  • Applications

    Chitosan, 2-hydroxypropyl ether (CAS 84069-44-3) is a water-soluble derivative of chitosan used as a bio-based polymer additive across several industries. In cosmetics and personal care, it acts as a film-forming agent, thickener and stabilizer in gels, shampoos and skin-care formulations. In coatings and inks, it serves as a film-forming additive and rheology modifier for water-based systems, improving gloss and processability. In agriculture and food processing, it can be used as an edible coating for fruits and vegetables or as a seed/fruit coating to extend freshness and reduce moisture loss. In industrial manufacturing and water treatment, it functions as a biodegradable flocculant and stabilizer in suspensions, aiding clarification and sludge settling. In polymers/plastics and adhesives, it acts as a rheology modifier and compatibilizer in biopolymer blends and as a bio-based binder in environmentally friendly formulations.
