Preparation of multifunctional low molecular weight chitosan and its application in cosmetics

摘要

The aim of this study is to elucidate the anti-microbial activity and anti-oxidative actiity of water-soluble chitosan with a molecular weight of 5,000-200,000 Da. Water-soluble chitosans crobial activity on the on teh tested strains by the paper disk method. In the MIC (Minimum Inhibitory Concentration) test, CC-01 (MW = 5,000) with the lower MW showed the higherMIC value than the higher MW chitosan. As the MW of chitosan was increased, its MIC was decreased.
