Abstract

The disclosure relates to compositions comprising a polysaccharide derivative, wherein the polysaccharide derivative comprises a polysaccharide substituted with a) at least one hydrophobic group, and b) at least one hydrophilic group, wherein the polysaccharide is poly alpha-1,3-glucan, poly alpha-1,6-glucan, or poly alpha-1,3-1,6-glucan.

First claim

What is claimed is:

1. A product comprising:
from about 1% to about 60% by weight of a surfactant; and from about 0.1% to about 10% by weight of a polysaccharide derivative, wherein the polysaccharide derivative comprises a polysaccharide substituted with a) at least one hydrophilic group comprising a carboxylic acid, a carboxylic acid salt, a sulfonic acid derivative, a sulfonic acid derivative salt, a sulfuric acid derivative, a sulfuric acid derivative salt, a thiosulfate, a thiosulfate salts, a phosphoric acid derivative, a phosphoric acid derivative salt, an alkyl amine, an alkyl substituted ammonium salt, a quaternized pyridine salt, a quaternized imidazole salt, or a combination thereof; and b) at least one hydrophobic group; wherein the polysaccharide is a poly alpha-1,6-glucan or poly alpha-1,3-1,6-glucan; wherein said product is a household product.

2. The product 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, a multi-compartment sachet, a single compartment pouch, or a multi-compartment pouch.

3. The product of claim 1 , further comprising at least one of 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 re-deposition 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.

4. The product of claim 3 , wherein the enzyme is a cellulase, a protease, an amylase, a lipase, or a combination thereof.

5. The product of claim 1 , wherein the polysaccharide derivative at 2 wt % has a surface tension of less than 65 mN/m.

6. A water-soluble unit dose article comprising a water-soluble film and a composition from claim 1 .

7. The water soluble unit does article according to claim 6 comprising at least two compartments.

8. The water soluble unit does article according to claim 6 comprising at least three compartments.

9. The water soluble unit does article according to claim 7 where the compartments are arranged in a superposed orientation or in a side-by-side orientation.

10. A method of treating a substrate, where the method includes the step of contacting the substrate with the household product of claim 1 in the presence of water, wherein the substrate is a fabric or a hard surface.

11. A method of treating a fabric with the product of claim 1 comprising applying the product to the fabric, wherein the treated fabric has a change in WICIE of +1.5 or more units versus the fabric before treatment, as determined according to the L*a*b* WICIE method.

12. A product comprising:
from about 1% to about 60% by weight of a non-petroleum derived surfactant; from about 0.1% to about 10% by weight of a polysaccharide derivative, wherein the polysaccharide derivative comprises a polysaccharide substituted with
c) at least one hydrophobic group; and
d) at least one hydrophilic group;
wherein the polysaccharide is poly alpha-1,6-glucan or poly alpha-1,3-1,6-glucan;
wherein said product is a household product.

13. The product of claim 12 , wherein the product is free of dye and brightener.

14. The product of claim 1 , wherein the at least one hydrophilic group comprises a sulfonic acid derivative, a sulfonic acid derivative salt, a sulfuric acid derivative, a sulfuric acid derivative salt, a thiosulfate, a thiosulfate salts, a phosphoric acid derivative, a phosphoric acid derivative salt, an alkyl amine, an alkyl substituted ammonium salt, a quaternized pyridine salt, a quaternized imidazole salt, or a combination thereof.

15. The product of claim 12 , wherein the at least one hydrophilic group comprises a carboxylic acid, a carboxylic acid salt, a sulfonic acid derivative, a sulfonic acid derivative salt, a sulfuric acid derivative, a sulfuric acid derivative salt, a thiosulfate, a thiosulfate salts, a phosphoric acid derivative, a phosphoric acid derivative salt, an alkyl amine, an alkyl substituted ammonium salt, a quaternized pyridine salt, a quaternized imidazole salt, or a combination thereof.
