✦ Synopsis

Densities, viscosities, and diffusion coefficients were measured for two aqueous surfactants, pentaethyleneglycol-1-hexyl ether (C 6 E 5 ) and the sodium salt of 1-hexanesulfonic acid (C 6 SO 3 Na),

through the critical micelle concentration range, and the results were briefly discussed. The micellization process was treated as an equilibrium. The diffusion data could be well fitted using a

If n is sufficiently large, the equilibrium model also prequite narrow range of association numbers, n, and equilibrium dicts the onset of micellization in a very narrow range of constants, K.
