Used as a disintegrant in oral pharmaceutical formulations to help tablets break apart quickly in the gastrointestinal tract, ensuring rapid release and absorption of the active ingredient. It absorbs water and swells, promoting tablet dissolution even under compression. Commonly found in immediate-release tablets and capsules where fast onset of action is desired. Also used in some cases to stabilize emulsions or as a suspending agent in liquid dosage forms. Its high swelling capacity makes it effective in low concentrations, improving manufacturing efficiency and product performance.
