Anionic, water-soluble cellulose derivative engineered for thickening, stabilization, binding, suspension control, water management, texture improvement, and anti-redeposition performance across food-grade, detergent-grade, ceramic-grade, oilfield-grade, and industrial applications.
LANDERCOLL CMC (Carboxymethyl Cellulose / Sodium Carboxymethyl Cellulose, CAS 9004-32-4) is a versatile, water-soluble cellulose derivative designed for manufacturers who need reliable thickening, stabilization, binding, suspension control, water management, texture improvement, and formulation consistency across a wide range of regulated and industrial applications.
Suitable food-grade CMC is recognized as food additive E466 (also known as cellulose gum) and is used in sauces, beverages, bakery systems, frozen foods, and dairy-related products. In detergent systems, CMC provides anti-redeposition performance and soil suspension. In ceramics, it delivers binding, plasticity, and green strength. In oilfield fluids, it supports viscosity control and filtration reduction. Across paper, textile, pharmaceutical, and industrial systems, it provides reliable thickening, binding, and stabilization.
LANDERCOLL CMC is a versatile carboxymethyl cellulose product designed for manufacturers who need reliable thickening, stabilization, binding, suspension control, water management, texture improvement, and formulation consistency across a broad range of industries and application systems.
As a water-soluble, anionic cellulose derivative, CMC is especially valuable in food and nutrition systems, detergents and home care, toothpaste and personal care, pharmaceuticals, ceramics, oilfield fluids, paper and pulp, textile printing, adhesives, and other industrial formulations. It is particularly well-suited for applications where viscosity, structure, particle suspension, anti-redeposition, water binding, or texture stability are important performance requirements.
Different industries require different CMC grades. The right selection depends on viscosity level, degree of substitution, purity specification, dissolution behavior, salt tolerance, pH environment, regulatory requirements, and final product performance target. LANDERCOLL supports customers with application-based product selection, grade matching, and practical technical communication.
CMC stands for Carboxymethyl Cellulose. In commercial and industrial applications, it is most commonly supplied as Sodium Carboxymethyl Cellulose (Na-CMC) — a water-soluble, anionic cellulose derivative produced by introducing carboxymethyl groups (–CH₂COONa) onto the cellulose backbone. Its CAS number is 9004-32-4.
In food-related applications, CMC is commonly referred to as cellulose gum and is listed as food additive E466 in the EU food additive database under the name sodium carboxymethyl cellulose / cellulose gum. Food use requires the correct compliant grade and adherence to the regulations of the target market.
CMC is produced by reacting purified natural cellulose — typically derived from wood pulp or cotton linter — with sodium monochloroacetate under controlled alkaline conditions. This reaction introduces carboxymethyl groups onto the cellulose backbone, converting the insoluble natural polymer into a water-soluble, anionic polyelectrolyte.
Average number of carboxymethyl groups per glucose unit, typically ranging from 0.4 to 1.5. Higher DS generally improves water solubility, salt tolerance, and clarity of solution. DS directly affects performance in food, oilfield, and industrial applications.
Measured at 1% or 2% aqueous solution, ranging from very low (below 50 mPa·s) to very high viscosity (above 10,000 mPa·s), depending on molecular weight and concentration.
The sodium chloride and sodium glycolate content varies by grade. High-purity grades (typically >99% active content) are required for food, pharmaceutical, and personal care applications. Technical grades are used in ceramics, oilfield, paper, textile, and industrial systems.
Unlike HPMC, HEMC/MHEC, and HEC — which are non-ionic — CMC is an anionic cellulose derivative carrying a negative charge in solution. It is sensitive to multivalent cations (Ca²⁺, Mg²⁺, Al³⁺) and high salt concentrations, which can reduce its viscosity and solubility. It provides anti-redeposition performance in detergent systems through electrostatic interaction with fabric surfaces, and can interact with positively charged ingredients in formulations.
CMC is generally more cost-effective than non-ionic cellulose ethers for many industrial applications. Understanding CMC's anionic nature is critical for formulation compatibility assessment, particularly in high-electrolyte systems.

One of the most important functions of CMC in laundry detergent systems. CMC adsorbs onto fabric surfaces — particularly cotton and cellulosic fibers — creating a protective barrier that repels soil particles through electrostatic and steric effects, keeping removed soil suspended in wash water rather than redepositing on clean fabric.
In food, toothpaste, personal care, and household products, CMC helps create a smoother, more stable, and more controlled product texture — contributing to pleasant mouthfeel in food systems, smooth extrusion behavior in toothpaste, and consistent sensory feel in personal care products.
CMC grade selection should always begin with the target application and required compliance level. A CMC grade used in detergents may not be suitable for food or pharmaceutical applications, and a food-grade CMC may not be optimized for ceramic or oilfield performance. The table below provides a structured reference for common application-to-grade matching.

Provides thickening, suspension of particulates, mouthfeel improvement, and storage stability. Maintains uniform product consistency and prevents phase separation.
Retains moisture, improves crumb texture, extends shelf life, and reduces ice crystal formation in frozen systems for better freeze-thaw stability.
Low to medium viscosity food-grade CMC stabilizes suspensions, improves mouthfeel, and maintains uniform product appearance in fruit juices, plant-based drinks, and flavored beverages.
Controls ice crystal growth, improves body and texture, and maintains product quality during storage and temperature fluctuation. Supports protein stabilization in dairy-related systems.
CMC is an important functional additive in detergent formulations, particularly laundry detergent systems. Its primary role is anti-redeposition — preventing soil and dirt particles that have been removed from fabrics from redepositing onto fabric surfaces during the wash cycle.
CMC achieves anti-redeposition by adsorbing onto fabric surfaces — particularly cotton and cellulosic fibers — creating a protective barrier that repels soil particles through electrostatic and steric effects. CMC has been used for this purpose in laundry detergent formulations for decades and remains one of the most cost-effective anti-redeposition agents available.

Farmaceutisch
Suitable pharmaceutical grades of CMC may be used as a binder, suspending agent, stabilizer, viscosity modifier, or disintegration-related ingredient. CMC is referenced in major pharmacopoeias including USP/NF and Ph. Eur. under the monograph name Carmellose Sodium.
Keramiek
CMC is used as a binder, plasticizer, suspension stabilizer, and process aid across multiple ceramic manufacturing stages. It is one of the most widely used organic additives in the ceramics industry due to its effectiveness at low dosage and its ability to burn out cleanly during firing.
Olieveld
CMC is widely used in oilfield fluid systems where viscosity control, filtration reduction, suspension performance, and mud stability are required. In drilling fluid applications, CMC builds and maintains fluid viscosity to support drill cuttings transport, and reduces filtration loss by forming a thin, low-permeability filter cake on the wellbore wall.

Water-based paints · Coatings · Personal care · Detergents · OilfieldCMC (E466 / Carmellose Sodium) is the established standard for food stabilization, texture, anti-redeposition in laundry detergents, and toothpaste binding. Generally more cost-effective than HPMC for these applications. CMC's anionic nature provides the electrostatic interaction with fabric surfaces that drives anti-redeposition performance.
CMC is the most commonly used cellulose derivative in ceramics and oilfield applications due to its cost-effectiveness, reliable performance at suitable technical grades, and availability in grades matched to each industry's requirements. Clean burnout in ceramics and reliable fluid-loss control in oilfield systems.
For drymix construction materials, HPMC and HEMC/MHEC are more commonly selected due to stronger water retention in cement and gypsum systems. For water-based paints and latex coatings, HEC is preferred due to its strong latex compatibility and absence of thermal gelation.
LANDERCOLL CMC is supplied in industrial packaging suitable for transportation, storage, and production handling. CMC powder is hygroscopic and will absorb moisture from the environment if packaging is left open or storage conditions are inadequate. Proper storage conditions help maintain powder flowability, dissolution behavior, viscosity performance, and product stability throughout the shelf life.
