MEDICAL/COSMETIC MATERIAL AND ADHESION PREVENTING MATERIAL

摘要

Provided is a medical/cosmetic material in which characteristics inherent in polyanionic polysaccharides, which are starting materials, are maintained, that is highly safe because there is no need to use chemical cross-linking agents during production, and that is capable of uniformly retaining a water-insoluble polyanionic polysaccharide powder on an affected area. This medical/cosmetic material comprises: a base including a water-soluble salt of a first polyanionic polysaccharide; and a powder that is dispersed in the base, and that is formed by subjecting a powder of a water-soluble salt of a second polyanionic polysaccharide to a water-insolubilization treatment with a treatment liquid including an acid anhydride.
