A spin-probe study of the modification of the hydration of SDS micelles by insertion of sugar-based nonionic surfactant molecules

Article Abstract:

Issues concerning the linear decrease of the spin-probe detected polarity index of sodium dodecyl sulfates micelles with the number of inserted sugar-based nonionic surfactant molecules are reported.

Surfactant- and salt-induced growth of normal sodium alkyl sulfate micelles well above their critical micelle concentrations

Article Abstract:

Research is presented concerning the use of time-resolved fluorescence quenching to verify the growth of sodium alkyl sulfate micelles, with added salt, at well above critical micelle concentrations.

Estimate of the ionization degree of ionic micelles based on Krafft temperature measurements

Article Abstract:

A study is conducted to demonstrate that the Krafft temperature, T(sub k) can be used to estimate the degree of counterion dissociation of ionic micelles, alpha. The findings indicate that the Krafft temperature of ionic surfactants is one of the properties from which alpha can be derived for both anionic and cationic micelles.
