Abstract
Disclosed is a chitosan microflake which is exceptionally improved in coatability to the skin. The chitosan microflake is manufactured by dissolving chitosan in a weak acidic, aqueous organic acid solution to give a chitosan solution, extracting chitosan from the solution, and solidifying the solution and pulverizing the form film into the microflake which has a width ten fold greater than thickness. With high coatability onto the skin, the chitosan microflake improves the medicinal efficacies of highly pure chitosan, including wound healing, sterilization, prevention or suppression of cicatrix formation, and recuperation from wounds, upon being applied to external traumas such as dermal damages, surgically operated regions and burns. In addition to the medicine and medical industries, the chitosan microflakes can find numerous applications in a broad spectrum of industries, including food, bioengineering, cosmetic, agricultural, chemical engineering, and environmental industries.
