Interface Technology

An interface is the boundary between any two of the three phases of matter (solid, liquid or gas); the study of such interfaces is interface science. For more than 100 years, Lion has been involved in interface science research, producing cutting-edge detergents and other products. In recent years, Lion has developed surfactants made from plant-derived palm oil, aiming to provide more environment-friendly products. The excellent detergency and biodegradability of these surfactants have garnered widespread attention. In addition, we employ world-leading technologies to study various interfacial mechanisms, such as those that produce foam, an interface phenomenon of air and liquid, and emulsions, an interface phenomenon of oil and water. By steadily advancing such research, we are expanding our focus from surfactants to include other areas as we work to develop the cleaning technologies of the future.
