Solubilization of benzene derivatives in silicate-surfactant systems

The solubilization of six polar benzene derivatives with different polar groups by a silicate-surfactant mesophase has been investigated. Depending on the nature of the polar group of the solubilizate a transition to the lamellar phase, a contraction or an increased ordering of the hexagonal phase was observed. The results are discussed in terms of a co-surfactant effect paralleled by competitive adsorption of the solubilizate to the silicate.
