claim 6 wherein the gas bubbles has a total volume from 80 to 99% of the total volume of the substrate.

7 A package according to any one of the preceding claims wherein the water- soluble substrate has a basis weight in the range from 35 grams per square metre to 50 grams per square metre.

8 A package according to any one of the preceding claims wherein the film-forming material is selected from polyvinyl alcohol, partially hydrolysed polyvinyl acetate, polyvinyl acetate, modified polyvinyl alcohol, carboxy methylcellulose, hydroxypropyl methylcellulose or mixtures thereof.

A package according to any one of the preceding claims wherein the film-forming material is partially hydrolysed having a degree of hydrolysis ranging from 60% to 99%.

A package according to any one of the preceding claims wherein the amount of anionic surfactant is from 8wt% to 25wt%.

A package according to any one of the preceding claims wherein the amount of film- forming material is from 55 to 80% by weight of the water-soluble substrate.

A package according to any one of the preceding claims wherein the water-soluble substrate comprises a plasticizer selected from the group consisting of glycerol, glycerin, diglycerin, hydroxypropyl glycerine, sorbitol, methylene glycol diethylene glycol, triethylene glycol, tetraethylene glycol, propylene glycol, polyethylene glycols, neopentyl glycol, trimethylolpropame, polyether polyols, ethanolamines, and mixtures thereof.

A package according to any one of the preceding claims wherein the water-soluble substrate encloses a composition or material that is a powder, particulate, tablet or granular form.

A package as claimed in claim 13 wherein the composition is a dishwashing composition, fabric treatment composition or a laundry detergent composition.

Use of a water-soluble package according to any one of the preceding claims for washing dishes, treating textiles or laundering textiles.
