Microemulsions are colloidal systems which are made by a dispersion of minute droplets (a few hundred Å in diameter) of one component (water) in a continuous medium formed by another immiscible component ( e.g . oil); the droplets are surrounded by a mixed film of surfactants. New information has been obtained about the distribution of the various components in the interior of the droplets. In contrast to other methods, this information is not dependent on interparticle correlation. There is profound penetration of the continuous phase in the interracial film and the droplets are poorly correlated.
