There, of course, remains the possibility that all the events discussed as above may participate concurrently in smaller or greater degrees in an emulsification process. Furthermore, if an oil containing a surfactant is brought into contact with an aqueous phase, water may diffuse in the oil triggering an aggregation of a surfactant and then its precipitation out of the solution, either as crystal or amorphous aggregate. When these precipitates come into contact with the oil-water interface, it would deliver surfactants to the interface rendering it to be locally supersaturated.
