Description:
The effect of processing protocol on physical stability and the microstructure of W/O/W multiple emulsions containing a mixture of two amphiphilic copolymers with opposed HLB as emulsifiers and a green solvent, 2-ethylhexyl lactate, as dispersed phase, has been assessed. Emulsions were obtained by at least two steps, a homogenization step by using a rotor-stator device followed by one or two homogenization steps carried out in a high-pressure device using Microfluidizer technology. In order to study the microstructure and the physical stability of these emulsions, a combination of different techniques, such as transmitted light optical microscopy, globule size distribution, viscous flow tests, and multiple light scattering measurements were performed.
