Particle size of microemulsion
WebPCS was used to follow the dynamic process of formation and breaking of such systems with droplet diameters of 5-200 nm by obtaining the mean hydrodynamic diameters. … Web“A microemulsion is a system of water, oil and an amphiphile which is a single optically isotropic and thermodynamically stable liquid solution”. In some respects, microemulsions can be considered as small-scale versions of emulsions, i.e., droplet type dispersions either of oil-in-water (o/w) or of water-in-oil (w/o), with a size range in the order of 5−50 nm in …
