Water-soluble N-carboxybutyl-chitosan was synthesized by reacting chitosan with levulinic acid and sodium borohydride. The moisture-absorption and moisture-retention capacity of chitosans with different degree of deacetylation and different molecular weight and N-carboxybutyl-chitosan were studied. The results indicated that chitosan with degree of deacetylation 50% had the best ability of moisture-absorption and retention and N-carboxybutyl-chitosan showed a quite same moisture-absorption capacity to that of hyaluronic acid when their molecular mass was at 5.0×105 level.
