The critical micelle concentrations (CIVIC), of heptacainium chloride in various 0.5 M alcohols (methanol, ethanol and n-propanol) were determined using spectrophotometric measurements. CMC values were determined through the change in the slope when the absorbance versus surfactant concentration was plotted at 234 nm. The CMC values show that micelle formation occurred more easily in methanol than in other higher alcohols.
