Descrição
Hydroxypropyltrimethyl Ammonium Chloride Chitosan(HACC)
HACC is new quaternised chitosan derivative, HACC introduces permanent positively charged quaternary ammonium groups and enhances water solubility, has attracted considerable attention recently as an antibacterial agent over a broad pH range [8–10].
Quaternary ammonium Chitosan (HACC) which was prepared by introducing a quaternary ammonium group on a dissociative hydroxyl group or amino group of the chitosan, exhibited improved water solubility and stronger antibacterial activity relative to chitosan over an entire range of pH values; thus, this quaternary modification increases the potential biomedical applications of chitosan in the field of anti-infection.
