tylose

Tylose is a brand name used for a family of cellulose ether polymers that act as thickening, stabilizing, binding, and gelling agents. The Tylose line includes derivatives such as methylcellulose, hydroxyethylcellulose, hydroxypropylcellulose, and hydroxypropyl methylcellulose (HPMC), produced under license by manufacturers associated with the Tylose name. These cellulose ethers are derived from cellulose, a natural polymer obtained from wood pulp or cotton linters, and are formed by etherification of the cellulose backbone.

These polymers are highly hydrophilic and form viscous, sometimes gel-like solutions when dispersed in water. They are non-ionic and relatively tolerant of wide pH ranges and varying salt contents, which makes them versatile across formulations. Depending on the derivative and grade, some Tylose products exhibit gelation upon heating (notably methylcellulose), while others provide stable, shear-thinning viscosity without gelling at room temperature.

Applications and usage span several industries. In foods and beverages, Tylose derivatives serve as thickeners and stabilizers. In cosmetics and personal care, they act as thickeners, suspending agents, and texture enhancers. In pharmaceuticals, they are used as binders, disintegrants, and suspending agents in formulations. In paints, coatings, and inks, they function as rheology modifiers to control flow and stability. In construction, certain Tylose grades are used as water-retention and thickening agents in cementitious mortars and plasters.

Safety and regulation: cellulose ethers are widely used and considered safe when used according to good manufacturing practices and regulatory guidelines. Regulatory status can vary by country and application, and proper handling is advised to minimize dust and exposure during processing.
