E466 CMC

E466 CMC is a semi-synthetic polymer compound in white to cream-colored, odorless, fibrous powder or granular form at room temperature, obtained through the etherification of natural cellulose with monochloroacetic acid, used as a thickener, emulsifier, stabilizer, water retainer, and binder in food, pharmaceutical, cosmetic, detergent, and paper industries.
E466 CMC is an anionic cellulose ether raw material that dissolves easily in water to form clear and viscous solutions, known by the code E466 in food additive coding systems and commercially as Carboxymethyl Cellulose (CMC) or Cellulose Gum.
E466 CMC undertakes a critical role in preventing the growth of ice crystals in food products, providing suspension stability in beverages, fluid control in pharmaceutical syrups, and preventing the re-deposition of dirt in detergents.

E466 CMC is a functional component added to formulations in order to optimize the rheological properties of formulations, increase water-binding capacity, and establish a homogeneous colloidal structure that prevents phase separation during storage.
E466 CMC molecules provide high viscosity thanks to the carboxymethyl groups (-CH₂-COO⁻) attached to anhydroglucose units forming strong hydrogen bonds with water molecules and creating electrostatic repulsive forces to allow chain unwinding.
E466 CMC-containing food, pharmaceutical, and industrial products acquire excellent viscosity control, high water retention efficiency, smooth textural structure, and long shelf life performance.

E466 CMC is widely preferred at industrial standards, particularly as a texture enhancer in ice creams, a consistency regulator in sauces, and a flow behavior modifier in personal care products.
E466 CMC is a non-toxic, biocompatible, and reliable polymeric additive that maintains its chemical stability across wide pH ranges.
E466 CMC is produced at high purity standards and is one of the most sought-after cellulose derivatives in the global food, pharmaceutical, detergent, textile, and paper market.

WHAT IS E466 CMC?

E466 CMC is an anionic character cellulose ether compound known in the food and chemical industry under the names E466 CMC, Carboxymethylcellulose, Karboksimetil Selüloz, CMC, Cellulose Gum, or Sodium Carboxymethyl Cellulose.
E466 CMC is commercially presented to the market in white to cream-colored, odorless, tasteless, hygroscopic fibrous powder or granular form.
E466 CMC quality is determined according to specific control parameters such as purity degree, degree of substitution (DS), viscosity value, sodium chloride and sodium glycolate content, loss on drying, and heavy metal limits.
E466 CMC exhibits a unique physical behavior by dispersing homogeneously in cold and hot water to form clear viscous solutions while failing to dissolve in organic solvents.
E466 CMC also finds a wide usage area as a fluid loss control agent in drilling muds, a green strength enhancer in the ceramic industry, and a thickener in textile printing pastes.
E466 CMC amount and distribution uniformity of carboxymethyl groups in its molecular structure directly determine the water solubility and viscosity-building capacity of the polymer.

HOW DOES E466 CMC WORK AT THE MOLECULAR LEVEL?

E466 CMC ensures the formation of negative charges (carboxylate ions) on the polymer chain through the dissociation of sodium ions when dissolved in water.
E466 CMC molecules trigger the uncoiling and expansion of chains by the mutual repulsion of groups having the same charge, creating high viscosity and a network structure in solution.
E466 CMC presence restricts free water movement by tightly binding water molecules via hydrogen bonds and prevents the system from undergoing syneresis (water separation).
E466 CMC offers excellent suspension and emulsion stability under appropriate pH conditions, although its anionic structure allows it to interact with cationic components.

WHICH INDUSTRIES IS IT USED IN?

E466 CMC is used in the food industry as a consistency and texture regulator in ice creams, sauces, fruit juices, bakery products, dairy products, and diet foods.
E466 CMC takes place in pharmaceutical preparations as a tablet binder, suspending agent, eye drops, and in the production of topical gels.
