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.

CMC binds and manages water through its hydrophilic polymer network. This water-binding capability is important in food, bakery, and frozen food systems where moisture management and freeze-thaw stability are critical.
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.

Yes. In food-related applications, CMC is commonly referred to as cellulose gum. Suitable food-grade CMC is also known as sodium carboxymethyl cellulose and is listed as food additive E466 in the EU food additive system. The terms CMC, cellulose gum, and sodium carboxymethyl cellulose all refer to the same substance when used in food contexts.
Yes. Suitable food-grade CMC is approved as food additive E466 in the European Union and is recognized in food regulations in many other markets globally. Food use requires the correct compliant grade that meets applicable purity specifications and food safety standards. Compliance with the specific food regulations of the target market is required.
In laundry detergent, CMC primarily provides anti-redeposition performance — it prevents soil and dirt particles removed from fabrics during washing from redepositing back onto fabric surfaces. CMC adsorbs onto cotton and cellulosic fiber surfaces, creating a protective barrier that repels soil particles through electrostatic and steric effects. CMC also contributes to formulation stability and product consistency in both powder and liquid detergent systems.
In toothpaste, CMC provides binding, thickening, water retention, smooth extrusion behavior, stable paste structure, and uniform suspension of abrasive particles. It gives toothpaste its characteristic body and consistency, ensures smooth extrusion from the tube, and helps maintain stable product texture throughout the shelf life.
Yes. CMC is widely used in ceramic production as a binder, plasticity modifier, suspension stabilizer, and process aid. It improves the plasticity and workability of ceramic bodies during shaping, builds green strength before firing, stabilizes ceramic glaze suspensions, and burns out cleanly during the firing process without leaving residue.
Yes. CMC is used in water-based oilfield drilling fluids and completion fluids as a viscosity enhancer, filtration reducer, and mud stabilizer. It builds drilling fluid viscosity to support drill cuttings transport and reduces fluid loss into porous formations by forming a filter cake on the wellbore wall.
The most important difference is ionic type: CMC is anionic, while HPMC is non-ionic. CMC's anionic nature gives it anti-redeposition performance in detergents and sensitivity to multivalent cations and high salt concentrations. HPMC is non-ionic and more broadly compatible across different formulation environments. HPMC also exhibits thermal gelation, while CMC does not. CMC is more commonly used in food, detergents, ceramics, oilfield, and industrial systems; HPMC is more widely used in construction, pharmaceutical, and food film-forming applications.
Both CMC and HEC do not exhibit thermal gelation and remain soluble in cold and hot water. The key difference is ionic type: CMC is anionic, while HEC is non-ionic. CMC is more sensitive to salt and multivalent cations, but provides anti-redeposition performance in detergents. HEC is more compatible with latex polymer systems and preferred for water-based paints. CMC is generally more cost-effective and preferred in food, detergents, ceramics, and oilfield applications.
