Abstract

Treatment compositions, such as fabric care or dish care compositions, that include poly alpha-1,6-glucan ether compounds, which include poly alpha-1,6-glucans substituted with at least one positively charged organic group, the compounds being characterized by, for example, a degree of substitution of about 0.001 to about 3.0, and optionally, where about 3% or more of the backbone glucose monomer units have branches via alpha-1,2- and/or alpha-1,3-glycosidic linkages. Methods related to making and using such compositions.

First claim

What is claimed is:

1. A treatment composition comprising:
a poly alpha-1,6-glucan ether compound comprising a poly alpha-1,6-glucan substituted with at least one positively charged organic group,
wherein the poly alpha-1,6-glucan ether compound is characterized by:
(a) a weight average molecular weight of from about 1000 to about 150,000 daltons,
(b) a backbone of glucose monomer units wherein greater than or equal to 65% of the glucose monomer units are linked via alpha-1,6-glycosidic linkages,
(c) from about 35% to about 45%, of the glucose monomer units have branches via alpha-1,2-glycosidic linkages, and
(d) a degree of cationic substitution of about 0.001 to about 3.0;

the treatment composition further comprising a treatment adjunct ingredient;
wherein the treatment composition is a fabric care composition, a dish care composition, or a mixture thereof.

2. The treatment composition according to claim 1 , wherein the positively charged organic group comprises a substituted ammonium group.

3. The treatment composition according to claim 2 , wherein the quaternary ammonium group comprises at least one C 1 to C 18 alkyl group.

4. The treatment composition according to claim 2 , wherein the quaternary ammonium group comprises a trimethylammonium group.

5. The treatment composition according to claim 1 , wherein the positively charged organic group comprises a quaternary ammonium hydroxyalkyl group.

6. The treatment composition according to claim 5 , wherein the quaternary ammonium hydroxyalkyl group comprises a trimethylammonium hydroxyalkyl group.

7. The treatment composition according to claim 1 , wherein the poly alpha-1,6-glucan ether compound is characterized by a biodegradability, as determined by the Biodegradability Test Method described herein (i.e., the Carbon Dioxide Evolution Test Method of OECD Guideline 301B), of at least 5% on the 90th day of the test duration.

8. The treatment composition according to claim 1 , wherein the treatment composition comprises from about 0.01% to about 10%, by weight of the treatment composition, of the poly alpha-1,6-glucan ether compound.

9. The treatment composition according to claim 1 , wherein the treatment adjunct ingredient is selected from the group consisting of surfactants, conditioning actives, deposition aids, rheology modifiers or structurants, bleach systems, stabilizers, builders, chelating agents, dye transfer inhibiting agents, dispersants, enzymes, enzyme stabilizers, catalytic metal complexes, polymeric dispersing agents, clay and soil removal/anti-redeposition agents, brighteners, suds suppressors, silicones, hueing agents, aesthetic dyes, additional perfumes perfume delivery systems, structure elasticizing agents, carriers, hydrotropes, processing aids, anti-agglomeration agents, coatings, formaldehyde scavengers, pigments, and mixtures thereof.

10. The treatment composition according to claim 1 , wherein the treatment composition is in the form of a liquid composition, a granular composition, a hydrocolloid, a single-compartment pouch, a multi-compartment pouch, a dissolvable sheet, a pastille or bead, a fibrous article, a tablet, a stick, a bar, a flake, a foam/mousse, a non-woven sheet, or a mixture thereof.

11. The treatment composition according to claim 1 , wherein the treatment composition is a liquid characterized by a viscosity of from about from 1 to 1500 centipoises (1-1500 mPa*s) at 20 s −1 and 21° C.

12. The treatment composition according to claim 1 , wherein the treatment composition is a laundry detergent composition, a fabric conditioning composition, a laundry additive, a fabric pre-treat composition, a fabric refresher composition, an automatic dishwashing composition, a manual dishwashing composition, or a mixture thereof.

13. The treatment composition according to claim 1 , wherein at least one of (a)-(d) is true:
(a) the treatment composition is in the form of a single-compartment pouch or a multi-compartment pouch, and wherein the treatment adjunct ingredient comprises less than 20% water by weight of the treatment composition,
(b) the treatment composition is in the form of particles,
wherein individual particles have a mass of from about 1 mg to about 1 gram, and
wherein the particles comprise the poly alpha-1,6-glucan ether compound dispersed in a water-soluble carrier;

(c) the treatment composition is in the form of a liquid,
the treatment composition comprising from about 40% to about 95%, by weight of the treatment composition, of water,
the treatment composition further comprising from about 5% to about 50%, by weight of the treatment composition, of surfactant,

(d) the treatment composition is in the form of a liquid,
the treatment composition comprising from about 40% to about 98%, by weight of the treatment composition, of water, and
from about 1% to about 35%, by weight of the treatment composition, of a fabric softening agent, preferably a quaternary ammonium compound and/or a silicone.
