Nonionic Micelles in Mixed Water Glycerol Solvent / L.Cantu', M.Corti, V.Degiorgio, H.Hoffmann, W.Hulbricht. - In: JOURNAL OF COLLOID AND INTERFACE SCIENCE. - ISSN 0021-9797. - 116:2(1987), pp. 394-389. [10.1016/0021-9797(87)90134-2]
Abstract:
The aggregation properties of the nonionic amphiphile C12E8 in water-glycerol mixtures are investigated at various glycerol volume fractions X by surface tension, light scattering, refractometry, and viscosimetry measurements. In the range 0 < X < 0.4, the critical micelle concentration increases slowly with X, and the aggregation number m decreases with X. For X > 0.4, the CMC grows considerably, and the Krafft temperature becomes larger than room temperature. The minimum of the cloud point curve decreases from 74°C at X = 0 to 43°C at X = 0.6.
