KimaCell Sodium Carboxymethyl Cellulose

Sodium Carboxymethyl Cellulose (CMC), often referred to as cellulose gum, is one of the most versatile water-soluble polymers used across various industries. KimaCell Sodium CMC is a high-quality, refined form of this polymer, produced through advanced manufacturing processes that ensure consistent performance, safety, and versatility. As a derivative of natural cellulose, CMC offers a unique balance of thickening, stabilizing, binding, and film-forming properties, making it an essential ingredient in food, pharmaceuticals, cosmetics, textiles, paper, oil drilling, and construction.

What is KimaCell Sodium Carboxymethyl Cellulose?

Sodium Carboxymethyl Cellulose is derived from cellulose, the most abundant natural polymer found in the cell walls of plants. Through a chemical modification process, cellulose reacts with sodium monochloroacetate in an alkaline medium to form the sodium salt of carboxymethyl cellulose. This reaction introduces carboxymethyl groups (-CH2-COONa) into the cellulose backbone, making the polymer water-soluble and giving it unique functional properties.

KimaCell is manufactured with stringent quality control measures to achieve specific degrees of substitution (DS), viscosity levels, and purity grades, making it suitable for applications that demand consistent performance. Its biocompatibility and biodegradability make it a sustainable and environmentally friendly material.

Key Properties of KimaCell Sodium CMC

KimaCell CMC exhibits several distinctive physical and chemical properties that account for its widespread use:

Water Solubility: KimaCell dissolves quickly in cold or hot water, forming a clear, viscous solution.

Thickening Agent: Even at low concentrations, it significantly increases viscosity, allowing for better control of fluid texture and flow.

Stabilizing Action: It prevents phase separation in emulsions and suspensions by providing a stable matrix.

Film-Forming Capability: When dried, CMC forms a flexible, transparent film, useful in coatings and protective layers.

Non-Toxic and Biodegradable: Derived from natural cellulose, it is safe for food, pharmaceutical, and personal care applications.

pH Stability: Performs effectively in a wide pH range, typically between 4 and 10.

Electrolyte Sensitivity: Exhibits tolerance to certain salts, allowing for usage in challenging formulations such as detergents and oil drilling fluids.

These properties can be tailored by adjusting molecular weight, degree of substitution, and particle size, enabling KimaCell to meet the requirements of diverse applications.

Production Process of KimaCell CMC

The manufacturing process of KimaCell Sodium CMC involves several carefully controlled steps:

Alkalization: Purified cellulose is treated with sodium hydroxide to form alkali cellulose.

Etherification: Alkali cellulose reacts with sodium monochloroacetate, resulting in carboxymethyl substitution on the cellulose chain.

Purification: By-products such as sodium chloride and sodium glycolate are removed to enhance purity.

Drying and Milling: The purified CMC is dried, milled, and sieved to obtain specific particle sizes and uniform quality.

Quality Control: Final product is tested for degree of substitution, viscosity, purity, and microbiological safety.

KimaCell's process ensures a product with low salt content, consistent viscosity, and high stability, meeting international quality standards.
