“…The microemulsions also contain two surfactants (namely sodium lauryl sulphate (SLS) and 2‐methacryloyl‐ethyl‐trimethylammonium methyl sulfate (MTMS)), which are responsible for their stability and thus for the formation of the microspheres. MTMS can enter within SLS micelles or it can be absorbed on their surface thanks to electrostatic interactions . Preliminary attempts performed by using each surfactant individually in the proper medium (i.e.…”

Acrylic microspheres bearing a dense shell were successfully prepared by an in situ microemulsion photoinduced polymerization. Experiments following a fractional factorial design were performed for assessing the effect of the main reaction parameters (surfactant concentration in the aqueous phase, stirring rate, organic to water volume ratio, irradiation time) on the morphology of the microspheres and on their encapsulation yield. Environmental scanning electron microscopy and porosity measurements were carried out. Finally, the drug‐delivery features of the obtained products were investigated, evaluating the release of vanillin, chosen as a reference compound. The diffusion coefficients were found to be almost unvaried despite the increase in BET area. Such products show promising potentialities for home and personal care applications. © 2012 Society of Chemical Industry
