The effect is an enormous increase of the swelling of the middle phase microemulsion by water and oil. The magnitude of the effect depends slightly but systematically on the chain length of the surfactant forming the base system and on the chain length of thealkane. Interestingly, the less efficient the base system the larger the boosting effect. Furthermore, the lamellar phase, which usually develops as surfactants become more efficient, is suppressed, the more the less efficient the surfactant of the base system.
