摘要:
A hydratable, highly absorbent keratin solid fiber or powder capable of absorbing a large weight excess of water may be produced by partially oxidizing hair keratin disulfide bonds to sulfonic acid residues and reacting the sulfonic acid residues with a cation. The neutralized suspension can be filtered, washed, and dried, leaving keratin solid which can be shredded into fibers and further ground into powder. Addition of water to the solid produces a hydrogel. The powder or hydrogel may be useful as an absorbent material, as a therapeutic for skin, or as an excipient. The keratin materials can be incorporated into nonwoven films. The hydrogel can be used as a biocompatible viscoelastic filler for implant applications. Another use for the absorbent keratin and keratin hydrogel is as an excipient in pharmaceutical and cosmetic applications.
摘要:
The present invention is directed to a method of modifying feather raw material comprising the steps of: (a) treating feather raw material in a first aqueous solution containing sulphite ions, wherein the treatment is carried out at pH 6 –8, reaching temperature of about 90 degrees Celsius, the treatment lasting at least 30minutes; (b) separating the sulfonated feather material obtained from step (a);(c) treating the sulfonated feather material in a second aqueous solution, wherein the treatment is carried out at pH 1.5 –3.0 and at temperature of 10 –30 degrees Celsius, the treatment lasting at least 5 minutes;and (d) adjusting the pH of the second aqueous solution or the feather material obtained from the second aqueous solution to at least pH4.5 –5.5.The produced protein-rich modified feather product is suitable as an additive for use, e.g., infood industry, animal feeds and cosmetics.

Provided herein are keratin compositions useful for treating ischemia and/or reperfusion injury, such as that associated with myocardial infarct, ischemic stroke, brain trauma such as traumatic brain injury, hypothermia, chronic wounds, and burns.
摘要:
Soluble keratin derivatives are disclosed. The soluble keratin derivatives may include a soluble keratin protein having at least one substituted chemical group at a lysine group, terminal amine group and/or hydroxyl amino acid group of a soluble keratin protein. Soluble keratin derivatives may be formed by succinylation or quaternisation, or by reaction with fatty acid derivatives. The soluble keratin derivatives may be used in personal care formulations, and may also comprise mixtures of several different soluble keratin derivatives.
