Abstract

Compositions comprising cellulase and at least one poly alpha-1,3-glucan ether compound having a degree of substitution with an organic group of about 0.05-3.0 are disclosed. Such compositions can be dry or aqueous, the latter of which can have a viscosity of at least about 10 cPs. The disclosed composition can be in the form of a personal care product, household product, or industrial product, for example. Also disclosed are a method for preparing an aqueous composition comprising cellulase and a poly alpha-1,3-glucan ether compound, and a method of treating a material such as fabric by contacting it with this aqueous composition.

Claims

1. A composition comprising a cellulase and a poly alpha-1,3-glucan compound comprising the structure:

2. The composition of claim 1, wherein the organic group is selected from the group consisting of carboxy alkyl, hydroxy alkyl, and alkyl.

3. The composition of claim 2, wherein the organic group is selected from the group consisting of carboxymethyl, hydroxypropyl, dihydroxypropyl, hydroxyethyl, methyl, and ethyl.

4. The composition of claim 2, wherein the organic group is a carboxymethyl group.

5. The composition of claim 1, wherein the composition is in the form of a personal care product, household product, or industrial product.

6. The composition of claim 5, wherein the composition is a fabric care product.

7. The composition of claim 1, wherein the composition is an aqueous composition.

8. The composition of claim 7, wherein the composition has a viscosity of at least about 10 centipoise.

9. The composition of claim 1, wherein at least 95% of the glycosidic linkages of the poly alpha-1,3-glucan compound are alpha-1,3 glycosidic linkages.

10. The composition of claim 1, wherein the poly alpha-1,3-glucan compound has one or more of the same organic group.

11. The composition of claim 1, wherein the poly alpha-1,3-glucan compound has two or more different organic groups.

12. The composition of claim 1, wherein the composition comprises a surfactant.

13. The composition of claim 1, wherein the composition comprises less than 1 part-per-million of the cellulase.

18. A method of treating a material, said method comprising:

contacting the material with a composition according to claim 7.

19. The method of claim 18, wherein the material comprises fabric.

20. The method of claim 19, wherein the fabric comprises a (i) natural fiber, (ii) synthetic fiber, or a combination of both (i) and (ii).

21. The method of claim 19, wherein the poly alpha-1,3-glucan compound adsorbs to the fabric.

22. The method of claim 18, wherein at least 95% of the glycosidic linkages of the poly alpha-1,3-glucan compound are alpha-1,3 glycosidic linkages.

14. A method for preparing an aqueous composition, the method comprising:

contacting an aqueous composition with a poly alpha-1,3-glucan compound comprising the structure;

15. The method of claim 14, wherein said cellulase is:

(i) comprised in the aqueous composition prior to said contacting step, or

(ii) added to the aqueous composition during or after said contacting step.

16. The method of claim 14, wherein:

(i) the viscosity of the aqueous composition is increased by said poly alpha-1,3-glucan compound, and/or

(ii) the shear thinning behavior or the shear thickening behavior of the aqueous composition is increased by said poly alpha-1,3-glucan compound.

17. The method of claim 14, wherein at least 95% of the glycosidic linkages of the poly alpha-1,3-glucan compound are alpha-1,3 glycosidic linkages.
