Fig. 1. A plot of the density () of the aqueous solutions of the TX-100 and CTABmixture with ethanol vs. the logarithm of the ethanol mole fraction in the bulk phase(logX2). Curves 1–4 correspond to the constant TX-100 mole fraction in the mixturewith CTAB equal to 0.2, 0.4, 0.6 and 0.8, respectively.
