Miniemulsion
A miniemulsion (also known as a nanoemulsion) is a particular type of emulsion which is obtained by applying high shear to a mixture comprising two immiscible liquid phases (for example oil and water), one or more surfactants and, possibly, one or more co-surfactants (typical examples are hexadecane or cetyl alcohol). They usually have nanodroplets with uniform size distribution (20–500 nm) and are also known as sub-micron, mini-, and ultra-fine grain emulsions.
