As an environment-friendly surfactant alkyl polyglycosides(APG) -or allkyl polyglucosides have become very attractive due to its excellent surface activity as well as mildness and good biodegradability[1]. In our study, dispersibility of system comprised of alkyl polyglycoside as a surfactant, fuel oil as an oil phase and sea water as a water phase was investigated with the surfactant concentration and its formulation.
