Abstract: Disclosed is an anti-adhesion agent composition which uses a high molecular weight compound having biocompatibility and an oil derived from animals, plants, and minerals so as to improve low viscosity and low strength, which are problems of existing anti-adhesion agents, and prevent adhesion between living tissues. The anti-adhesion composition according to the present disclosure performs a physical barrier function through simple mixing of a polymer material, serving as a physical barrier in its anti-adhesion effect, and a solvent, and remains in the body for a certain period of time, then decomposes, absorbs, and is excreted. The anti-adhesion composition does not interfere with the healing of the wound after surgery, and exhibits an excellent effect of convenient application to the surgical site.
