metüültselluloosi

Metüültselluloos, often abbreviated as MC, is a non-ionic, water-soluble polymer derived from cellulose. It is produced by the chemical modification of cellulose through etherification with methyl groups. This process alters the properties of cellulose, making it soluble in water and providing it with a range of useful characteristics. Metüültselluloos is a white to off-white fibrous or granular powder.

One of the primary applications of metüültselluloos is as a thickener, binder, and stabilizer in various industries. In the food industry, it is used as a food additive (E number E461) to improve texture, increase viscosity, and provide emulsion stability. It can be found in products like ice cream, sauces, and baked goods. In pharmaceuticals, it serves as a binder in tablet formulations, a viscosity modifier in liquid medications, and a component of controlled-release drug delivery systems.

Metüültselluloos also finds significant use in the construction industry, particularly as an additive in dry-mix mortars, tile adhesives, and plasters. It enhances workability, improves water retention, and increases adhesion. Its ability to retain water is crucial for cementitious materials, preventing premature drying and ensuring proper curing. Other applications include its use in paints, cosmetics, and as a component in some packaging materials. Metüültselluloos is generally considered safe and biodegradable.
