Description

Sodium Carboxymethylhydroxyethylcellulose is a high-performance, water-soluble cellulose ether derivative engineered for superior rheological control and stability. This multifunctional polymer is valued for its exceptional thickening, suspending, and water-retention properties across diverse industrial and consumer applications. Key industries that rely on this versatile additive include pharmaceuticals, personal care, construction, and food technology, where consistent quality and performance are paramount.

Application

• Pharmaceutical Formulations: Acts as a binder, disintegrant, and controlled-release matrix in tablet manufacturing, and as a viscosity modifier in topical gels and ophthalmic solutions.
• Personal Care & Cosmetics: Provides thickening, stabilizing, and film-forming properties in shampoos, lotions, creams, and toothpaste for enhanced texture and shelf-life.
• Construction Materials: Used as a water-retention agent and workability aid in cement-based products like tile adhesives, grouts, and self-leveling compounds.
• Food Industry: Functions as a thickener, stabilizer, and moisture-control agent in various food products, often where high clarity and purity are required.
• Paints & Coatings: Serves as a rheology modifier to prevent sagging and settling, improving the application properties and final finish of water-based paints.
• Detergents & Household Cleaners: Enhances viscosity and stabilizes formulations, contributing to the desired consistency and performance of liquid soaps and cleaning gels.

Quality Control

Our Sodium Carboxymethylhydroxyethylcellulose is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for viscosity, degree of substitution, purity, and pH. Certificates of Analysis (COA) are provided with every shipment, and we can support compliance with relevant standards such as USP-NF, FCC, or specific customer requirements upon request.

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 original container must be kept tightly sealed after use to prevent caking or degradation due to moisture absorption.
