Abstract

The present invention relates to treatment compositions containing polymer systems that provide stability and benefit agent deposition as well as methods of making and using same. Such treatment compositions may be used for example as through the wash and/or through the rinse fabric enhancers as well as unit dose treatment compositions.

Claims (32)

1. A composition comprising, based upon total composition weight:

a) from about 0.01% to about 5% of a polymeric mixture that comprises a first polymer and a second polymer in a weight ratio of from about 1:1 to about 2:1;

said first polymer being derived from the polymerization of from about 5 to 100 mole percent of a cationic vinyl addition monomer, from about 0 to 95 mole percent of a non-ionic vinyl addition monomer, from about 0 to about 50 mole percent of an anionic monomer, from about 50 ppm to 1,950 ppm of a cross-linking agent comprising two or more ethylenic functions, 0 ppm to about 10,000 ppm chain transfer agent,

wherein the cationic monomers are selected from the group consisting of methyl chloride quaternized dimethyl aminoethylammonium acrylate, methyl chloride quaternized dimethyl aminoethylammonium methacrylate and mixtures thereof, and

the non-ionic monomers are selected from the group consisting of acrylamide, dimethyl acrylamide and mixtures thereof, wherein the first polymer has the viscosity slope of greater than 3.7;

said second polymer being derived from saccharides; and

b) from about 1% to about 35% of a fabric softener active;

said composition being a fabric and home care product.

2. A composition according to claim 1 , comprising from about 1% to about 35% of a fabric softener active selected from the group consisting of a quaternary ammonium compound, a silicone polymer, a polysaccharide, a clay, an amine, a fatty ester, a dispersible polyolefin, a polymer latex and mixtures thereof.

3. A composition according to claim 2 , wherein;

a) said quaternary ammonium compound comprises an alkyl quaternary ammonium compound and mixtures thereof;

b) said silicone polymer is selected from the group consisting of cyclic silicones, polydimethylsiloxanes, aminosilicones, cationic silicones, silicone polyethers, silicone resins, silicone urethanes, and mixtures thereof;

c) said clay comprises a smectite clay;

d) said dispersible polyolefin is selected from the group consisting of polyethylene, polypropylene and mixtures thereof; and

e) said fatty ester is selected from the group consisting of a polyglycerol ester, a sucrose ester, a glycerol ester and mixtures thereof.

4. A composition according to claim 3 , wherein said fabric softener active comprises a material selected from the group consisting of monoesterquats, diesterquats, triesterquats, and mixtures thereof.

5. A composition according to claim 2 wherein the fabric softening active has an Iodine Value of between 0-140, or when said fabric softening active comprises a partially hydrogenated fatty acid quaternary ammonium compound said fabric softening active has an Iodine Value of 25-60.

6. A composition according to claim 2 , said composition comprising a quaternary ammonium compound and a silicone polymer.

7. A composition according to claim 2 , said composition comprises, in addition to said fabric softener active, from about 0.001% to about 5% of a stabilizer that comprises an alkyl quaternary ammonium compound.

8. A composition according to claim 1 , said composition having a Brookfield viscosity of from about 20 cps to about 1,000 cps.

9. A composition according to claim 1 , said composition comprising an adjunct material selected from the group consisting of surfactants, builders, chelating agents, dye transfer inhibiting agents, dispersants, enzymes, and enzyme stabilizers, catalytic materials, bleach activators, hydrogen peroxide, sources of hydrogen peroxide, preformed peracids, polymeric dispersing agents, clay soil removal/anti-redeposition agents, brighteners, suds suppressors, dyes, hueing dyes, perfumes, perfume delivery systems, structure elasticizing agents, carriers, structurants, hydrotropes, processing aids, solvents and/or pigments and mixtures thereof.

10. A composition according to claim 9 , said composition comprising perfume and/or a perfume delivery system.

11. A composition according to claim 1 , said composition comprising one or more types of perfume microcapsules.

12. A composition according to claim 1 , said composition having a pH from about 2 to about 4.

13. The composition of claim 1 wherein:

said first polymer is derived from the polymerization of from about 10 to 95 mole percent of a cationic vinyl addition monomer, from about 5 to 90 mole percent of a non-ionic vinyl addition monomer, from about 60 ppm to 1,900 ppm of a cross-linking agent comprising two or more ethylenic functions, with the proviso that said first polymer does not comprise an acrylamide unit; and

said second polymer is derived from starch, cellulose, and guar.

14. A composition according to claim 1 , wherein said second polymer is derived from cationically modified saccharides and has a cationic charge density ranging from about 0.2 meq/gm to about 5 meq/gm, at the pH of intended use of the fabric softening composition.

15. A composition according to claim 1 , wherein said second polymer is characterized by a Number Average Molecular Weight (Mn) from about 10,000 Daltons to about 500,000 Daltons.

16. A composition according to claim 1 , wherein said anionic monomer is selected from the group consisting of acrylic acid, methacrylic acid, itaconic acid, crotonic acid, maleic acid, fumaric acid, monomers performing a sulfonic acid or phosphonic acid functions, and their salts.

17. A composition according to claim 16 , wherein said anionic monomer is acrylic acid.
