ResumoABSTRACT The influence of increasing amounts of alcohol on the collective diffusion coefficient was investigated using a light scattering technique. Three components were mantained fixed (isopropyl myristate, sodium bis-S-ethylhexyl sulphosuccinate, water ) series of microemulsions were obtained adding increasing aliquots of alcohol (1-butane isobutanol, 2-pentanol, 3-pentanol, 3-methy1-2-butanol, tert-amylalcohol, cyclo-peintanol, 3-methy 1-3-pentano 1, cyclohexanol, benzyl alcohol( The behaviour was the same for all the series, a maximum of collective diffusion coefficient was noted for each alcohol. The collective diffusion coefficients at maximum could be related to the water solubilities of the alcohols.
