Description

Oxycellulose is a chemically modified cellulose derivative, characterized by the introduction of carbonyl and carboxyl groups into the cellulose polymer chain. This modification imparts unique properties such as enhanced water solubility, biodegradability, and reactivity, making it a valuable functional biopolymer. It is a critical material for manufacturers in the pharmaceutical, biomedical, and specialty chemical industries seeking advanced, sustainable excipients and intermediates.

Application

• Pharmaceutical Excipient: Used as a disintegrant, binder, or controlled-release matrix in tablet formulations.
• Wound Care & Hemostats: Serves as a key component in absorbable hemostatic agents and wound dressings due to its biodegradability and ability to promote clotting.
• Chromatography Media: Employed as a base matrix for ion-exchange or affinity chromatography columns for protein purification.
• Biomedical Research: Utilized as a scaffold material in tissue engineering and for drug delivery system development.
• Specialty Chemical Synthesis: Acts as a reactive intermediate for the production of other cellulose esters and ethers with tailored properties.
• Food & Cosmetic Additive: Functions as a thickener, stabilizer, or dietary fiber supplement in specific high-value applications.

Quality Control

Our Oxycellulose is produced under a strict quality management system. Each batch is tested to ensure it meets precise specifications for carboxyl content, degree of oxidation, viscosity, and microbial limits. Certificates of Analysis (COA) documenting purity, identity, and performance characteristics are provided with every shipment. We can support compliance with relevant pharmacopeial standards (e.g., USP/NF) for applicable grades.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and must be kept in a low-humidity environment to prevent caking and degradation. Keep away from strong oxidizing agents.
