Abstract:

Dispersion of inorg. (magnesium chloride) nanoparticles in oil (octyl palmitate) was obtained by modifying a method based on solvent evapn. from nanometric droplets of water-in-oil nanoemulsion, which is usually used for obtaining org. nanoparticles. The particles size depends on the initial size of the emulsion droplets, and can be controlled by surfactant concn. and sonication time. At optimal conditions, the obtained nanoparticles are characterized by an av. diam. of about 100 nm (dynamic light scattering and Cryo-TEM), by their amorphous structure when dispersed in oil, and according to thermal gravimetric anal., by not contain free water after the evapn. process. The developed method is applicable for the prepn. of various inorg. nanoparticles, and can be utilized for the formulation of new delivery systems based on inorg. nanoparticles of minerals/salts dispersed in oil.
