Aggregation behavior of ionic surfactant micelles in aqueous alcoholic solutions at different temperatures

Journal Article · · J. Colloid Interface Sci.; (United States)
In some recent studies Vikingstad has pointed out that when water-soluble alcohols are dissolved in aqueous micellar solutions, most of the alcohol molecules are solubilized in the micelles, thereby decreasing the aggregation number. A literature study has been made on the effect of different n-alcohols on either the average micellar molar mass, M, or the average aggregation number, N. The conclusion is that addition of small amounts of alcohol may increase the aggregation number. Larger amounts of water-soluble alcohols (methanol, propanol) seem to decrease N, while sparingly soluble alcohols (octanol, dodecanol) seem to increase N. With very large amounts of water-soluble alcohols there is no evidence of micelle formation.
