Hidroxietilcelulosa

Hidroxietilcelulosa, often abbreviated as HEC, is a non-ionic, water-soluble polymer derived from cellulose. It is produced by the etherification of cellulose with ethylene oxide. HEC is a white to off-white, odorless, and tasteless powder. It is highly soluble in water and can form viscous solutions. The degree of substitution, which refers to the number of hydroxyethyl groups attached to each anhydroglucose unit of the cellulose chain, influences its properties such as solubility and viscosity.

HEC is widely used as a thickener, binder, stabilizer, and suspending agent in various industries. In personal care products like shampoos, lotions, and cosmetics, it provides thickening and improves texture. In pharmaceuticals, it serves as a binder in tablets and a viscosity modifier in liquid formulations. The construction industry utilizes HEC in cementitious materials, mortars, and tile adhesives to improve workability, water retention, and adhesion. It is also found in paints and coatings as a rheology modifier, controlling flow and preventing sagging. HEC is known for its good compatibility with other ingredients and its resistance to microbial degradation. It is generally considered safe for its intended uses.
