  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.
