Hydrophilic cross-linked chitosan foam |
| abstract |
An inorganic or organic acid added for dissolving chitosan and a odor due to a crosslinking agent for gelation do not remain, which is highly safe for living bodies, has more uniform air bubbles, and has a preferable appearance. To provide a hydrophilic cross-linked chitosan foam having excellent feel. SOLUTION: Dilute hydrochloric acid or an organic acid having no odor is added to a suspension in which chitosan is dispersed in water, dissolved in a pH range of 5.0 to 6.0, and the solution is cross-linked with an aliphatic diepoxy compound. It is characterized in that the hydrogel is formed by freeze-drying. Preferably, the hydrated gel is formed by rapidly freezing under a condition of −50 ° C. or lower, followed by vacuum drying.
