Aqueous dilute solutions of 2-butoxyethanol, 1,2-hexanediol, tert-butanol, 1-pentylamine and 1-butylamine are analized through the dynamic light scattering technique. The mutual diffusion coefficient is determined against amphiphile composition, showing, in all cases, clear minima in the dilute region. Using the Stokes-Einstein relation, the mean size of the aggregates is also obtained as a function of mole fraction. For enough concentrated solutions, structures in the range 2-20 angstrom are observed. It is found that both their size and the minimum amphiphile mole fraction for which aggregation is observed are strongly correlated with the hydrophobic character of the amphiphile.
