Abstract

Laundry treatment composition comprising a substituted polysaccharide having a degree of substitution, DS, of from 0.01 to 0.99 and a specific degree of blockiness, DB, such that either DS+DB is of at least 1 or DB+2DS−DS² is of at least 1.20, and a laundry adjunct ingredient.

Claims

1. A composition being a laundry treatment composition or component thereof, comprising:

a substituted polysaccharide selected from the group consisting of galactomannan, glucomannan, a homoxylan, an (arabino)glucuroxylan, a (glucurono)arabinoxylan, and an arabinoxylan, the substituted polysaccharide having a degree of substitution, DS, of from 0.55 to 0.99 and a degree of blockiness, DB, such that either DS+DB is at least 1.00 or DB+2DS−

DS² is at least 1.20 and

a laundry adjunct ingredient.

2. The composition according to claim 1, wherein the substituted polysaccharide has a degree of blockiness, DB, of at least 0.35.

3. The laundry composition according to claim 1, wherein the substituted polysaccharide has a DS+DB, of from 1.05 to 2.00.

4. The composition according to claim 1, wherein the substituted polysaccharide is galactomannan or glucomannan.

5. The composition according to claim 1, wherein the substituted polysaccharide is selected from the group consisting of a homoxylan, an (arabino)glucuroxylan, a (glucurono)arabinoxylan, and an arabinoxylan.

6. The composition according to claim 2, wherein the substituted polysaccharide comprises at least one sugar unit of its backbone which is substituted with a substituent selected from the group consisting of branched, linear or cyclic, substituted or not substituted, saturated or unsaturated alkyl, amine (primary, secondary, tertiary), ammonium salt, amide, urethane, alcohol, carboxylic acid, tosylate, sulfonate, sulfate, nitrate, phosphate, silicone and mixtures thereof.

7. The composition according to claim 1, further comprising an enzyme having endo-β

-1,4-glucanase activity.

8. The composition according to claim 1, comprising at least 1% by weight, based on the weight of the composition, of substituted polysaccharide.

9. The composition according to claim 1, further comprising less than 15% by weight, based on the weight of the composition, of one or more builders selected from the group consisting of phosphate builders, silicate builders, and zeolite builders.

10. The composition according to claim 9, comprising less than 10% by weight, based on the weight of the composition, of the one or more builders.

11. The composition according to claim 9, comprising less than 5% by weight, based on the weight of the composition, of the one or more builders.

12. A composition being a laundry treatment composition or component thereof, comprising:

a substituted polysaccharide selected from the group consisting of galactomannan, glucomannan, a homoxylan, an (arabino)glucuroxylan, a (glucurono)arabinoxylan, an arabinoxylan, and a xyloglucan, the substituted polysaccharide having a degree of substitution, DS, of from 0.55 to 0.99 and a degree of blockiness, DB, of at least 0.35, such that either DS+DB is at least 1.00 or DB+2DS−

DS² is at least 1.20 and

a laundry adjunct ingredient.

13. The laundry composition according to claim 12, wherein the substituted polysaccharide has a DS+DB, of from 1.05 to 2.00.

14. The composition according to claim 12, wherein the substituted polysaccharide is a xyloglucan.

15. The composition according to claim 12, wherein the substituted polysaccharide is galactomannan or glucomannan.

16. The composition according to claim 12, wherein the substituted polysaccharide is selected from the group consisting of a homoxylan, an (arabino)glucuroxylan, a (glucurono)arabinoxylan, and an arabinoxylan.

17. The composition according to claim 12, wherein the substituted polysaccharide comprises at least one sugar unit of its backbone which is substituted with a substituent selected from the group consisting of branched, linear or cyclic, substituted or not substituted, saturated or unsaturated alkyl, amine (primary, secondary, tertiary), ammonium salt, amide, urethane, alcohol, carboxylic acid, tosylate, sulfonate, sulfate, nitrate, phosphate, silicone and mixtures thereof.

18. The composition according to claim 12, further comprising an enzyme having endo-β

-1,4-glucanase activity.

19. The composition according to claim 12, comprising at least 1% by weight, based on the weight of the composition, of substituted polysaccharide.

20. The composition according to claim 12, comprising less than 15% by weight, based on the weight of the composition, of at least one builder selected from the group consisting of phosphate builders, silicate builders, and zeolite builders.
