“…On the other hand, the effect of surfactants on the CAC of alcohols is almost nonexistent suggesting that the interaction between alcohol molecules in water is probably stronger than the interaction between alcohol and surfactant. 20 The effect of alcohols on surfactant micellization can be rationalized in terms of penetration power of alcohol molecules into the stern layer of micelles and the solvent modifying ability of alcohols, the relative magnitude of both of which depends on the concentration of the alcohol used. 21,22 It is known that the volumetric properties serve as important tools which allow us to gain insight into the various solute−solute and solute−solvent interactions occurring in mixed systems.…”

“…A prominent effect of the short chain alcohols on the critical micellization concentration (CMC) of the surfactants is known, with an inhibition of micellization being observed when short chain alcohols are present at concentrations higher than their critical aggregation concentration (CAC).

The work attempts to gain an insight into the solution behavior of a biocompatible surfactant, sodium lauroylsarcosinate (SLS), in aqueous alcohol media at practically used concentrations of SLS (>CMC) where the solute−solute and solute−solvent interactions of surfactant aggregates are expected to be different from that between the solvent and the constituent monomers. The study of volumetric properties stresses the importance of hydrophilic and hydrophobic interactions operative between the SLS molecules and between SLS and the solvent. Moreover, it is interesting to observe how the dominance of electrostatic interactions fades and that of hydrophobic interactions rises as the concentration of SLS is progressively increased. Also, the study of standard apparent molar volumes, and the standard volumes of transfer offers a convenient way for accounting the differences between the alcohols which stems from their differing hydrophobicity.
