Description

Methocel CAS NO 79484-92-7 is a high-quality, cellulose-based ether polymer widely recognized for its exceptional thickening, film-forming, and water-retention properties. This versatile excipient is crucial for achieving precise rheological control and stability in a wide range of industrial and pharmaceutical formulations. It is an essential material for formulators and manufacturers in the pharmaceutical, food, personal care, and construction industries seeking reliable performance and consistent quality.

Application

• Pharmaceuticals: As a binder, controlled-release matrix former, and viscosity modifier in tablet coatings, capsules, and topical gels.
• Food Industry: Used as a thickener, stabilizer, and emulsifier in sauces, dressings, bakery fillings, and low-fat products.
• Personal Care & Cosmetics: Functions as a film-former and rheology modifier in shampoos, creams, lotions, and toothpastes.
• Construction Materials: Acts as a water-retention agent and workability aid in cement-based products like tile adhesives, grouts, and renders.
• Paints & Coatings: Employed as a thickener and anti-sag agent to improve application properties and film integrity.
• Ceramics: Serves as a binder and plasticizer in the formation of ceramic bodies and glazes.

Quality Control

Our Methocel is manufactured under strict quality management systems to ensure batch-to-batch consistency and reliability. We offer grades that comply with major pharmacopoeial standards including USP-NF, EP, and JP, as well as food-grade specifications (FCC). Every lot is supported by a comprehensive Certificate of Analysis (COA) detailing key parameters such as methoxy and hydroxypropoxy content, viscosity, and moisture.

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 product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent caking or lump formation due to moisture absorption.
