Definitions

  • the well-known wound protecting dressings contain standard chitosan in the form of organic or inorganic salts soluble in water or diluted organic acids, or derivatives of chitin and chitosan soluble in water or organic solvents. Preparation of chitin or chitosan derivatives needs special complicated technologies as well as brings some problems for processing and purification.
  • a standard chitosan saltas soluble in water and diluted organic acids having also acidic reaction, usually with pH 3 - 5, cause an irritation or allergic reaction of wound healing or burned place.
  • the standard chitosan salt film formed on a skin does not resist against water and will be easily dissolved into washing water or moisture. This type of dressing needs several repetitions to obtain suitable healing.
