Membrane emulsification

Crossflow and rotating membrane emulsification techniques were used for making oil-in-water (O/W) emulsions. The emulsions produced from a variety of oils and monomers (viscosity 7–528 mPas) exhibited narrow size distributions over a wide droplet size range, with the average droplet size ranging fro

Micro/sub-micron emulsion and related systems have received a lot of attention in the last years for their common use as vehicles for topical administration. These systems can be defined as fine emulsion dispersion with droplet sizes in the sub-micron range. The main advantages of such systems are h

In the present paper we illustrate applications of a new set of force balance equations able to predict the average size of a droplet forming during cross-flow membrane emulsification processes. These balance equations allow to correlate the droplet diameters with the advancing and receding contact

There has been an increasing interest in a new technique for making emulsions known as membrane emulsification, which uses a microporous membrane operated in cross-flow. The continuous phase is pumped along the membrane and sweeps away dispersed phase droplets forming from pore openings as shown in

Shirasu-porous-glass (SPG) membranes with a mean pore size from 0.4–6.6 µm were used to produce O/W emulsions consisting of vegetable (rape seed) oil as the dispersed phase and Span 80 dissolved in demineralized water as the continuous phase. The emulsion droplets with a mean droplet size 3.5 times
