Sodium Carboxymethyl Cellulose (CMC) is a derivative of cellulose, the most abundant organic polymer found in the cell walls of plants. It is produced by chemically reacting cellulose (usually from wood pulp or cotton lint) with chloroacetic acid in an alkaline medium. The result is a water-soluble anionic polymer with the chemical formula [C₆H₇O₂(OH)₂OCH₂COONa]ₙ.
Key Properties:
Water Solubility: Forms clear or slightly hazy, viscous solutions.
Thickener: Even at low concentrations, it significantly increases the viscosity of liquids.
Stabilizer: Prevents the separation of ingredients in emulsions and suspensions.
Film Former: Creates flexible, water-soluble films.
Non-toxic & Odorless: Generally recognized as safe for use in food and pharmaceuticals.
pH Tolerant: Stable over a wide pH range, though most effective in neutral to slightly alkaline conditions.
Major Uses and Applications
CMC's unique properties make it an incredibly versatile additive across numerous industries. It is often labeled as E466 in food products or simply as "cellulose gum."
1. Food Industry (Primary use as E466)
Thickening Agent: In sauces, gravies, pie fillings, and icings.
Stabilizer and Emulsifier: Prevents ice crystal formation in ice cream, improves texture in yogurt, and stabilizes beer foam.
Moisture Retention: Keeps baked goods like cakes and tortillas soft and fresh for longer.
Binder: Holds together processed meats (e.g., chicken nuggets, sausages) and vegetarian patties.
Fat Replacer: Mimics the mouthfeel of fat in low-calorie products.
2. Pharmaceutical & Personal Care
Tablet Binder & Disintegrant: Binds powders into tablets and helps them break apart in the digestive system.
Lubricant: In eye drops and artificial tears.
Thickener in Toothpaste: Provides the desired gel-like consistency.
Suspending Agent: In liquid medications and antacids.
Emulsifier in Lotions/Creams: Stabilizes oil-and-water mixtures.
3. Industrial & Technical Applications
Detergent Additive: Acts as a soil-suspending and anti-redeposition agent in laundry detergents (prevents dirt from re-settling on clothes).
Paper & Textile Sizing: Adds strength, smoothness, and improves ink/grease resistance.
Drilling Fluid Additive: Controls fluid loss and viscosity in oil and gas well drilling mud.
Ceramics: Binds components in ceramic glazes and bodies.
Adhesives & Paints: Thickener and stabilizer.
4. Other Niche Uses
Artist's Gesso: Used as a binder and thickener.
Slime Toys: Provides the viscous, non-Newtonian fluid properties.
Tobacco Industry: Binder in reconstituted tobacco sheets.
Animal Feed: Pellet binder to improve durability.
