Abstract

This disclosure relates to personal grooming apparatus that include coatings on the surface thereof that incorporate calcium carbonate derived from the shell of a mollusk and/or from a mollusk pearl. Other aspects of the present disclosure relate to methods for producing such apparatus, and methods of grooming the hair or skin of an individual.

Claims

1. A personal grooming apparatus, the apparatus having:

a substrate;

a coating disposed on the substrate, the coating comprising calcium carbonate and having a thickness of from about 3 μ

m to about 100 μ

m, the calcium carbonate being derived from the shell of a mollusk or from a mollusk pearl, the calcium carbonate containing coating having a surface for contacting skin or hair during use of the apparatus; and

,

a base coating disposed between the substrate and the calcium carbonate containing coating, the base coating having a thickness of from about 10 μ

m to about 30 μ

m.

2. The personal grooming apparatus as set forth in claim 1 wherein the calcium carbonate containing coating comprises conchiolin protein.

3. The personal grooming apparatus as set forth in claim 2 wherein the conchiolin forms a matrix in which calcium carbonate is embedded.

4. The personal grooming apparatus as set forth in claim 2 wherein the calcium carbonate containing coating comprises at least about 0.001 wt % conchiolin.

5. The personal grooming apparatus as set forth in claim 1 wherein the calcium carbonate containing coating comprises nacre.

6. The personal grooming apparatus as set forth in claim 1 wherein the calcium carbonate containing coating comprises at least about 0.01 wt % calcium carbonate derived from the shell of a mollusk or from a mollusk pearl.

7. The personal grooming apparatus as set forth in claim 1 wherein the calcium carbonate containing coating comprises a component selected from one or more metal oxides, tourmaline and mixtures thereof.

8. The personal grooming apparatus as set forth in claim 1 wherein the base coating does not comprise calcium carbonate.

9. The personal grooming apparatus as set forth in claim 1 wherein the thickness of the calcium carbonate containing coating is from about 5 μ

m to about 25 μ

m.

10. The personal grooming apparatus as set forth in claim 1 wherein the average particle size of the calcium carbonate is less than about 50 μ

m.

11. The personal grooming apparatus as set forth in claim 1 wherein the calcium carbonate contains both nano-scale and micro-scale particles.

12. The personal grooming apparatus as set forth in claim 11 wherein at least about 99% of the total nano-scale particles have a particle size of at least about 5 nm and at least about 75% of the nano-scale particles have a particle size of from about 40 nm to about 80 nm.

13. The personal grooming apparatus as set forth in claim 1 wherein the mollusk is an oyster.

14. The personal grooming apparatus as set forth in claim 1 wherein the apparatus is selected from the group consisting of a hair straightener, hair curler, curling iron, hot roller, a device for securing hair, shaver, clipper, friction-reducing strips or pads, brush, comb, wipe, cloth and exfoliating pads.

15. The personal grooming apparatus as set forth in claim 1 wherein the thickness of the calcium carbonate containing coating is from about 5 μ

m to about 100 μ

m.

16. A personal grooming apparatus, the apparatus having a substrate and a coating disposed on the substrate, the coating comprising calcium carbonate, the calcium carbonate being derived from the shell of a mollusk or from a mollusk pearl, the calcium carbonate containing coating having a surface for contacting skin or hair during use of the apparatus, the calcium carbonate comprising both nano-scale and micro-scale particles with at least about 99% of the total nano-scale particles having a particle size of at least about 5 nm and at least about 75% of the nano-scale particles having a particle size of from about 40 nm to about 80 nm.

17. The personal grooming apparatus as set forth in claim 16 wherein the calcium carbonate containing coating comprises conchiolin protein.

18. The personal grooming apparatus as set forth in claim 17 wherein the conchiolin forms a matrix in which calcium carbonate is embedded.

19. The personal grooming apparatus as set forth in claim 17 wherein the calcium carbonate containing coating comprises at least about 0.001 wt % conchiolin.

20. The personal grooming apparatus as set forth in claim 16 wherein the calcium carbonate containing coating comprises nacre.

21. The personal grooming apparatus as set forth in claim 16 wherein the calcium carbonate containing coating comprises at least about 0.01 wt % calcium carbonate derived from the shell of a mollusk or from a mollusk pearl.

22. The personal grooming apparatus as set forth in claim 16 wherein the calcium carbonate containing coating comprises a component selected from one or more metal oxides, tourmaline and mixtures thereof.

23. The personal grooming apparatus as set forth in claim 16 further comprising a base coating disposed between the substrate and the calcium carbonate containing coating.

24. The personal grooming apparatus as set forth in claim 23 wherein the base coating does not comprise calcium carbonate.

25. The personal grooming apparatus as set forth in claim 16 wherein the thickness of the calcium carbonate containing coating is from about 3 μ

m to about 100 μ

m.

26. The personal grooming apparatus as set forth in claim 16 wherein the thickness of the calcium carbonate containing coating is from about 5 μ

m to about 100 μ

m.

27. The personal grooming apparatus as set forth in claim 16 wherein the average particle size of the calcium carbonate is less than about 50 μ

m.

28. The personal grooming apparatus as set forth in claim 16 wherein the mollusk is an oyster.

29. The personal grooming apparatus as set forth in claim 16 wherein the apparatus is selected from the group consisting of a hair straightener, hair curler, curling iron, hot roller, a device for securing hair, shaver, clipper, friction-reducing strips or pads, brush, comb, wipe, cloth and exfoliating pads.
