Abstract

The instant disclosure relates to methods of making compositions comprising glycerol esters and a fabric softening active. Methods of using such compositions are also disclosed.

Claims

1. A method of making a fabric care composition comprising the steps of:

a) combining a molten mixture of glycerol esters, wherein each glycerol ester in the mixture of glycerol esters has the structure of Formula I

2. The method of claim 1 wherein the first mixture further comprises a dispersant.

3. The method of claim 1 wherein said delivery enhancing agent is a cationic polymer with a net cationic charge density of from about 0.05 meq/g to about 23 meq/g.

4. The method of claim 1 wherein said delivery enhancing agent is a cationic polymer having a weight-average molecular weight of from about 1500 to about 10,000,000.

5. The method of claim 1 wherein said delivery enhancing agent is selected from cationic acrylic based homopolymers, poly(acrylamide-N-dimethyl aminoethyl acrylate) and its quaternized derivatives, poly(acrylamide-N-dimethyl aminoethyl methacrylate) and its quaternized derivatives, polyethyleneimine, or mixtures thereof.

6. A fabric care composition made according to the method of claim 1 wherein the composition comprises from about 3 to about 25% of said fabric softening active by weight of the final composition.

7. A fabric care composition made according to the method of claim 1 wherein the composition comprises from about 3 to about 30% of said mixture of glycerol esters by weight of the final composition.

8. A fabric care composition made according to the method of claim 1 wherein the ratio of the mixture of glycerol esters to the fabric softening active is about 10:

1 to about 1;

10.

9. A fabric care composition made according to the method of claim 1 wherein the ratio of the fabric softening active to the mixture of glycerol esters is about 2:

1 to about 1;

2.

10. A fabric care composition consisting essentially of a fabric softener active, a delivery enhancing agent comprising a polymer having a net cationic charge and a mixture of glycerol esters, wherein each glycerol ester in the mixture of glycerol esters has the structure of Formula I

11. The composition of claim 10 wherein the composition comprises from about 1% to about 99% of said fabric softening active by weight of the potion.

12. The composition of claim 10 wherein the composition comprises from about 1% to about 99% of said mixture of glycerol esters by weight of the composition.

13. The fabric care composition of claim 10 wherein the composition is substantially free of water.

14. The fabric care composition of claim 10 wherein the fabric softening active is a quaternary ammonium compound.

15. The fabric care composition of claim 14 wherein the fabric softening active is bis-(2 hydroxyethyl)-dimethylammonium chloride fatty acid ester having an average chain length of the fatty acid moieties of from 16 to 20 carbon atoms and an Iodine Value (IV), calculated for the fatty chain, of from 15 to 25.

16. The fabric care composition of claim 14 wherein the fabric softening active is bis-(2-hydroxypropyl)-dimethylammonium methylsulphate fatty acid ester having a molar ratio of fatty acid moieties to amine moieties of from 1.85 to 1.99, an average chain length of the fatty acid moieties of from 16 to 18 carbon atoms and an iodine value of the fatty acid moieties, calculated for the free fatty acid, of from 0.5 to 60.

17. The composition of claim 14 wherein the composition comprises from about 0.5% to about 4.0% of neat perfume by weight of the fabric care composition.

18. The composition of claim 14 wherein the composition comprises a perfume microcapsule.

19. The composition of claim 14 wherein the pH of the composition is from about 2 to about 6.5.

20. The composition of claim 14 wherein the composition comprises from about 0.25% to about 5% by weight of the fabric care composition of a silicone.

21. A method of providing a benefit to a fabric comprising contacting the fabric with the fabric care composition of claim 14.

22. The composition of claim 20 wherein the silicone is a polydimethylsiloxane, an aminosilicone, or an organosiloxane polymer.
