Abstract

This invention relates to a cosmetic sponge and a method of providing a cosmetic sponge incorporating a non-denatured collagen and other additives for skin care, cleaning, and cosmetic application.

Claims (22)

1. A cosmetic sponge comprising a polymer foam, a non-denatured collagen, and at least one additive, and wherein the non-denatured collagen further includes a fat content less than approximately 7%.

2. The cosmetic sponge of claim 1 , wherein the non-denatured collagen further includes a moisture content less than approximately 30%.

3. The cosmetic sponge of claim 1 wherein the non-denatured collagen is prepared under pH conditions ranging from approximately 13 to approximately 3.

4. The cosmetic sponge of claim 1 wherein the non-denatured collagen is prepared under pH conditions ranging from approximately 9 to approximately 5.

5. The cosmetic sponge of claim 1 wherein the at least one additive is selected from the group consisting of: skin care agents, hydrocolloid absorptive agents, medicaments, proteins, enzymes, nucleic acids, vitamins, soaps, hemostatic agents, antibacterial agents, antifungal agents, surfactants, pH buffers, mineral salts, trace elements, plant extracts, animal extracts, disinfecting and sterilizing agents, and combinations thereof.

6. The cosmetic sponge of claim 1 , wherein the sponge is a reaction product of a mixture comprising:

a predetermined amount of non-denatured collagen; a predetermined amount of a prepolymer; and at least one additive.

7. The cosmetic sponge of claim 6 , wherein the amount of prepolymer is between approximately 10% and approximately 50% by weight.

8. The cosmetic sponge of claim 6 , wherein the amount of non-denatured collagen is between approximately 1% and approximately 25% by weight.

9. The cosmetic sponge of claim 1 further comprising an agent from the group consisting of: a cross-linking agent, a catalyst, a surfactant, and combinations thereof.

10. The cosmetic sponge of claim 1 , wherein the non-denatured collagen further includes a fiber length less than approximately 10 mm.

11. A cosmetic sponge comprising a polymer foam, a non-denatured collagen, and at least one additive, and wherein the non-denatured collagen further includes a protein content between approximately 70% and approximately 95%.

12. The cosmetic sponge of claim 11 wherein the non-denatured collagen is prepared under pH conditions ranging from approximately 13 to approximately 3.

13. The cosmetic sponge of claim 11 wherein the non-denatured collagen is prepared under pH conditions ranging from approximately 9 to approximately 5.

14. The cosmetic sponge of claim 11 wherein the at least one additive is selected from the group consisting of: skin care agents, hydrocolloid absorptive agents, medicaments, proteins, enzymes, nucleic acids, vitamins, soaps, hemostatic agents, antibacterial agents, antifungal agents, surfactants, pH buffers, mineral salts, trace elements, plant extracts, animal extracts, disinfecting and sterilizing agents, and combinations thereof.

15. The cosmetic sponge of claim 11 , wherein the sponge is a reaction product of a mixture comprising:

a predetermined amount of non-denatured collagen; a predetermined amount of a prepolymer; and at least one additive.

16. The cosmetic sponge of claim 15 , wherein the amount of prepolymer is between approximately 10% and approximately 50% by weight.

17. The cosmetic sponge of claim 15 , wherein the amount of non-denatured collagen is between approximately 1% and approximately 25% by weight.

18. The cosmetic sponge of claim 11 further comprising an agent from the group consisting of: a cross-linking agent, a catalyst, a surfactant, and combinations thereof.

19. The cosmetic sponge of claim 11 , wherein the non-denatured collagen further includes a fiber length less than approximately 10 mm.

20. The cosmetic sponge of claim 11 , wherein the non-denatured collagen further includes a moisture content less than approximately 30%.
