Description

Chitin is a long-chain biopolymer of N-acetylglucosamine, a naturally occurring structural polysaccharide found in the exoskeletons of arthropods and the cell walls of fungi. Its unique biocompatibility, biodegradability, and non-toxic nature make it a critical raw material for advanced, sustainable industrial and biomedical applications. This high-purity product is essential for manufacturers and R&D teams in the pharmaceutical, cosmetic, agricultural, and food technology sectors seeking reliable, high-quality biopolymer sources.

Application

• Pharmaceutical & Biomedical: As a precursor for chitosan production, used in wound healing dressings, drug delivery systems, and tissue engineering scaffolds.
• Cosmetics & Personal Care: Utilized as a film-forming agent, thickener, and moisturizer in creams, lotions, and hair care products for its skin-adhesive and protective properties.
• Agriculture & Horticulture: Employed in seed coatings, fertilizers, and soil conditioners to enhance plant growth and provide natural antifungal protection.
• Food & Beverage: Acts as a natural food preservative, dietary fiber supplement, and clarifying agent in juice and wine processing.
• Water Treatment: Serves as a bio-adsorbent for the removal of heavy metals, dyes, and other pollutants from industrial wastewater.
• Biotechnology: Used as a support matrix for enzyme immobilization and chromatographic separation processes.

Quality Control

Our Chitin is produced under stringent quality management protocols to ensure batch-to-batch consistency and high performance. We offer various grades, including technical, food, and pharmaceutical grades, with specifications tailored to your application. A comprehensive Certificate of Analysis (COA) detailing purity, viscosity, ash content, and particle size is provided with each shipment to guarantee compliance with your requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect the product's physical properties and stability.
