Abstract

Laundry product compositions containing a stable mixture of at least one water insoluble fabric care benefit agent and at least one delivery enhancing agent that is preferably a dispersible polyolefin, polymer latex, or mixture thereof. Detergent laundry product compositions containing from about 1% to about 80%, by weight of the composition, of a detersive surfactant that is an anionic surfactant, cationic surfactant, nonionic surfactant, amphoteric surfactant, zwitterionic surfactant, or a mixture thereof; from about 0.1% to about 10%, by weight of the composition, of a water insoluble fabric care benefit agent; from about 0.01% to about 5%, by weight of the composition, of a delivery enhancing agent; and wherein the ratio of the delivery enhancing agent to the fabric care benefit agent is from about 1:50 to about 1:1.

Claims

1. A laundry product composition comprising a stable mixture of:

a) from about 0.1% to about 10%, by weight of the composition of at least one water insoluble fabric care benefit agent wherein the water insoluble fabric care benefit agent is a dispersible polyolefin, polymer latex, or a mixture thereof and has a particle size of from about 1 nm to 100 um;

b) from about 0.0 1% to about 5% by weight of the composition, of at least one cationic cellulose delivery enhancing agent;

c) from about 1% to about 80% by weight of the composition, of a surfactant;

d) from about 3.96% to about 80% by weight of the composition, of a builder; and

;

e) a compatible enzyme;

wherein the ratio of the cationic cellulose delivery enhancing agent to the water insoluble fabric care benefit agent is from about 1;

50 to about 1;

1.

2. A laundry product composition according to claim 1 wherein the stable mixture is formed in situ.

3. A laundry product composition according to claim 1 wherein the cationic cellulose has the structure:

9. A laundry product composition according to claim 1 wherein the product is a fabric enhancer.

10. A laundry product composition according to claim 1 wherein the product is a dryer added product.

11. A laundry product composition according to claim 1 wherein the composition, further comprises from about 0.001% to about 10% of an effective enzyme stabilizing system.

12. A laundry product composition according to claim 1 wherein the enzyme stabilizing system comprises calcium ions, boric acid, propylene glycol, short chain carboxylic acids, boronic acids, or mixtures thereof.

15. A method of improving the fabric delivery efficacy of water insoluble fabric care benefit agents utilizing the detergent composition of claim 1.

4. A detergent laundry product composition comprising:

a) from about 1% to about 80%, by weight of the composition, of a detersive surfactant that is an anionic surfactant, cationic surfactant, nonionic surfactant, amphoteric surfactant, zwitterionic surfactant, or a mixture thereof;

b) from about 0.1% to about 10%, by weight of the composition, of a water insoluble fabric care benefit agent wherein said water insoluble fabric care benefit agent is a dispersible polyolefin, polymer latex, or a mixture thereof;

c) from about 0.01% to about 5%, by weight of the composition, of a cationic cellulose delivery enhancing agent;

d) from about 3.96% to about 80%. by weight of the composition, of a builder; and

; and

e) a compatible enzyme;

wherein the ratio of the delivery enhancing agent to the fabric care benefit agent is from about 1;

50 to about 1;

1.

5. A detergent composition according to claim 4 wherein the cationic cellulose has the structure:

6. A detergent composition according to claim 4 wherein the fabric care benefit agent is a dispersible polyolefin that is a polyethylene, a polypropylene, or a mixture thereof.

7. A detergent composition according to claim 4 wherein the fabric care benefit agent is a polymer latex that is a pure butylacrylate, mixture of butylacrylate and a second monomer wherein the second monomer comprises less than 20%, by weight monomer ratio, or mixtures thereof.

8. A detergent composition according to claim 4 wherein the composition is a liquid detergent.

13. A detergent composition according to claim 4 wherein the composition further comprises from about 0.001% to about 10% of an effective enzyme stabilizing system.

14. A detergent composition according to claim 13 wherein the enzyme stabilizing system comprises calcium ions, boric acid, propylene glycol, short chain carboxylic acids, boronic acids, or mixtures thereof.

16. A method of improving the fabric delivery efficacy of water insoluble fabric care benefit agents utilizing the detergent composition of claim 4.
