Ultrasonic absorption measurements have been used to study the dynamics of micellar systems and to obtain semiquantitative information on the kinetic and thermodynamic parameters for the cosurfactant exchange process from mixed micelles of surfactant and cosurfactant. Ultrasonic relaxation parameters for the micellar systems containing water, surfactant (cetyltrimethylammonium bromide, myristyltrimethylammonium bromide, cetylpyridinium bromide, and Dowfax 2A1), and cosurfactant (butoxyethanol) are reported. The kinetic parameters for the exchange of butoxyethanol between the mixed micelles containing cetyltrimethylammonium bromide and myristyltrimethylammonium bromide are estimated and the results are discussed in light of the proposed mechanism.
