Synonym(s): Deacetylated chitin, Poly(D-glucosamine)

Description

Chitosan: MP's chitosan is a partially de-acetylated chitin formed by the reaction of chitin with concentrated alkali. A brief description of chitin will help you understand the nature of chitosan. Chitin is a high molecular weight linear polymer of anhydro-N-acetyl-glucosamine. Chitin occurs in nature as part of the protective coating of some invertebrates.The availability of this nature endowed ploymer opens up many interesting possibilities of applications where a high molecular weight cationic polymer is suitable. Chitosan polymer is biodegradable, with low toxicity, if any.

Features

High purity and consistent quality: ≥ 90% deacetylated chitin ensures strong cationic activity and reproducible performance batch-to-batch.
Low molecular weight (~10–20 kDa): Suitable for applications requiring soluble, easily processable chitosan (e.g., film formation, coating, hydrogel preparation).
Biocompatible, biodegradable and low-toxicity biopolymer: Naturally derived from chitin; safe for many bio‑based and environmental applications.
Rich functional groups (free amino groups): Provide strong bio‑adhesion, ability to bind negatively charged surfaces (cells, tissues, pollutants), enabling versatile chemical modifications and derivative synthesis.
Environmentally friendly and sustainable: Being a renewable polymer often sourced from crustacean shell waste, it supports biodegradation and circular‑economy materials development.

Applications

Biomedical research & wound healing / tissue engineering: As raw material for hydrogels, sponges, films, scaffolds or coatings. Its antimicrobial, hemostatic (platelet‑aggregating), and tissue‑regenerative properties make it suitable for wound dressings, burn treatments, soft tissue repair, and as a base for drug‑delivery carriers.
Drug delivery / formulation research: Because of its bioadhesiveness and biocompatibility, chitosan can be processed into nanoparticles, microspheres, or coatings to deliver actives in research contexts.
Water treatment and environmental remediation: As a biodegradable cationic polymer, chitosan is widely used for flocculation, heavy metal or pollutant adsorption, wastewater purification, and removal of turbidity or dyes — a sustainable alternative to synthetic polymers.
Bioplastics, biodegradable films, coatings & packaging: It can serve as a film‑forming or matrix polymer — useful for environmentally friendly packaging, composite materials, or sustainable plastics when blended with starch, gelatin or other biopolymers.
Agriculture / horticulture: Used as a natural plant biostimulant or biocontrol agent (seed treatment, crop protection), enhancing disease resistance and plant defense, aligning with eco‑friendly farming practices.
