Abstract

Official abstract text for this publication.

A hydrocolloid or aqueous solution comprising a poly alpha-1,3-glucan ether compound is disclosed having a viscosity of at least about 10 centipoise (cPs). The poly alpha-1,3-glucan ether compound in these compositions has a degree of substitution of about 0.05 to about 3.0. Also disclosed is a method for increasing the viscosity of a hydrocolloid or aqueous composition using a poly alpha-1,3-glucan ether compound.

First claim

Opening claim text (preview).

What is claimed is: 1. A coating comprising a poly alpha-1,3-glucan ether compound represented by the structure: wherein (i) n is at least 6, (ii) each R is independently an H or organic group, and (iii) the compound has a degree of substitution up to about 3.0. 2. The coating of claim 1 , wherein at least one organic group is an alkyl. 3. The coating of claim 2 , wherein the alkyl is a methyl, ethyl, propyl, or butyl. 4. The coating of claim 1 , wherein at least one organic group is a hydroxy alkyl. 5. The coating of claim 4 , wherein the hydroxy alkyl is a hydroxypropyl, dihydroxypropyl, or hydroxyethyl. 6. The coating of claim 1 , wherein at least one organic group is a carboxy alkyl. 7. The coating of claim 6 , wherein the carboxy alkyl is a carboxymethyl. 8. The coating of claim 1 , wherein at least one organic group comprises a chain of one or more carbons in which one or more hydrogens are substituted with another atom or functional group. 9. The coating of claim 1 , wherein the degree of substitution is about 0.05 to about 3.0. 10. The coating of claim 1 , wherein the degree of substitution is about 0.2 to about 2.0. 11. The coating of claim 1 , wherein the degree of substitution is about 0.3. 12. The coating of claim 7 , wherein the degree of substitution is about 0.05 to about 3.0. 13. The coating of claim 7 , wherein the degree of substitution is about 0.2 to about 2.0. 14. The coating of claim 7 , wherein the degree of substitution is about 0.3. 15. The coating of claim 1 , wherein at least 90% of the glycosidic linkages of the poly alpha-1,3-glucan ether compound are alpha-1,3 glycosidic linkages. 16. The coating of claim 1 , wherein the coating is a tablet coating. 17. The coating of claim 1 , wherein the coating is on paper. 18. The coating of claim 1 , wherein the coating is on a non-woven fabric. 19. The coating of claim 1 , wherein the coating is on a fabric.
