Quaternary Chitosan — Advanced Bioactive Performance from a Plant-Based Source
Scientifically developed. Mushroom-derived.
Ultra-soluble.
Engineered for breakthrough applications in medical, food safety, water treatment, agriculture, and clean-label manufacturing.
What Is Quaternary Chitosan?
Quaternary Chitosan is a highly water-soluble, positively charged derivative of chitosan that has been chemically modified to enhance its antimicrobial, antiviral, and functional performance — all without sacrificing biocompatibility or environmental safety.
At Quaternary Chitosan, we specialize in premium-quality, mushroom-sourced quaternary chitosan designed for use in:
pH-neutral environments where conventional chitosan fails
Clean-label supplements, food packaging, and medical coatings
Industrial applications requiring high solubility, stable viscosity, and non-toxicity
We supply research-grade and bulk volumes to scientists, formulators, and R&D innovators looking to build safer, smarter, and more sustainable solutions.
Why Choose Our Quaternary Chitosan?
Mushroom-Based & Vegan
Avoids shellfish allergens, animal byproducts, and heavy metals — perfect for clean-label.
Stable in Neutral pH
Unlike traditional chitosan, ours works in pH 6–8, making it ideal for food and skin use.
Superior Antimicrobial
Inhibits bacteria, mold, and viruses — ideal for wound care, sanitizers, and films.
Highly Water-Soluble
No heating or acids required — dissolves instantly for spray, gel, or capsule formulations.
Detox and Fat Binding
Binds fats, oils, and heavy metals — supports gut health, metabolism, and water filtration.
Formulation Ready
Ultra-low moisture content and customizable particle sizes for seamless mixing.
