Patent ID: 7754229

Claim:
A method for producing an aqueous gel composition comprising a biopolymer crosslinked to a binding agent, said method comprising the steps of: a) providing at least one biopolymer selected from the group consisting of polyhydroxyalkanoate (PHA), polylactide (PLA), polyglycoside (PGA), polylactideglycolide (PLGA), and polycaprolactone (PCL), in the form of particles in suspension in an aqueous medium forming a latex; b) contacting said latex of step a) with said binding agent wherein said binding agent is a molecule comprising at least one hydrophilic domain and a hydrophobic domain, for a time and conditions sufficient to form an soluble complex solution of biopolymer particles mixed with said binding agent; and c) heating said soluble complex solution of step b) at between 27° C. and 70° C. for a time sufficient to crosslink said biopolymer and binding agent to increase viscosity of said solution from step b) to form said gel; wherein said hydrophilic domain is polyethylene glycol, and said hydrophobic domain is a fatty acid.
