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 layered composite material for use as a cosmetic sponge comprising:
a. A cover layer permeable to air, gases, and aqueous liquid solutions; and a foam layer comprising a polymer foam, a non-denatured collagen, and at least one additive;
wherein the non-denatured collagen includes a fat content less than 7%; and
wherein the cover layer includes material fibers;
b. Wherein a first surface of said foam layer is joined to said cover layer by needle punching, such that material fibers of said cover layer penetrate into and sometimes through said foam layer.
2. The layered composite material of claim 1 , wherein said foam layer is more hydrophilic than said cover layer.
3. The layered composite material of claim 1 wherein said cover layer comprises a material selected from the group consisting of a randomized polyester fiber material, a non-woven material, a non-woven fiber web, and a felted non-woven fiber web.
4. The layered composite material of claim 1 , further comprising at least one additional cover layer joined to at least one additional surface of said foam layer by needle punching, such that material fibers of said cover layer penetrate into and sometimes through said foam layer.
5. The layered composite material of claim 1 , wherein the non-denatured collagen further includes a fiber length less than approximately 10 millimeters.
6. The layered composite material of claim 1 , wherein the non-denatured collagen further includes a moisture content less than 30%.
7. The layered composite material of claim 1 , wherein the non-denatured collagen further includes a protein content between 70% and 95%.
8. The layered composite material of claim 1 , further including a superabsorbent polymer.
