Abstract: Disclosed herein is a hydrogel composition that includes a crosslinked collagen polymer, a carboxymethyl cellulose derivative, an aqueous sodium chloride solution, a humectant, and an antimicrobial agent. The crosslinked collagen polymer has collagen, a hydrophilic polyether, and a dicarbamate group linking the collagen to the hydrophilic polyether. The carboxymethyl cellulose derivative is selected from the group consisting of carboxymethyl cellulose, an alkali metal salt of carboxymethyl cellulose, an ammonium salt of carboxymethyl cellulose, and combinations thereof. The humectant is selected from the group consisting of glycerin, propylene glycol, and a combination thereof. The antimicrobial agent is a combination of glycine betaine and polyhexamethylene biguanide hydrochloride.

Abstract: A liquid dressing includes a solvent and a film-forming polymer that is dissolved in the solvent and that is made by a process including: providing an alkoxy group-containing silicone resin which is obtained by subjecting an orthosilicate compound and an acidic aqueous solution to a hydrolysis and polymerization reaction; providing an isocyanate group-containing prepolymer which is obtained by reacting a diisocyanate compound with a hydrophilic polyether diol; and subjecting the alkoxy group-containing silicone resin and the isocyanate group-containing prepolymer to a polymerization reaction so as to obtain the film-forming polymer.
