Description

Cellulose, Phosphate Sodium Salt is a chemically modified cellulose derivative where phosphate groups are introduced onto the cellulose backbone, imparting unique anionic and hydrophilic properties. This modification is critical for enhancing functionality in applications requiring controlled viscosity, thickening, and stabilization. It serves as a key ingredient for formulators and manufacturers in the pharmaceutical, food, and personal care industries seeking reliable, high-performance excipients and additives.

Application

• Pharmaceutical Excipient: Used as a disintegrant, binder, and controlled-release matrix former in tablet and capsule formulations.
• Food Industry Additive: Functions as a thickener, stabilizer, and emulsifier in various food products, often where specific ionic interactions are required.
• Personal Care & Cosmetics: Employed in creams, lotions, and gels to modify rheology, stabilize emulsions, and provide a smooth texture.
• Industrial Applications: Acts as a water-retention agent, thickener, or suspending aid in ceramic glazes, adhesives, and other specialty formulations.
• Biomedical Research: Utilized in chromatography media and as a substrate for studying enzyme interactions due to its modified polysaccharide structure.

Quality Control

Our Cellulose, Phosphate Sodium Salt is manufactured under a strict quality management system. Each batch is tested to ensure it meets consistent specifications for identity, purity, and performance. While available in various grades, our standard product is suitable for industrial and technical applications, with higher purity grades available upon request. A Certificate of Analysis (COA) documenting key parameters is provided with every shipment.

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); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can affect product performance.
