Hectorite is a natural smectite clay mineral widely used as a rheology modifier, thickener, suspension stabilizer, and gelling agent. It is commonly applied in cosmetics, personal care products, coatings, paints, inks, adhesives, drilling fluids, and specialty industrial formulations. Hectorite improves viscosity control, dispersion stability, and texture performance in liquid systems.
