Abstract

Compositions comprising cellulase and at least one poly alpha-1,3-glucan ether compound having a degree of substitution with a positively charged 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 represented by the structure:

2. The composition of claim 1, wherein the compound is substituted by the positively charged organic group, and the positively charged organic group comprises a substituted ammonium group.

3. The composition of claim 2, wherein the positively charged organic group comprises a trimethylammonium group.

4. The composition of claim 2, wherein the positively charged organic group is a quaternary ammonium group.

5. The composition of claim 1, wherein the compound is substituted by the positively charged organic group, and the positively charged organic group comprises a hydroxy alkyl group or alkyl group.

6. The composition of claim 1, wherein the compound is substituted by the positively charged organic group, and the positively charged organic group comprises a hydroxy alkyl group and a trimethylammonium group.

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

8. The composition of claim 7, wherein the composition is a fabric care product.

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

10. The composition of claim 9, wherein the composition has a viscosity of at least about 10 cPs.

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

contacting the material with a composition according to claim 9.

15. The method of claim 14, wherein the material comprises fabric.

16. The method of claim 15, wherein the poly alpha-1,3-glucan compound adsorbs to the fabric.

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

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

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

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

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

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

12. The method of claim 11, 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.

13. The method of claim 12, wherein:

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.
