Description

Chitosan Hydrochloride is a water-soluble derivative of chitosan, a natural biopolymer derived from chitin. This modification enhances its solubility in aqueous systems, making it a versatile functional ingredient for demanding applications. It is particularly valuable in the pharmaceutical, cosmetic, and biotechnology industries where biocompatibility and cationic functionality are required. The compound is supplied under strict quality control to ensure batch-to-batch consistency for industrial and research use.

Application

• Pharmaceutical Excipient: Used as a tablet binder, disintegrant, and for controlled drug delivery systems due to its mucoadhesive properties.
• Cosmetic Formulations: Acts as a conditioning agent, film-former, and viscosity modifier in hair care and skin care products.
• Biotechnology & Research: Employed in cell culture, enzyme immobilization, and as a transfection reagent in molecular biology.
• Dietary Supplement & Nutraceuticals: Utilized in formulations for weight management and cholesterol control supplements.
• Water Treatment: Functions as a natural flocculant for the removal of suspended solids and heavy metals in wastewater.
• Agriculture: Used in seed coatings and as an elicitor to enhance plant defense mechanisms and growth.

Quality Control

Our Chitosan Hydrochloride is manufactured under a quality management system. Each batch undergoes rigorous analytical testing to ensure it meets defined specifications for identity, purity, and performance. Certificates of Analysis (COA) documenting key parameters such as degree of deacetylation, viscosity, and heavy metal content are available upon request. We can support compliance requirements for various application standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the original container tightly sealed to prevent absorption of atmospheric moisture.
