Abstract:In industries, emulsions must adapt to various acid-base environments, making it crucial to study their properties and acid-base resistance. We prepared an oil-in-water (O/W) emulsion by adding oleic acid and polyether amine D-230 to water, with tetradecane as the oil phase. The stability of the emulsion was assessed by measuring the interaction forces between droplets using optical tweezers. Our results demonstrated that the amphoteric surfactant could significantly improve the stability of the emulsion. The … Show more
