ABSTRACT:
The present invention provides a novel water-soluble keratin derivative and applications thereof. Water-soluble keratin produced by the alkali treatment of feathers, and modified keratin, gives the following useful materials: (1) a high energy wave absorber, (2) a luminescent substrate, (3) a material weatherproofness improver, (4) a water repellant, and (5) a foaming agent.
