Abstract

A laundry care or dish care composition can include a poly alpha-1,6-glucan derivative, wherein the poly alpha-1,6-glucan derivative includes: (i) a poly alpha-1,6-glucan backbone of glucose monomer units; and (ii) at least one hydrophobic organic group linked to the poly alpha-1,6-glucan backbone through an ether (—O—) linkage moiety; wherein, the poly alpha-1,6-glucan backbone has a weight average degree of polymerization of at least 5; wherein, the poly alpha-1,6-glucan derivative has a degree of substitution of ether linkage moiety of from 0.20 to 1.00; wherein the poly alpha-1,6-glucan derivative is substantially free from hydrophilic substitution.

Claims (15)

1 . A laundry care or dish care composition comprising a poly alpha-1,6-glucan derivative, wherein the poly alpha-1,6-glucan derivative comprises:

(i) a poly alpha-1,6-glucan backbone of glucose monomer units; and

(ii) at least one hydrophobic organic group linked to the poly alpha-1,6-glucan backbone through an ether (—O—) linkage moiety;

wherein, the poly alpha-1,6-glucan backbone has a weight average degree of polymerization of at least about 5;

wherein, the poly alpha-1,6-glucan derivative has a degree of substitution of ether linkage moiety of from about 0.20 to about 1.00;

wherein the poly alpha-1,6-glucan derivative further comprises one or more additional hydrophobic organic groups linked to the poly alpha-1,6-glucan backbone through linkage moiety selected from one or more of ester (—OCO—), carbamate

sulfonate ester (-OSO 2 -), and carbonate ester (—OCOO—);

wherein the poly alpha-1,6-glucan derivative is free from hydrophilic substitution; and

wherein the hydrophobic organic group is a benzyl group substituted with a methyl group; a methyl ether group; or any combination thereof.

2 . The composition according to claim 1 , wherein no hydrophilic organic groups are linked to the poly alpha-1,6-glucan backbone through the ether (—O—) linkage moiety.

3 . The composition according to claim 1 , wherein the alpha-1,6-glucan backbone of the poly alpha-1,6-glucan derivative has a weight average degree of polymerization of either about 5 to about 95, or about 125 to about 4000.

4 . The composition according to claim 1 , wherein, the poly alpha-1,6-glucan derivative has a degree of substitution of ether linkage moiety of about 0.40 to about 0.90.

5 . The composition according to claim 1 , 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, a pad, a multi-compartment sachet, a single compartment pouch, or a multi-compartment pouch.

6 . The composition according to claim 1 , wherein the composition further comprising an ingredient selected from: 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 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 any combination thereof.

7 . The composition according to claim 1 , wherein the composition comprises an enzyme selected from: a cellulase, a protease, an amylase, a lipase, or any combination thereof.
