Abstract: A tissue restoration composition in a colloidal phase, includes a copolymer in which a hydrophobic biocompatible polymer and a hydrophilic biocompatible polymer are polymerized and which is dispersed in water. The colloidal phase has increased viscosity by heating the copolymer dispersed in water. The colloidal phase has a viscosity, by the heating, of 20-200,000 cP.

Abstract: Disclosed are a composition for tissue repair treatment using a non-toxic biocompatible polymer and a method for manufacturing the same. The composition includes a copolymer in which a hydrophobic biocompatible polymer and a hydrophilic biocompatible polymer are polymerized, and having a colloidal phase in which the copolymer is dispersed in water. The method including: preparing a polymer by polymerizing a hydrophobic biocompatible polymer and a hydrophilic biocompatible polymer; and obtaining a colloidal solution by adding the polymer to water.
