Abstract

Described herein, are compositions comprising a soluble quaternary ammonium polymer/polyphosphate complex made by combining ingredients comprising a quaternary ammonium polymer and polyphosphates having 2 or more phosphate units. Methods of making and using these compositions are also described.

First claim

The invention claimed is:

1. A personal care composition, comprising:
a soluble quaternary ammonium polymer polyphosphate complex formed by combining:
at least one quaternary ammonium polymer; and
at least one polyphosphate having 2 or more phosphate units; and

a solvent;
wherein the personal care composition is at least one of an antiperspirant or a deodorant, and
wherein the personal care composition comprises from 20% to 50% by weight of the at least one polyphosphate.

2. The personal care composition of claim 1 , wherein the at least one quaternary ammonium polymer is a poly(N-trialkylaminoalkyl)acrylamide.

3. The personal care composition of claim 1 , wherein the at least one quaternary ammonium polymer is polyacrylamidopropyltrimonium chloride.

4. The personal care composition of claim 3 , wherein the polyacrylamidopropyltrimonium chloride has a number average molecular weight greater than or equal to 100,000 daltons and less than or equal to 500,000 daltons.

5. The personal care composition of claim 1 , wherein the solvent is an aqueous solvent.

6. The personal care composition of claim 1 , wherein the at least one polyphosphate has 3 or more phosphate units.

7. The personal care composition of claim 6 , wherein the at least one polyphosphate has greater than or equal to 6 phosphate units and less than or equal to 50 phosphate units.

8. The personal care composition of claim 1 , wherein the at least one polyphosphate comprises sodium tripolyphosphate.

9. The personal care composition of claim 1 , wherein the at least one polyphosphate comprises sodium polymetaphosphate.

10. The personal care composition of claim 1 , wherein the personal care composition is substantially free of aluminum complexes, or is substantially free of zirconium complexes, or is substantially free of both aluminum and zirconium complexes.

11. A method of occluding pores of a subject, the method comprising:
applying the personal care composition of claim 1 to skin of the subject.

12. The personal care composition of claim 6 , wherein the at least one polyphosphate has about 23 phosphate units.

13. The personal care composition of claim 1 , wherein the at least one quaternary ammonium polymer is a poly(N-trialkylaminoalkyl)acrylamide, and
wherein the at least one polyphosphate has greater than or equal to 6 phosphate units and less than or equal to 50 phosphate units.

14. The personal care composition of claim 13 , wherein the at least one quaternary ammonium polymer is polyacrylamidopropyltrimonium chloride.

15. The personal care composition of claim 13 , wherein the at least one polyphosphate comprises sodium polymetaphosphate.

16. The personal care composition of claim 14 , wherein the at least one polyphosphate comprises sodium polymetaphosphate.

17. The personal care composition of claim 1 , wherein the solvent is a non-aqueous solvent.

18. A personal care composition, comprising:
a soluble quaternary ammonium polymer polyphosphate complex formed by combining in a solvent:
at least one quaternary ammonium polymer; and
at least one polyphosphate having 2 or more phosphate units;

wherein the personal care composition comprises from 20% to 50% by weight of the at least one polyphosphate, and
wherein the personal care composition is a cosmetic.

19. The personal care composition of claim 18 , wherein the solvent is an aqueous solvent.

20. The personal care composition of claim 1 , wherein the antiperspirant or deodorant further comprises a carrier in the form of a stick, a gel, a roll on, or an aerosol.
