Abstract

The present invention relates to a novel stable colloidal polysaccharide suspension containing α(1→3)-glucan, a cost-effective method for its preparation, and possible uses of these polysaccharide suspensions.

Claims (12)

1. A product comprising (i) a nonwoven and (ii) a binder of the nonwoven, wherein the binder comprises a polysaccharide comprising α(1→3)-glucan, wherein the α(1→3)-glucan content of the polysaccharide is between 80% and 100% by weight.

2. The product of claim 1 , wherein at least 90% of the α(1→3)-glucan consists of hexose units and at least 50% of the hexose units are linked via α(1→3)-glycosidic bonds.

3. The product of claim 1 , wherein all of the glycosidic bonds of the α(1→3)-glucan are α(1→3)-glycosidic bonds.

4. The product of claim 1 , wherein the weight-average degree of polymerization of the α(1→3)-glucan is between 200 and 2000.

5. The product of claim 1 , wherein the nonwoven is strengthened by the binder.

6. The product of claim 1 , wherein the nonwoven is a wipe.

7. The product of claim 6 , wherein the wipe is a flushable wipe.

8. The product of claim 1 , wherein the binder is penetrated within the nonwoven.

9. The product of claim 1 , wherein the binder is coated on the nonwoven.

10. The product of claim 1 , produced by applying a phase-stable, colloidal suspension of the polysaccharide to the nonwoven.

11. The product of claim 10 , wherein said suspension penetrates into the nonwoven by said applying.

12. The product of claim 10 , wherein said suspension makes a coating on the nonwoven by said applying.
