Introduction

CMC Powder (Carboxymethyl Cellulose), also known as Sodium Carboxymethyl Cellulose, is a premium-quality water-soluble cellulose derivative widely used as a thickener, stabilizer, binder, suspending agent, film former, water-retention agent, and rheology modifier across numerous industries. Due to its outstanding viscosity control, excellent water solubility, and superior stabilization properties, CMC has become one of the most important functional additives in modern industrial manufacturing.

Manufactured from high-purity natural cellulose through a controlled chemical modification process, CMC Powder offers consistent quality, excellent dispersibility, and reliable performance in both aqueous and industrial formulations. Its ability to improve texture, control viscosity, prevent sedimentation, and retain moisture makes it an essential ingredient in food products, drilling fluids, detergents, pharmaceuticals, ceramics, paints, textiles, paper manufacturing, cosmetics, and construction chemicals.

Whether used in high-performance drilling fluids or premium food formulations, CMC Powder delivers dependable performance and contributes significantly to product quality and process efficiency.

Product Overview

CMC Powder is supplied as a white to off-white, odorless, free-flowing powder that dissolves readily in cold or warm water to form a clear or slightly hazy viscous solution. The viscosity can be selected according to the required application, making CMC suitable for a wide variety of industrial processes.

Its excellent compatibility with numerous additives and raw materials allows manufacturers to formulate products with improved stability, consistency, and shelf life.
