Abstract: The present invention relates to a method of manufacturing a plastic material from a protein source, the method characterized by the following steps; i) treating a protein source such as blood meal with at least one denaturing agent, such as a combination of urea, sodium sulfite and sodium dodecyl sulfate, to break interactions between proteins or portions thereof, and ii) treating the denatured protein source with sufficient pressure and temperature to consolidate the denatured protein source into a plastic material.

Abstract: Disclosed is a hybrid protein-polysaccharide superabsorbent hydrogel. The hydrogel includes two interpenetrating matrices: a first matrix which is an acylated, cross-linked protein matrix, and a second matrix which is an anionic polysaccharidc matrix. The two matrices can be non-cross-linked, or the hydrogel can further include bridging moieties that covalently cross-linking the acylated, cross-linked protein matrix to the anionic polysaccharide matrix.

Abstract: The synthesis of moisture-resistant adhesive polypeptides, conditions for their use, and conditions for controlling characteristics of the crosslinked matrix are disclosed. By specifically manipulating the conditions under which these networks are formed, the characteristics of the networks may be precisely regulated. These manipulatable adhesive networks are water-based, show exceptional bonding capabilities toward wet materials (including biological tissues), and have a variety of biotechnological applications.

Abstract: The present invention is a biodegradable, reversibly-swellable, polyvalent cation-binding, protein hydrogel which comprises an acylated protein matrix in which the acylated protein matrix is crosslinked with a bifunctional crosslinking reagent, and treated with a polar organic solvent, and a method of making the same.
Abstract: The invention includes a method of increasing the substantivity of a personal care composition to hair, skin or nails by preparing a composition of an aqueous phase, a non-aqueous phase and a neutralized amino acid ester that is a reaction product of a neutral amino acid having a non-polar side chain with a long chain fatty alcohol and is represented by formula (I): wherein R1 is an alkyl group; R2 is a linear or branched carbon chain; and the amine group of the amino acid is neutralized with an acid. The composition is substantially free of petrochemicals and/or derivatives of petrochemical materials. The aqueous phase and the non-aqueous phase are emulsified by the neutralized amino acid ester. Other methods and an emulsifiers that is the neutralized amino acid ester are included. Because the neutralized amino acid ester and the compositions do not contain petrochemical-derived ingredient, the products are natural.
