Abstract:
1. A phase invertible composition produced by combining: a substrate comprising a polyamine and a proteinaceous material in a weight ratio having a synergistic viscosity enhancing effect, wherein the combination of the polyamine and the proteinaceous material has a viscosity which is greater than that of either the polyamine or the proteinaceous material alone; and a crosslinking agent, wherein the crosslinking agent causes the polyamine and the proteinaceous material to crosslink and the polyamine and the proteinaceous material crosslink in the presence of the crosslinking agent, wherein said substrate has a kinematic viscosity of about 70 to 200 centistokes, wherein said proteinaceous material is selected from the group consisting of albumin, elastin, fibrin and soluble and insoluble forms of collagen and combinations thereof, and wherein the crosslinking agent comprises a macromolecular crosslinking agent comprising a reaction product of an excess of a liquid aldehyde cross linking agent and a glycosaminoglycan.
