Emulsions are essential in our modern daily life. The influences and applications of different kinds of emulsions reach pharmaceutical,¹  petroleum,²  biocatalysis^3,4  and food industries.^5,6  An emulsion is a heterogeneous system which consists of a dispersed liquid in another liquid as a continuous phase.⁷  However, the mixing of two or more liquids which have very different polarity is obviously not favourable. As a result, these thermodynamically unstable systems undergo separation in the matter of seconds.

Therefore, one might use surfactants to kinetically stabilize them, slowing the coalescence process of the dispersed droplets and phase separation.^8...
