Abstract

Fabric care compositions comprise cationic starch and fabric softening active, wherein the composition comprises a viscosity of less than about 2000 centipoise.

Claims (16)

1. A fabric softening composition comprising: a fabric softening active; and a cationic starch; wherein the cationic starch comprises a weight average molecular weight range of from about 2,000,000 to about 10,000,000 Daltons; wherein the cationic starch is chemically modified to provide the starch with a net positive charge; and wherein the composition comprises a viscosity of less than about 2000 centipoise;

wherein the cationic starch comprises from about 2% to about 7% of the fabric softening composition; and

wherein the fabric softening active comprises an ester guaternary ammonium comprising compound.

2. The composition of claim 1 , wherein said composition comprises a viscosity less than about 500 centipoise; and wherein the fabric softening compound comprises a quaternary ammonium compound.

3. The composition of claim 2 , wherein said viscosity comprises less than about 200 centipoise; wherein the cationic starch comprises from about 1% to about 7% by weight of the composition.

4. The composition of claim 1 , wherein said composition comprises at least about 2%, by weight of said composition, of said fabric softening active; and wherein the cationic starch comprises from about 2% to about 7% by weight of the composition.

5. The fabric care composition of claim 1 , wherein said composition comprises from 2% to about 7%, by weight of said composition, of said cationic starch.

6. The fabric care composition of claim 5 , wherein said composition comprises at least about 10% by weight of the ester quaternary ammonium comprising compound.

7. The fabric care composition of claim 1 , wherein said cationic starch has an amylose content of from about 0% to about 70%, by weight of said cationic starch.

8. The fabric care composition of claim 7 , wherein said cationic starch has an amylose content of from about 15% to about 50%, by weight of said cationic starch.

9. The fabric care composition of claim 8 , wherein said cationic starch has an amylose content of from about 25% to about 30%, by weight of said cationic starch.

10. The fabric care composition of claim 1 , wherein said cationic starch comprises the weight average molecular weight of from about 50,000 to about 7,000,000 Daltons.

11. The fabric care composition of claim 10 , wherein said cationic starch the weight average molecular weight of from about 150,000 to about 7,000,000 Daltons.

12. The fabric care composition of claim 1 , wherein said cationic starch is cationic maize starch.

13. The fabric care composition of claim 1 , wherein said cationic starch is partially gelatinized cationic starch.

14. A method of softening a fabric comprising the step of contacting said fabric with a composition according to claim 1 .
