Future Created by Surfactant-free Emulsions ～Switching to Emulsification in the Absence of Surfactants～

Abstract

Emulsion is a mixture of oil and water, which are immiscible with each other. So, in general, emulsifiers such as surfactants are required for the preparation of emulsions. On the other hand, it is concerned to be difficult to manufacture the emulsion products using surfactants due to the limitation of produced palm oil which is the raw material for surfactants, and the increasing global demand for surfactants. Therefore, the emulsification technique in the absence of any emulsifiers such as surfactants, which is named as surfactant-free emulsification, are strongly demanded. This paper reports the current situation and future possibilities of surfactant-free emulsions.
