GEL COMPOSITION AND METHOD FOR PRODUCING SAME

摘要

Disclosed is a gel composition containing a polymer (A) having a repeating unit composed of at least one unsaturated portion and an acid anhydride portion and another repeating unit composed of at least one unsaturated portion and an acid compound portion corresponding to the acid anhydride portion, and a polyhydric alcohol (B). The polymer (A) contains the acid anhydride portion and the acid compound portion corresponding to the acid anhydride portion in a molar ratio of 15/85-85/15. This gel composition exhibits high adhesion to the skin or mucosa, and has excellent gel-forming ability.
