Unit dose detergent compositions
View Patent ↗The present invention relates to unit dose detergent compositions comprising a water-soluble container formed from a water-soluble film material enclosing a liquid composition with a relatively high water content. In one embodiment, the unit dose detergent composition comprises a water-soluble container formed from a water-soluble film material enclosing a liquid composition, wherein the liquid composition comprises (a) at least one surfactant, (b) at least one humectant selected from the group consisting of polyols having 3 to 9 carbon atoms, and (c) about 15 wt % to about 35 wt % of water.
1. A unit dose detergent composition, comprising: a water-soluble container formed from a water-soluble film material enclosing a liquid composition, wherein the liquid composition comprises:
at least one alkyl ether sulfate (AES),
at least one humectant selected from the group consisting of heptylene glycol, octylene glycol, and mixtures therefor, and
about 15 wt % to about 35 wt % of water, and
wherein the liquid composition comprises about 10 wt % to about 40 wt % of the one or more humectants.
2. The unit dose detergent composition according to claim 1 , wherein the liquid composition comprises about 5 wt % to about 25 wt % of the at least one alkyl ether sulfate (AES).
3. The unit dose detergent composition according to claim 1 , wherein the at least one alkyl ether sulfate (AES) is sodium lauryl ether sulfate (SLES).
4. The unit dose detergent composition according to claim 1 , wherein the water-soluble film material is selected from the group consisting of polyvinyl alcohol (PVA), film forming cellulosic polymer, poly acrylic acid, polyacrylamide, polyanhydride, polysaccharide, and a mixture thereof.
5. The unit dose detergent composition according to any of claim 1 , wherein the water-soluble film material is polyvinyl alcohol (PVA).
6. The unit dose detergent composition according to claim 1 , wherein the liquid composition comprises about 25 wt % to about 35 wt % of water.
7. The unit dose detergent composition according to claim 1 , wherein the liquid composition comprises about 25 wt % of water.
8. The unit dose detergent composition according to claim 1 , wherein the liquid composition comprises about 30 wt % of water.
9. A unit dose detergent composition, comprising: a water-soluble container formed from a water-soluble film material enclosing a liquid composition, wherein the liquid composition comprises:
about 15 wt % to about 30 wt % of at least one anionic surfactant and about 15 wt % to about 30 wt % of at least one nonionic surfactant,
at least one humectant selected from the group consisting of butylene glycol, pentylene glycol, hexylene glycol, heptylene glycol, octylene glycol, 2-methyl-1,3-propanediol, xylitol, sorbitol, mannitol, erythritol, dulcitol, inositol, adonitol, and mixtures thereof, and
about 25 wt % to about 35 wt % of water, and
wherein the liquid composition comprises about 10 wt % to about 40 wt % of the one or more humectants, and
wherein the at least one humectant comprises heptylene glycol, octylene glycol, or a combination thereof.
10. The unit dose detergent composition according to claim 1 , wherein the liquid composition comprises about 30 wt % to about 35 wt % of water.
