Summary

Aqueous solutions of a non-ionic detergent, cetomacrogol, have been studied by ultracentrifuge, light scattering, viscosity, and diffusion. The hydrodynamic data obtained have been investigated with reference to the micellar shape and hydration. Results indicate that the maximum asymmetry which could occur in the micelle when treated as an ellipsoid of revolution would be an axial ratio of 2∶1.

Zusammenfassung

Wäßrige Lösungen des nichtionogenen Detergens Cetomacrogol wurden untersucht durch Ultrazentrifugieren, Messung der Lichtstreuung, Viskosität und Diffusion. Die resultierenden hydrodynamischen Daten wurden in Beziehung gesetzt zu Gestalt und Hydratation der Micellen. Aus den Ergebnissen geht hervor, daß bei Betrachtung der Micelle als Rotationsellipsoid die maximale Asymmetrie bei einem Verhältnis der Achsen von 2∶1 erreicht ist.
