Chitosan cross-linked collagen-glycosaminoglyan (CCGM) is an artificial skin substitute made to form a sponge like dimensional matrix. It can be used to facilitate reconstruction of dermal tissue when applied on large wounds such as severe burns. In order to study the toxicological effects of CCGM the cytotoxicity, local irritation and skin sensitization test were carried out according to the standards of ISO 10993. In the cytotoxicity test utilizing LDH and MTT test, both the CCGM and its extract had no toxicity of Balb/c 3T3 cells. The local irritatioin test on rabbit skin demonstrated that CCGM did not promote any harmful when directly applied on skin. In addition, it did not elicit any allergic reaction in the guinea pig maximization test. Based on these results, it is suggested that CCGM is a material without cytotoxicity, local irritation and allergenicity.
