Interaction between nonpolar surfaces in solutions of the cationic and nonionic surfactant mixtures

Abstract

The interaction energy have been measured between hydrophobic silica particles in aqueous solutions of cationic (dodecylpyridinium bromide) and nonionic (Triton X-100) surfactants and their mixtures. The effect of synergism with respect to interaction energy hydrophobic surfaces has been observed in mixed solutions. The values of interaction parameters were calculated based on ROSEN model. The chain-chain interactions between nonionic and cationic surfactants have been proposed to be main reasons for the observed synergism.
