Abstract

A water-soluble pouch including a water-soluble film and at least one compartment enclosed by the film, where the compartment includes a composition, and where the composition includes a siloxane-based polymer suds suppressor.

Claims

1. A multi-compartment water-soluble pouch comprising a water-soluble film and at least two compartments enclosed by the film, and at least one of the compartments comprises a composition, wherein the composition comprises:

a. an anionic surfactant;

b. a non-ionic surfactant;

c. a fatty acid, wherein the fatty acid is selected from the group consisting of lauric acid, tridecylic acid, myristic acid, pentadecylic acid, palmitic acid, margaric acid, stearic acid, arachidic acid, phytanic acid, behenic acid, palmitoleic acid, oleic acid, elaidic acid, vaccenic acid, linoleic acid, cis-elesotearic acid, trans-elosteric acid, arachidonic acid and combinations thereof;

d. a siloxane-based polymer suds suppressor; and

e. from about 0.01% to about 6% by weight of the composition of water;

wherein the anionic surfactant is present at a concentration of between about 35% and about 40% by weight of the composition, the non-ionic surfactant is present at a concentration of about 4% or less by weight of the composition, the suds suppressor is present at a concentration of between about 0.02% and about 1% by weight of the composition, and the fatty acid is present at a concentration of about 4% or less by weight of the composition.

2. The pouch according to claim 1, wherein the non-ionic surfactant is present at a concentration of between about 0.01% and about 4% by weight of the composition.

3. The pouch according to claim 1, wherein the fatty acid is present at a concentration of between about 0.01% and about 4% by weight of the composition.

4. The pouch according to claim 1, wherein the suds suppressor is an organomodified siloxane polymer.

5. The pouch according to claim 1, wherein the anionic surfactant is selected from linear alkyl benzene sulfonate, alkyl ethoxylate sulphate and combinations thereof.

6. The pouch according to claim 1, wherein the composition comprises a structurant.

7. The pouch according to claim 1, wherein the composition comprises at least one adjunct ingredient selected from bleach, bleach catalyst, dye, hueing agents, cleaning polymers, alkoxylated polyamines, polyethyleneimines, alkoxylated polyethyleneimines, soil release polymers, amphiphilic graft polymers, surfactants, solvents, dye transfer inhibitors, chelants, enzymes, perfumes, encapsulated perfumes, perfume delivery agents, suds suppressor, brighteners, polycarboxylates, structurants, anti-oxidants, deposition aids and mixtures thereof.

8. The pouch according to claim 1, wherein the non-ionic surfactant is selected from the group consisting of C8-C18 alkyl ethoxylates;

C6-C12 alkyl phenol alkoxylates wherein optionally the alkoxylate units are ethyleneoxy units, propyleneoxy units or a mixture thereof;

C12-C18 alcohol and C6-C12 alkyl phenol condensates with ethylene oxide/propylene oxide block polymers;

C14-C22 mid-chain branched alcohols, C14-C22 mid-chain branched alkyl alkoxylates having an average degree of alkoxylation of from 1 to 30;

alkylpolysaccharides;

polyhydroxy fatty acid amides;

ether capped poly(oxyalkylated) alcohol surfactants; and

mixtures thereof.
