Applications

1.Natural Cationic Biopolymer: Made by deacetylating chitin recovered from shrimp and crab shell waste, it is a linear polysaccharide whose free amino groups carry a natural positive charge, giving formulators cationic performance from a renewable material.

2.Water And Wastewater Treatment Flocculant: Used as a natural flocculant and adsorbent in industrial and municipal treatment, where its amino and hydroxyl groups bind lead, copper and chromium ions and gather suspended solids, dyes and colloids into flocs that settle or filter out.

3.Food Preservation And Edible Coatings: Cast from dilute acid solution, it forms clear oxygen-limiting and antimicrobial films on fruits, vegetables, meat and seafood, helping packers and exporters cut moisture loss and microbial spoilage during cold-chain transport and retail display.

4.Cosmetics And Personal Care: Its cationic backbone binds to negatively charged skin and hair, so it works as a film-forming, moisturizing and conditioning polymer in skin gels, serums, sheet masks, scalp tonics and hair care products, while stabilizing emulsions and suspensions.

5.Agriculture And Plant Defense: Applied as a seed coating, foliar spray or soil amendment, it triggers plant defense responses and supports germination, root development and tolerance to fungal pathogens, drought and salinity, fitting biocontrol and sustainable farming programs.
