Chitosan Hydrochloride
Type: Water Souble Chitosan
CAS Number: 70694-72-3
Molecular Formula: (C₆H₁₁NO₄·HCl)ₙ
Appearance: White to off-white powder
Solubility: Freely soluble in water
Overview
Chitosan Hydrochloride is a water-soluble derivative of chitosan produced through neutralization with hydrochloric acid. It retains the biocompatibility, biodegradability, and antimicrobial properties of natural chitosan while offering superior solubility in water without acidic solutions. Ideal for pharmaceuticals, cosmetics, food preservation, and biomedical applications including wound healing, drug delivery, and tissue engineering.
