With two GMP certified manufacturing lines and a team of 30 technical professionals, we provide pharmaceutical grade biopolymer solutions to over 60 countries. Our product undergoes strict quality control such as heavy metal detection, microbiological testing and viscosity analysis to assure batch to batch consistency for demanding applications.
What Is Chitosan Powder?
The outcome is a straight polysaccharide, alkaline N-deacetylated from chitin, typically from the bodies of crabs like shrimp and crab. This cationic biopolymer is biodegradable, biocompatible and mucoadhesive.
The white crystalline powder dissolves easily in dilute acid solutions (pH 4-6). Chitosan is positively charged, and so may interact electrostatically with negatively charged molecules. This is particularly significant for chelation, encapsulation and film production in nutraceutical and pharmaceutical businesses.

FAQ
Q: What is the main difference between food-grade and pharmaceutical-grade chitosan?
A: Pharmaceutical grade has a greater degree of deacetylation (≥90%), more stringent limitations on microbes, and verified amounts of endotoxin. Both requirements are met by our product.
Q: Does the item dissolve right away in water?
A: No, it needs a moderately acidic environment (pH 4-6) like a weak acetic acid or citric acid solution to dissolve all the way.
Q: How much of these weight control vitamins should I take?
A: Normal dose is 1000-3000mg a day, 30 minutes before food. Always find out what the rules are in your area.
Q: Does molecular weight have an impact on application performance?
A: Low MW (50-190 kDa) is preferred for beverage solubility; high MW (>300 kDa) gives greater film strength for coatings. We are here to meet your requirements.
Q: Do you have regulatory supporting documents?
A: Yes, we ship with COA, MSDS, allergy statements, BSE/TSE free certifications and non-GMO declarations.
