Chitosan is a natural linear poly-saccharide derived from chitin, typically sourced from crustacean shells. It is highly valued for its biocompatibility, biodegradability, and high cationic charge density.
Available in various molecular weights and deacetylation degrees, this versatile polymer acts as a powerful flocculant and film-forming agent. It is supplied in high-purity grades for both technical and specialty industrial applications.
This eco-friendly chemical provides superior antimicrobial properties and moisture-retention capabilities. It serves as a sustainable alternative to synthetic polymers in cosmetic formulations and industrial effluent treatment.

Chitosan
Applications
- Water Treatment & Flocculation: Acts as a natural coagulant to effectively remove heavy metals, oils, and suspended organic pollutants from industrial wastewater.
- Cosmetic Film-Forming: Utilized in hair and skin care products to create a breathable protective barrier, enhance moisture retention, and provide natural antimicrobial benefits.
- Agricultural Bio-Stimulant: Applied as a seed coating or foliar spray to protect crops from fungal pathogens and improve systemic resistance and plant growth.
Safety & Risks
Commonly classified as non-hazardous, but fine dust may cause respiratory irritation. Always wear protective gloves, safety goggles, and dust masks during bulk handling. Store in a cool, dry environment away from strong oxidizing agents.
