Cosmetic sponge and method for providing a cosmetic sponge
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.
1. A method for providing a cosmetic sponge comprising the steps of:
providing a non-denatured collagen with a fat content less than approximately 7%;
forming an initial mixture comprising said non-denatured collagen and water;
mixing a prepolymer and at least one additive with said initial mixture to form a prepolymer mixture;
reacting said prepolymer mixture to form a resulting polymer foam.
2. The method of claim 1 , further comprising the step of adding an agent from the group consisting of: a cross-linking agent, a catalyst, a surfactant, and combinations thereof.
3. The method of claim 1 , further comprising the step of adding at least one additive 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.
4. The method of claim 1 , wherein the amount of said prepolymer used is between approximately 10% and approximately 50% by weight.
5. The method of claim 1 , wherein the amount of said non-denatured collagen used is between approximately 1% and approximately 25% by weight.
6. The method of claim 1 , further comprising said steps of:
depositing said prepolymer mixture on a releasable bottom paper disposed on a movable carrier;
covering said upper surface of said prepolymer mixture with a releasable top paper as said prepolymer mixture is moved with said movable carrier;
advancing said prepolymer mixture in said top and bottom release paper by moving said carrier;
sizing said resulting polymer foam to a desired thickness to form a sized cosmetic sponge;
removing said top and bottom releasable paper;
drying said sized cosmetic sponge to remove moisture.
7. A method for providing a cosmetic sponge comprising the steps of:
providing a non-denatured collagen with a protein content between approximately 70% and approximately 95%;
forming an initial mixture comprising said non-denatured collagen and water;
mixing a prepolymer and at least one additive with said initial mixture to form a prepolymer mixture;
reacting said prepolymer mixture to form a resulting polymer foam.
8. The method of claim 7 , further comprising the step of adding an agent from the group consisting of: a cross-linking agent, a catalyst, a surfactant, and combinations thereof.
9. The method of claim 7 , further comprising the step of adding at least one additive 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.
10. The method of claim 7 , wherein the amount of said prepolymer used is between approximately 10% and approximately 50% by weight.
11. The method of claim 7 , wherein the amount of said non-denatured collagen used is between approximately 1% and approximately 25% by weight.
12. The method of claim 7 , further comprising said steps of:
depositing said prepolymer mixture on a releasable bottom paper disposed on a movable carrier;
covering said upper surface of said prepolymer mixture with a releasable top paper as said prepolymer mixture is moved with said movable carrier;
advancing said prepolymer mixture in said top and bottom release paper by moving said carrier;
sizing said resulting polymer foam to a desired thickness to form a sized cosmetic sponge;
removing said top and bottom releasable paper;
drying said sized cosmetic sponge to remove moisture.
