Description

Cellulose, Hydroxymethyl Ether CAS NO 37353-59-6 is a chemically modified cellulose derivative, also known as hydroxymethyl cellulose (HMC). This compound is valued for its ability to modify rheology, stabilize emulsions, and act as a thickener or binder in aqueous systems. It serves as a critical functional additive for formulators and manufacturers across the pharmaceutical, food, and personal care industries seeking reliable, water-soluble polymer performance.

Application

• Pharmaceutical Formulations: Used as a binder, film-coating agent, and controlled-release matrix in tablet and capsule manufacturing.
• Food & Beverage Industry: Functions as a thickener, stabilizer, and emulsifier in sauces, dairy products, and gluten-free baked goods.
• Personal Care & Cosmetics: Acts as a viscosity modifier and suspension agent in lotions, creams, shampoos, and toothpastes.
• Construction Materials: Employed as a water retention agent and workability aid in cement-based products like tile adhesives and joint compounds.
• Paints & Coatings: Serves as a rheology modifier to improve application properties and prevent sagging in water-based paints.
• Detergents & Household Cleaners: Used to stabilize foam and suspend soil particles in liquid detergent formulations.
• Textile Printing & Sizing: Acts as a thickener for dye pastes and a protective coating for yarns.
• Ceramics & Adhesives: Functions as a temporary binder and processing aid in various industrial applications.

Quality Control

Our Cellulose, Hydroxymethyl Ether is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for viscosity, degree of substitution, purity, and moisture content. Certificates of Analysis (COA) are provided and the product can be supplied to meet various standards, including Food Grade (FCC) and Pharmaceutical Grade 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 container must be kept tightly sealed after opening to prevent caking and degradation due to moisture absorption.
