  • Hydratable Keratin Compositions
    Publication number: 20110196129
    Abstract: Keratin hydratable absorbents and films are fabricated with simple, repeatable processes. Freeze drying produces a material with instantaneous water absorption to over 20 times its weight in water. Films produced are flexible and uniform with water absorption 7-8 times the original weight.
