Abstract Multiple emulsions have significant potential in myriad applications, including foods, cosmetics, drop networks, controlled microreactors, synthesis of microcapsules and drug delivery systems. Great control of multiple-emulsion drops production can be achieved using microfluidic devices. The field of emulsification through microfluidic devices has in recent years become a popular topic of research.\n In this work, we used a practical approach to make monodisperse double-emulsions drops with an ultrathin middle layer using a single step emulsification in a capillary microfluidic device. The goal of this study was to investigate the influence of different surfactants and additives on stability and droplet size of W/O/W eco-friendly emulsions formulated with a green solvent (D-Limonene). The incorporation of Pluronic F108 destabilised the double emulsions due to a process of precipitation, forming microcapsules. By contrast, there was a necessity to include Span 80 in the formulation in order to achieve stable double emulsions. The addition of rosin gum or silicone oil did not show any improvement in the stability of these complex emulsions. Finally, the formulation used in ultrathin shell microfluidic device did not produce stable double emulsions in the traditional microfluidic device.
