Description

Cellulose CAS NO 9012-19-5 is a naturally occurring linear polysaccharide polymer composed of β(1→4) linked D-glucose units, serving as the primary structural component of plant cell walls. This versatile biopolymer is valued for its excellent mechanical strength, biodegradability, and chemical modification potential, making it a cornerstone material across numerous industries. It is essential for manufacturers in the pharmaceutical, food, construction, textile, and personal care sectors seeking sustainable and high-performance raw materials.

Application

• Pharmaceutical Excipients: Used as a binder, disintegrant, and controlled-release matrix in tablet and capsule formulations.
• Food Industry: Acts as a thickener, stabilizer, and dietary fiber (microcrystalline cellulose) in various food products.
• Construction Materials: Serves as a rheology modifier and water retention agent in cement-based products like tile adhesives and joint compounds.
• Paper & Packaging: The fundamental raw material for producing paper, cardboard, and other cellulose-based packaging.
• Textile Manufacturing: Used to produce regenerated cellulose fibers such as viscose rayon and lyocell.
• Personal Care & Cosmetics: Functions as a viscosity controller, emulsion stabilizer, and abrasive in products like creams, lotions, and toothpaste.
• Chemical Synthesis: A key feedstock for producing cellulose derivatives like cellulose acetate, carboxymethyl cellulose (CMC), and ethyl cellulose.
• Filtration & Separation: Employed in the form of filter aids and chromatographic media for industrial purification processes.

Quality Control

Our cellulose products are manufactured and tested under a strict quality management system to ensure batch-to-batch consistency and compliance with relevant pharmacopeial and industrial standards. We provide comprehensive Certificates of Analysis (COA) for each batch, detailing key parameters such as degree of polymerization, moisture content, and purity. Depending on the grade, our products can meet specifications for USP-NF, Ph. Eur., FCC, and other international standards.

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 flow properties and performance.
