| 20090069541 | PRODUCTION OF BIOPOLYMER FILM, FIBRE, FOAM AND ADHESIVE MATERIALS FROM SOLUBLE S-SULFONATED KERATIN DERIVATIVES - Film, fibre, foam and adhesive materials are produced from soluble S-sulfonated keratins. Once formed, the films, fibres, foams or adhesives are treated to modify the properties of the materials, in particular to improve the wet strength of the materials. Treatments used include removal of the S-sulfonate group by treatment with a reducing agent, treatment with an acid or treatment with a common protein crosslinking agent or treatment with a reduced form of keratin or keratin protein. The films are made by solvent casting a solution of S-sulfonated keratin proteins, the foam made by freeze-drying a solution of S-sulfonated keratin proteins and the fibres made by extruding a solution of a S-sulfonated keratin protein. | 03-12-2009 |
| 20090105456 | Porous keratin construct and method of making the same - The invention relates to a porous keratin construct material comprising keratin protein for use in wound healing applications. The porous keratin construct is capable of bio-absorbing into a wound to promote wound healing. The rate at which the construct bio-absorbs into the wound may be controlled altered by controlling the degree of disulfide cross-linking between the keratin proteins in the porous keratin construct. The invention is also related to a method of making the porous keratin construct. | 04-23-2009 |
| 20100069612 | WATER-SOLUBLE KERATIN DERIVATIVE AND USE THEREOF - 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. | 03-18-2010 |
| 20110196129 | Hydratable Keratin Compositions - 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. | 08-11-2011 |
| 20120130048 | PROCESS FOR EXTRACTING KERATIN - The present invention relates to a process for extracting keratin from poultry feather, and provides a quicker process thus allowing large-scale productions of the keratin production to be carried out in timely manner thus increasing the productivity and efficiency of such process. | 05-24-2012 |
| 20140114053 | Electrophoresis Separation Methods - An improved method of separating a macromolecule by isoelectric focusing comprising subjecting the macromolecule to electrophoresis in an isoelectric-focusing medium including a substantially thiol-free reducing agent, preferably a trivalent phosphorous compound and more preferably tributyl phosphine, the improvement being the solubility and focusing of the macromolecule is enhanced compared to isoelectric focusing of the same macromolecule in a similar isoelectric-focusing medium containing a thiol-reducing agent. | 04-24-2014 |
| 20140235824 | Method to Wash Greasy Wool, A Method to Separate Lanolin from the Said Greasy Wool, Wool and Lanolin Obtainable by These Methods - A method to wash wool containing lanolin and impurities includes the steps of providing a volume of an aqueous liquid at a temperature below a melting temperature of the lanolin, soaking the wool in the volume of the liquid, creating air bubbles in the liquid and allowing the air bubbles to pass through the wool to attach the impurities, removing the air bubbles and attached impurities from the volume, and separating lanolin from wool containing lanolin and impurities, along with the wool and lanolin obtainable by this method. | 08-21-2014 |
| 20150065686 | METHOD FOR MAKING A FIBRE COMPRISING NATURAL FIBRE NANOPARTICLES - A method for making natural fibre products comprising embrittling natural fibres and breaking the embrittled fibres into nanoparticles, forming a suspension of the fibre nanoparticles in a spinnable liquid, and spinning fibre from the suspension. The method may be used to make fibres having the dimensions and properties of cashmere. | 03-05-2015 |
| 20150080552 | METHODS FOR EXTRACTING KERATIN PROTEINS - Described herein are methods to produce keratin protein-based biomaterials, the parameters required to achieve improved extraction, the parameters required to improve isolation, the parameters of lyophilization and the grinding process to achieve consistent particulate sizes of protein materials. | 03-19-2015 |
| 20150368308 | METHOD OF PREPARING A KERATIN-BASED BIOMATERIAL AND KERATIN-BASED BIOMATERIAL FORMED THEREOF - Method of preparing a keratin-based biomaterial is provided. The method comprises a) reacting keratin with a polymer having at least one of an amine and carboxylic functional group in the presence of a carbodiimide cross-linking agent to form a cross-linked keratin-polymer material; and b) freeze drying the cross-linked keratin-polymer material to form the keratin-based bio-material. A keratin-based biomaterial thus prepared is also provided. | 12-24-2015 |
