Evaluacion experimental del factor de estabilidad en nanoemulsiones dodecano/agua

The turbidity of four different oil/water (o/w) ionic nanoemulsions is studied as a function of time. The emulsions are stabilized with sodium dodecyl sulphate, and are composed of pure dodecane, and mixtures of dodecane, squalene and tetrachloroethylene. For each system plots of the stability factor as a function of the ionic strength of the solution are reported. The results allow establishing the relative importance of buoyancy and Ostwald ripening on the aggregation rates.
