Presents a broad survey of the properties, behaviour, and modelling of mixed surfactant systems, including mixed micellar solutions, phenomena at interfaces, phase behaviour, and mixtures with unusual surfactant types. Covers chemical reactions in mixed micelles, approaches to molecular modelling of mixed surfactant aggregates, and new experimental techniques for studying mixed micelles and adsorption on surfaces. Features contributions from leading specialists in colloid and surface science, including Robert S. Schechter, John F. Scamehorn, Milton J. Rosen, Keizo Ogino, and Denver G. Hall.
