General description

KiOmedine-CSU® is an ultra-pure chitosan of non-animal origin, produced from white mushrooms (Agaricus bisporus), in accordance with cGMP.
The crystalline structure is in the alpha form. The linkage between glucosamine units is beta(1,4).

Application

Forms gels with multivalent anions. Gives clear solutions that dry to strong, clear films.
Ideal for wound healing and hemostasis; biosurgery and ophthalmology, scaffold and cell therapy; and drug delivery and vaccines

Features and Benefits

Biocompatible, antibacterial and environmentally friendly polyelectrolyte with a variety of applications including water treatment, chromatography, additives for cosmetics, textile treatment for antimicrobial activity, novel fibers for textiles, photographic papers, biodegradable films, biomedical devices, and microcapsule implants for controlled release in drug delivery.

Physical properties

Degree of acetylation: ≤40 mol. %
