Wound care products containing keratin
The invention relates to a would care product that provides a biochemical environment around a wound to promote wound healing. The wound care product includes a keratin protein fraction material in which the protein fraction is intact, is from the intermediate filament protein family or the high sulfur protein family and in which the protein fraction is S-sulfonated. The invention also described a method of making a wound care product.
1. A wound care hydrogel comprising S-sulfonated keratin associated with a water soluble polymer through hydrogen bonding and further comprising a protein cross-linking agent.
2. The wound care hydrogel of claim 1 where the S-sulfonated keratin is S-sulfonated keratin intermediate filament protein, the water soluble polymer is selected from the group consisting of polyvinyl alcohol and polyvinyl pyrrolidone and mixtures thereof, and the protein crosslinking agent is selected from the group consisting of glutaraldehyde, formaldehyde, carbodiimide, 2,5-hexanedione, diimidate, bisacrylamide and mixtures thereof.
3. The wound care hydrogel of claim 2 where the protein crosslinking agent comprises glutaraldehyde.
4. A wound care hydrogel comprising S-sulfonated keratin associated with a water soluble polymer through hydrogen bonding.
5. The wound care hydrogel of claim 4 where the S-sulfonated keratin is S-sulfonated keratin intermediate filament protein and the water soluble polymer is selected from the group consisting of polyvinyl alcohol and polyvinyl pyrolidone and mixtures thereof.
6. A method for treating a wound comprising applying a wound site a wound care hydrogel according to claim 1 .
7. A method for treating a wound comprising applying a wound site a wound care hydrogel according to claim 2 .
8. A method for treating a wound comprising applying a wound site a wound care hydrogel according to claim 3 .
9. A method for treating a wound comprising applying a wound site a wound care hydrogel according to claim 4 .
