Abstract

The present invention relates to compositions, kits, and films formed therefrom which are useful as cosmetic or therapeutic agents, particularly as polishes for mammalian nails, as well as methods of their use. More particularly, the present invention relates to fast-drying compositions which enhance long wear through their fast-drying properties. When applied to mammalian nails, the present fast-drying compositions exhibit a 5% Diluent Content Time of less than about 38 minutes and or exhibit a 5% Diluent Content Time of less than about 44 minutes and has an Initial Slope greater than about 2.25.

Claims

1. A fast-drying composition suitable for use as a nail polish for mammalian nails comprising:

(a) a film-forming, water-borne polymer; and

(b) a liquid diluent comprising;

(i) at least about 20%, by weight of the composition, of a volatile organic solvent; and

(ii) at least about 4% water;

wherein the composition exhibits a 5% Diluent Content Time of less than about 38 minutes.

2. A composition according to claim 1 wherein the polymer is a water-insoluble polymer selected from the group consisting of polyurethanes, polyacryls, polymethacryls, urethane-acryl copolymers, styrene-acryl copolymers, and mixtures thereof.

3. A composition according to claim 2 wherein the polymer is a polyurethane.

4. A composition according to claim 1 exhibiting a 5% Diluent Content Time of less than about 36 minutes.

5. A composition according to claim 1 exhibiting a 5% Diluent Content Time of less than about 34 minutes.

6. A composition according to claim 1 exhibiting a 5% Diluent Content Time of less than about 32 minutes.

12. A kit suitable for use as a nail polish for mammalian nails, the kit comprising two or more different compositions wherein each composition comprises a film-forming polymer and a liquid diluent, wherein at least one of the compositions is a composition according to claim 1.

13. A kit according to claim 12 wherein the water-borne polymer is a water-insoluble polymer selected from the group consisting of polyurethanes, polyacryls, polymethacryls, urethane-acryl copolymers, styrene-acryl copolymers, and mixtures thereof.

14. A kit according to claim 13 wherein the water-borne polymer is a polyurethane.

15. A kit according to claim 12 comprising a fast-drying composition and a topcoat composition wherein:

(a) wherein the water-borne polymer of the fast-drying composition is selected from the group consisting of polyurethanes, polyacryls, polymethacryls, urethane-acryl copolymers, styrene-acryl copolymers, and mixtures thereof; and

(b) the topcoat composition comprises a film-forming water-insoluble polymer selected from the group consisting of polyurethanes, polyacryls, polymethacryls, polystyrene-polyacryl mixtures, styrene-acryl copolymers, siloxane-urethane copolymers, cellulosic polymers, polyesters, polyurethane-polymethacryl mixtures, silicone-acryl copolymers, vinyl acetate polymers, and mixtures thereof.

16. A kit according to claim 12 comprising a basecoat composition and a topcoat composition wherein:

(a) wherein the water-borne polymer of the fast-drying composition is selected from the group consisting of polyurethanes, polyacryls, polymethacryls, urethane-acryl copolymers, styrene-acryl copolymers, and mixtures thereof; and

(b) the topcoat composition comprises a film-forming water-insoluble polymer selected from the group consisting of cellulosic polymers, polyurethanes, polyacryls, polymethacryls, polysiloxanes, and mixtures thereof.

17. A kit according to claim 15 further comprising a midcoat composition comprising a film-forming water-insoluble polymer selected from the group consisting of cellulosic polymers, polyurethanes, polyacryls, polymethacryls, polysiloxanes, and mixtures thereof.

18. A kit according to claim 12 wherein the 5% Diluent Content Time is less than about 36 minutes.

19. A kit according to claim 12 wherein the 5% Diluent Content Time is less than about 34 minutes.

20. A kit according to claim 12 wherein the 5% Diluent Content Time is less than about 32 minutes.

7. A composition suitable for use as a nail polish for mammalian nails comprising:

(a) a film-forming, water-borne polymer; and

(b) a liquid diluent comprising;

(i) at least about 20%, by weight of the composition, of a volatile organic solvent; and

(ii) at least about 4% water;

wherein the composition exhibits a 5% Diluent Content Time of less than about 44 minutes and an Initial Slope greater than about 2.25.

8. A composition according to claim 7 wherein the polymer is a water-insoluble polymer selected from the group consisting of polyurethanes, polyacryls, polymethacryls, urethane-acryl copolymers, styrene-acryl copolymers, and mixtures thereof.

9. A composition according to claim 8 wherein the polymer is a polyurethane.

10. A composition according to claim 7 exhibiting an Initial Slope of greater than about 2.75.

11. A composition according to claim 7 exhibiting an Initial Slope of greater than about 3.00.

21. A kit suitable for use as a nail polish for mammalian nails, the kit comprising two or more different compositions wherein each composition comprises a film-forming polymer and a liquid diluent, wherein at least one of the compositions is a composition according to claim 7.

22. A kit according to claim 21 wherein the Initial Slope is greater than about 2.75.

23. A kit according to claim 21 wherein the Initial Slope is greater than about 3.00.

24. A method of coating mammalian nails with a nail polish film, wherein the method comprises the steps of:

(i) applying a composition according to claim I contiguously to the nail; and

(ii) removing sufficient liquid diluent from the composition to form a substantially dry layer.

25. A method according to claim 24 further comprising the steps of:

(iii) applying a second composition to the nail, wherein the second composition comprises a film-forming polymer and a liquid diluent;

(iv) removing sufficient liquid diluent from the second composition to form a substantially dry layer;
