There is currently a significant interest in the production of stable emulsions using particulate emulsifiers. A key design and manufacturing challenge such systems with controlled droplet sizes narrow polydispersity; one candidate technique membrane emulsification. In this study we demonstrate that under optimal conditions, highly near monodisperse tricaprylin droplets stabilised 800 nm silica colloids can be achieved Rotating Membrane Emulsification (RME). We report influence various mechanical chemical parameters on size distributions. The conditions for distributions RME approach are described. Investigating rotational speed particle concentration particular highlights importance adsorption kinetics onto growing detachment from membrane. data clearly show if particles attach adsorb to interface before critical time, produced. However, time takes longer than value, partially stabilized coalesce observe wider distribution.
