Abstract

Dielectric measurements on a micelle-forming material such as an ionic paraffin chain salt, sodium dodecyl sulfate, SDS, illustrate that there is a dielectric dispersion above the critical micelle concentration, CMC. The dielectric increment varies linearly with the SDS concentration while the relaxation time for the dispersion remains relatively constant over a wide range of concentration. The dispersion is attributed to a shell of bound water around the hydrocarbon core of the micelle. The large constant dielectric decrement produces for the assumed inhomogeneous models a large amount of bound water.
