Amphiphilic substances can also change the solubility of
water in gasoline. As they are used in small concentrations,
their effect upon the polarity of gasoline can be rather
neglected. Moreover, when having an appropriate structure
and in the presence of hydrophilic modifiers, they can form
reversed micelles presented in Fig. 2. The hydrophilic heads
of surfactants form the micelle cores that can be filled with
water in such a way that the solubility of water can be drastically
changed. Moreover, the effect depends on hydrophilic
additives, some of which can be considered as cosurfactants.
Such additives are incorporated in the reversed
micelles increasing their size, the content of water and,
under special conditions, promoting the charge of the
structure with formation of a microemulsion.
