Description

Methyl Ethylcellulose CAS NO 9004-59-5 is a non-ionic, water-soluble cellulose ether derivative, valued for its unique combination of film-forming, thickening, and stabilizing properties. This versatile polymer is essential for formulators requiring precise control over rheology, moisture retention, and binding characteristics in aqueous systems. It is a critical component for industries such as pharmaceuticals, construction, personal care, and food technology, where consistent performance and regulatory compliance are paramount.

Application

• Pharmaceuticals: Used as a binder, film-coating agent, and controlled-release matrix in tablet formulations.
• Construction Materials: Acts as a thickener, water-retention agent, and workability aid in cement-based tile adhesives, grouts, and renders.
• Personal Care & Cosmetics: Functions as a viscosity modifier, emulsion stabilizer, and film-former in creams, lotions, and hair care products.
• Food Industry: Employed as a thickener, stabilizer, and foam enhancer in various food products (where compliant with relevant food-grade standards).
• Paints & Coatings: Serves as a rheology modifier and protective colloid in water-based paints and polymer dispersions.
• Ceramics: Used as a binder and plasticizer in the shaping and production of ceramic bodies.

Quality Control

Our Methyl Ethylcellulose is manufactured under a strict quality management system. Each batch is tested against rigorous in-house specifications to ensure consistency in viscosity, degree of substitution, moisture content, and purity. We support compliance with relevant industry standards, and 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 initial opening to prevent moisture absorption and caking.
