✦ Synopsis

The micellar behavior of the binary mixed systems of sodium n-hexylsulfate with sodium n-decyl-, n-dodecyl-, and n-tetradecylsulfate has been studied. The critical micelle concentration of the mixtures was quantitatively estimated by conductance methods. The micellar composition in the micelles was determined by the Motomura model and the mutual interactions were estimated from Holland and Rubingh's theory. The surfactant mixtures were found to be nonideal. The influence of the alkyl chain length in these parameters was studied. Copyright 2000 Academic Press.
