Abstract
Cetomacrogol solutions have been studied by three techniques. The micellar weight in water has been found from light-scattering experiments to be 101,000; the micelles appear to be spherical. Viscosity measurements can be interpreted in terms of micellar hydration, and 1.96 g. water appear to hydrate 1 g. of cetomacrogol. A similar amount of hydration (1.92 g. water per g. cetomacrogol) can be calculated from the diffusion coefficient. A check on the micellar weight was obtained from the diffusion and viscosity results, giving 96,000, in good agreement with the result from light-scattering.Keywords
