Abstract

The disclosure relates to compositions comprising a poly alpha-1,3-glucan derivative. The poly alpha-1,3-glucan derivative is a poly alpha-1,3-glucan polymer wherein the polymer is substituted with at least one polyether group and/or polyamine group. Compositions comprising the poly alpha-1,3-glucan derivative are useful as detergent compositions.

Claims (48)

1. A composition comprising a poly alpha-1,3-glucan derivative, wherein the poly alpha-1,3-glucan derivative comprises poly alpha-1,3-glucan substituted with one or more polyamine groups.

2. The composition of claim 1 , wherein the composition further comprises at least one of a surfactant, an enzyme, a detergent builder, a complexing agent, a polymer, a soil release polymer, a surfactancy-boosting polymer, a bleaching agent, a bleach activator, a bleaching catalyst, a fabric conditioner, a clay, a foam booster, a suds suppressor, an anti-corrosion agent, a soil-suspending agent, an anti-soil redeposition agent, a dye, a bactericide, a tarnish inhibitor, an optical brightener, a perfume, a saturated or unsaturated fatty acid, a dye transfer inhibiting agent, a chelating agent, a hueing dye, a calcium cation, a magnesium cation, a visual signaling ingredient, an anti-foam, a structurant, a thickener, an anti-caking agent, a starch, sand, a gelling agent, or a combination thereof.

3. The composition of claim 1 , in the form of a liquid, a gel, a powder, a hydrocolloid, an aqueous solution, a granule, a tablet, a capsule, a single compartment sachet, or a multi-compartment sachet.

4. The composition of claim 1 , wherein the poly alpha-1,3-glucan comprises a backbone of glucose monomer units of which greater than or equal to 50% of the glucose monomer units are linked via alpha-1,3-glycosidic linkages.

5. The composition of claim 4 , wherein greater than or equal to 90% of the glucose monomer units are linked via alpha-1,3-glycosidic linkages.

6. The composition of claim 1 , wherein the one or more polyamine groups have a repeat unit according to ((CH 2 ) y NH), wherein y is 2 to 6 inclusive.

7. The composition of claim 1 , wherein the one or more polyamine groups is a linear polyamine, a branched polyamine, or a dendritic polyamine.

8. The composition of claim 1 , wherein the one or more polyamine groups comprise a radical represented by Structure 3c:

wherein

each R 3 or R 4 is independently hydrogen, C 1 to C 12 alkyl, (—R 7 O—) x H, a polyamine, or (—R 7 —NR 5 ) q R 6 ;

each R 5 or R 6 is independently hydrogen, R 8 , or (—R 7 O—) x H;

each R 7 is independently a C 1 to C 12 alkylene, optionally substituted with hydroxyl;

R 8 is independently hydrogen, a C 1 to C 12 alkyl, or a cation;

each x is independently 2 to 100; and

each q is independently 0 to 12.

9. The composition of claim 1 , wherein the one or more polyamine groups comprise a radical represented by Structure 3g:

wherein

each R 5 or R 6 is independently hydrogen, R 8 , or (—R 7 O—) x H;

each R 7 is independently a C 1 to C 12 alkylene, optionally substituted with hydroxyl;

each R 8 is independently hydrogen, C 1 to C 12 alkyl, or a cation;

each x is independently 2 to 100; and

each q is independently 0 to 12.

10. The composition of claim 2 , wherein the enzyme comprises at least one protease.

11. A method for treating a substrate comprising:

(i) providing a composition, wherein the composition comprises a poly alpha-1,3-glucan derivative; and

(ii) contacting the substrate with the composition;

wherein the poly alpha-1,3-glucan derivative is a poly alpha-1,3-glucan substituted with one or more polyamine groups.

12. The method of claim 11 , wherein the composition further comprises at least one of a surfactant, an enzyme, a detergent builder, a complexing agent, a polymer, a soil release polymer, a surfactancy-boosting polymer, a bleaching agent, a bleach activator, a bleaching catalyst, a fabric conditioner, a clay, a foam booster, a suds suppressor, an anti-corrosion agent, a soil-suspending agent, an anti-soil redeposition agent, a dye, a bactericide, a tarnish inhibitor, an optical brightener, a perfume, a saturated or unsaturated fatty acid, a dye transfer inhibiting agent, a chelating agent, a hueing dye, a calcium cation, a magnesium cation, a visual signaling ingredient, an anti-foam, a structurant, a thickener, an anti-caking agent, a starch, sand, a gelling agent, or a combination thereof.

13. The method of claim 11 , wherein the composition is in the form of a liquid, a gel, a powder, a hydrocolloid, an aqueous solution, a granule, a tablet, a capsule, a single compartment sachet, or a multi-compartment sachet.

14. The method of claim 11 , wherein the poly alpha-1,3-glucan comprises a backbone of glucose monomer units of which greater than or equal to 50% of the glucose monomer units are linked via alpha-1,3-glycosidic linkages.

15. The method of claim 14 , wherein greater than or equal to 90% of the glucose monomer units are linked via alpha-1,3-glycosidic linkages.

16. The method of claim 11 , wherein the one or more polyamines have a repeat unit of ((CH 2 ) y NH), wherein y is 2 to 6 inclusive.

17. The method of claim 11 , further comprising a step of (iii) rinsing the substrate.

18. The method of claim 11 , wherein the one or more polyamine groups comprise a radical represented by Structure 3c:

wherein

each R 3 or R 4 is independently hydrogen, C 1 to C 12 alkyl, (—R 7 O—) x H, a polyamine, or (—R 7 —NR 5 ) q R 6 ;
