Description

Hydroxypropyl Methyl Cellulose CAS NO 9004-65-3 is a non-ionic, water-soluble cellulose ether derived from natural polymer cellulose. This versatile compound is prized for its excellent thickening, film-forming, water retention, and surface activity properties. It is an essential functional additive across numerous industries, including pharmaceuticals, construction, food, and personal care, where it acts as a binder, stabilizer, and rheology modifier.

Application

• Pharmaceuticals: Used as a binder, film-coating agent, and controlled-release matrix in tablet formulations.
• Construction Materials: Acts as a water-retention agent, thickener, and workability aid in cement-based tile adhesives, renders, and plasters.
• Food Industry: Functions as a thickener, emulsifier, and stabilizer in sauces, dairy products, and gluten-free baked goods.
• Personal Care & Cosmetics: Serves as a viscosity modifier, film former, and suspending agent in shampoos, lotions, and toothpastes.
• Paints & Coatings: Employed as a thickener and rheology modifier to improve application properties and sag resistance.
• Ceramics: Used as a binder and plasticizer in the production of ceramic bodies and glazes.

Quality Control

Our Hydroxypropyl Methyl Cellulose is manufactured under a strict quality management system. We offer various grades compliant with major pharmacopoeial standards, including USP-NF, EP, and JP, as well as Food Chemical Codex (FCC) specifications for food applications. Every batch undergoes rigorous testing for parameters such as viscosity, methoxy and hydroxypropoxy content, pH, and loss on drying. A Certificate of Analysis (COA) is provided with each shipment to ensure traceability and compliance.

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 degradation due to moisture absorption.
