Pseudo-thermosetting neutralized chitosan composition forming a hydrogel and a process for producing the same |
摘要 |
The composition disclosed is a pseudo-thermosetting neutralized chitosan composition, neutralized with a hydroxylated base, forming a phosphate-free transparent hydrogel at a temperature higher than 5° C. Said composition contains a homogeneously reacetylated chitosan derived from a chitosan having a deacetylation degree of 80-90%, having a molecular weight of not smaller than 200 kDa and a deacetylation degree of 30-60%, and may further contain a diol. Said composition may be used as a drug delivery system.
