Cellozize Tylose

Whatsapp Order

Cellozize Tylose, commonly known by the trade name Tylose, is a brand of hydroxyethyl cellulose (HEC), a non-ionic, water-soluble cellulose ether derived from natural cellulose. It appears as a white to off-white powder with excellent thickening, binding, and film-forming properties. Tylose is widely used as a rheology modifier, stabilizer, and thickener in various industries including construction, pharmaceuticals, cosmetics, and food. It provides viscosity control, improves texture, and enhances water retention in formulations. Due to its inert, non-toxic, and biodegradable nature, Tylose is favored as a versatile polymer in many applications.
