Description

Quaternary Chitosan (Black Soldier Fly – BSF)

Next-Generation, Shellfish-Free Quaternary Biopolymer for High-Performance Applications

Quaternary Chitosan (Soldier Fly) is a high-purity, next-generation chitosan derivative produced from Black Soldier Fly (BSF) chitosan through an advanced quaternization process. This modification delivers exceptional water solubility, strong antimicrobial activity, and superior bioavailability, while remaining shellfish-free and fully biodegradable.

Designed for cosmetic, pharmaceutical, medical, packaging, and industrial applications, this BSF-derived quaternary chitosan offers a cleaner, more sustainable alternative to traditional shellfish-based materials—without compromising performance.
