Description

Chitosan is a linear polysaccharide derived from the deacetylation of chitin, a natural polymer found in crustacean shells. This versatile biopolymer is valued for its biocompatibility, biodegradability, and unique cationic properties, making it a critical functional material across diverse industries. Key industrial users include manufacturers in the pharmaceutical, nutraceutical, cosmetic, water treatment, and agricultural sectors seeking natural and effective solutions for formulation, purification, and delivery applications.

Application

• Pharmaceutical & Medical: Used as an excipient in controlled drug delivery systems, a wound healing agent in hemostatic dressings, and a component in tissue engineering scaffolds.
• Nutraceutical & Dietary Supplements: Employed as a dietary fiber for weight management supplements due to its fat-binding properties.
• Cosmetics & Personal Care: Functions as a natural film-forming agent, moisturizer, and antimicrobial ingredient in creams, lotions, and hair care products.
• Water & Waste Treatment: Acts as a highly effective natural flocculant and chelating agent for the removal of heavy metals, dyes, and suspended solids in industrial effluent.
• Agriculture & Horticulture: Serves as a bio-stimulant and elicitor to enhance plant growth, boost natural defense mechanisms, and as a coating for seeds and fertilizers.
• Food Industry: Utilized as a natural preservative edible coating to extend the shelf life of fruits and vegetables, and as a clarifying agent in beverages.

Quality Control

Our Chitosan is produced under strict quality management systems to ensure batch-to-batch consistency and reliability. Quality parameters such as degree of deacetylation (DDA), viscosity, molecular weight distribution, and impurity profiles are rigorously controlled. Certificates of Analysis (COA) detailing specifications and test results are provided with every shipment. We can supply grades compliant with various standards, including Food Chemical Codex (FCC) and pharmaceutical monographs, upon request.

Storage

Preserve in a tightly closed container, protected from light. This product is hygroscopic (moisture-sensitive) and must be stored in a cool, dry place at controlled room temperature (15-25°C). Ensure the original container is kept sealed when not in use to prevent moisture absorption, which can affect physical properties and performance.
