Description
Products Description
Chitosan is a natural polysaccharide derived from chitin - most commonly sourced from crustacean shells (shrimp or crab) - through a deacetylation process. Its functional properties vary significantly with molecular weight: low molecular weight chitosan offers higher solubility and lower viscosity, well suited to pharmaceutical and drug-delivery applications, while high molecular weight chitosan forms stronger films and gels, making it more suitable for water treatment, coatings, and certain cosmetic applications. Because different applications call for different molecular weight ranges, we supply chitosan across the full spectrum rather than a single fixed grade.
Sheerherb's Chitosan Powder is available in low, medium, and high molecular weight grades, with degree of deacetylation and viscosity verified on every batch. We supply supplement manufacturers, cosmetic formulators, and industrial buyers sourcing chitosan raw material matched to their specific molecular weight and viscosity requirements.

Product Benefits
Chitosan Powder is valued mainly for its molecular weight-dependent versatility, which underpins its use across multiple product categories:
1. Weight Management Formulations
Chitosan is widely used in "fat-binder" style weight-management supplements, based on its ability to bind dietary fats in the digestive tract - one of its most established commercial applications.
2. Film-Forming & Cosmetic Applications
Higher molecular weight grades support film-forming and moisturizing properties in cosmetic and personal care formulations.
3. Antimicrobial & Food Preservation Positioning
Its natural antimicrobial activity supports use in food preservation coatings and shelf-life extension applications.
4. Pharmaceutical & Drug-Delivery Applications
Lower molecular weight grades, with better solubility, are used in pharmaceutical formulation and controlled-release drug-delivery systems.
Products Application
Dietary Supplements (Weight Management)
Medium-to-high molecular weight grades support capsule and tablet formulations targeting fat-binding and weight-management claims.
Cosmetics & Personal Care
High molecular weight, film-forming grades support inclusion in moisturizers, hair-care products, and skin-conditioning formulations.
Industrial & Water Treatment Applications
High molecular weight chitosan's flocculating properties support use in water treatment and wastewater purification processes.
FAQ
Q: What molecular weight grades do you offer for bulk orders?
A: Low (50,000–190,000 Da), medium, and high (1,000,000+ Da) molecular weight grades, with customizable degree of deacetylation. Specs can be adjusted to your application, with COA, MSDS, and microbiological reports provided per batch.
Q: What is your MOQ for wholesale orders?
A: MOQ typically starts from 1kg for trial quantities, up to 25kg drums for commercial orders. Flexible terms available for long-term partnerships.
Q: Is this product allergen-safe?
A: Chitosan is derived from crustacean shellfish (shrimp/crab shell), so it is not suitable for shellfish-allergic consumers and should be labeled accordingly.
Q: How do you ensure quality and stability during shipping?
A: Controlled deacetylation process, packed in moisture-resistant, food-grade packaging. Recommend storing in a cool, dry place away from direct light.
Q: How do you ensure batch-to-batch consistency?
A: Every batch is tested for molecular weight (viscosity), degree of deacetylation, and microbial limits before release, with full documentation provided for traceability.
