TL;DR: Cloud point/phase inversion temperature experiments suggested that the higher molecular volume oils were incorporated into the microemulsions prepared using the polyoxyethylene-based surfactants in a different way than the smaller molecularVolume oils and suggest that the smaller Molecular volume oils are acting in much the same way as a cosurfactant in that they interchelate with their hydrophilic group interspersed in the surfactant head group region.

TL;DR: In this paper, a pseudo-ternary phase diagram was constructed for systems comprising of water-lecithin-alcohol-isopropyl myristate, which was shown to have monophasic, isotropic, non-birefringent area along the surfactant/oil axis.

TL;DR: This review highlights the work to date investigating the potential of microemulsions as drug cariers and also reports on preliminary studies performed on the use of vesicles formed from nonionic surfactants.

TL;DR: The phase behavior of quaternary systems composed of lecithin/isopropyl myristate/water/cosurfactant, at a LeCithin: cosurfactants mixing ratio (Km) of 1:1 (on a weight basis) have been investigated by the construction of phase diagrams as mentioned in this paper.

TL;DR: In this paper, phase studies have been performed for quaternary systems composed of egg lecithin, cosurfactant, water and oil, and the phase behaviour observed was largely dependent upon the alcohol and Km used and the size and the polarity of the oil present.
