Prediction of critical micelle concentration of cationic surfactants using connectivity indices

Abstract

Relationship for predicting Logcmc for cationic surfactants having chloride as counterion from only molecular connectivity indices was found. It is suggested that the index 0χν includes some information about hydrophobicity while indices 4χpc and 4χνpc include some information about hydrophilicity of the cationic surfactants studied. The structures of 23 compounds used for the correlation are quite diverse. © 2010 The Author(s).
