This study aimed to evaluate the influence of Appyclean 6552, an ecological and biodegradable emulsifier, and its use in combination with Ghassoul clay in the formulation of emulsions using linseed oil as dispersed phase. The surface and interfacial activity of Appyclean 6552 were studied and they remain constant above 0.05 wt%, proving the interfacial activity of this ecological emulsifier. Moreover, linseed oil-in-water (15 wt%) emulsions were produced by ultrasonication optimising the processing time and the emulsifier concentration, following the response surface methodology. In addition, centrifugal tests were carried out to quantify the stability of the systems. Interestingly, the optimum for droplet size and stability index was the same (2.21 wt% of Appyclean 6552 and 521 s in ultrasonicator). Finally, it can be observed how the addition of a rheological modifier as Ghassoul clay provokes the formation of a structured system that confers great stability. This study can expand the knowledge about Appyclean 6552 as stabiliser of systems that could be applied to food or pharmaceutical fields. © 2024
