Description

Cellulose, 2-Sulfoethyl Ether, Sodium Salt is a water-soluble, anionic cellulose derivative engineered for superior rheological control and ionic functionality. This compound matters for formulators seeking to enhance viscosity, stability, and performance in aqueous systems where traditional thickeners may fall short. Key industries that need this specialized polymer include pharmaceuticals for controlled-release matrices, personal care for advanced hair and skin care products, textiles as a dye-leveling and printing agent, and industrial applications such as water-based coatings and ceramic binders.

Application

• Pharmaceutical Excipient: Used as a binder, disintegrant, and controlled-release matrix former in tablet and capsule formulations.
• Personal Care & Cosmetics: Functions as a thickener, stabilizer, and film-forming agent in shampoos, conditioners, lotions, and gels.
• Textile Industry: Serves as a dye-leveling agent, thickener for printing pastes, and finishing agent to improve fabric hand feel.
• Water-Based Coatings & Adhesives: Acts as a rheology modifier and thickener to control application properties and prevent sagging.
• Ceramics & Building Materials: Employed as a binder and water retention agent in ceramic slips and construction mortars.
• Paper Manufacturing: Enhances strength, retention, and drainage as a wet-end additive and coating agent.
• Enhanced Oil Recovery (EOR): Investigated for use as a viscosifier in polymer flooding to improve oil displacement.

Quality Control

Our Cellulose, 2-Sulfoethyl Ether, Sodium Salt is manufactured under a strict quality management system. Each batch is tested to ensure it meets defined specifications for parameters such as degree of substitution, viscosity, purity, and moisture content. We can provide material compliant with relevant pharmaceutical (e.g., ICH Q7) and industrial standards. A comprehensive Certificate of Analysis (COA) documenting all test results is available for 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). Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product performance.
