Villosol is primarily used in pharmaceutical and biotechnological applications due to its surfactant and solubilizing properties. It is commonly employed in drug delivery systems to enhance the bioavailability of poorly water-soluble drugs. Its ability to stabilize emulsions and form micelles makes it valuable in formulating injectable and oral dosage forms. Additionally, Villosol finds use in laboratory settings as a cell membrane disruptor in protein extraction and cellular lysis protocols. It is also utilized in cosmetic formulations for its emulsifying and skin-conditioning effects, helping to improve product texture and absorption.
