Janus emulsions were formed by mixing three immiscible liquids; this implies two oil components (i.e.olive oil (OO) and silicone oil (SiO)) with water in presence of interfacial active components. The mor-phology and size of Janus droplets formed strongly depended on the type of surfactant used. In presenceof a non-ionic surfactant, i.e. Tween 80, large engulfed Janus droplets were formed. By adding phospho-lipids to the system the droplet size was decreased and more stable Janus droplets formed. Interfacialtension measurements carried out using a spinning drop apparatus and a ring tensiometer demonstratethat interfacial tension is the most important factor controlling the size, morphology and stability of Janusdroplets. When the interfacial tension between oil and water becomes ≤1 mN/m, smaller Janus dropletsare formed. Such conditions are fulfilled when phospholipids are used in combination with non-ionicsurfactant Tween 80. The morphology of the double droplets is predominantly controlled by the vis-cosity and interfacial tension between the two oil phases. By using different types of phospholipids, i.e.asolectin and lecithin instead of a more concentrated phosphatidylcholine (phospholipon), the interfacialtension is decreased and different morphologies of engulfing can be observed.
