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: A keratin hydrogel-filled implantable prosthetic device. One device is a breast implant for augmenting or reconstructing a human breast including an envelope containing a keratin hydrogel. One keratin hydrogel is formed from a solid precursor which forms a keratin hydrogel upon addition of water. One source of keratin is human hair. In one method, an envelope suitable for implantation and a solid keratin hydrogel precursor are provided. The solid can be in fibrous or powder form. The solid precursor can be inserted into the envelope interior. A small incision near the breast can be made and the envelope inserted into the incision. After insertion, water can be injected into the envelope interior, preferably through the incision and through a self-sealing port in the envelope. In one method, the implant is provided as a kit, with the envelope and keratin hydrogel provided. The hydrogel can be injected into the envelope either before or after insertion into the breast area. One kit has a powdered, keratin hydrogel precursor disposed within the envelope interior, awaiting the addition of water, preferably after insertion of the implant into the body.

摘要: A peptide derived from keratin, which can be used as a wound-healing agent. In one method for making the peptide, a keratin source such as human hair is washed, dried, and treated with an oxidizing agent such as peracetic acid for a time and temperature sufficient to swell the keratin and oxidize some of the disulfide bonds to form sulfonic acid groups. The oxidation is believed to form a series of water-soluble peptides. The oxidized hair can be filtered, and the filtrate collected and concentrated under vacuum distillation to a viscous syrup, which can be neutralized with base. The concentrate can be mixed with an excess of a water-miscible organic solvent such as methanol, and the precipitate collected and dried to form the wound-healing agent. The wound-healing agent is believed to include peptides having a molecular weight centered around 850 daltons and having at least one ionizeable group such as sulfonic acid.

摘要: A keratinous wound healing material, preferably derived from the hair of the patient or a compatible donor. Keratin powder can be derived from hair using processing steps including cleaning, suspending in a liquid carrier, homogenizing and removing the liquid. The keratinous material may be applied to the wound in powder form. The keratin can also be applied in sheet form. The keratinous material can be bound with polymeric binder and formed into a sheet by pouring the polymer/binder solution into a mold and flashing off the solvent.
