The solubilization of oleic acid in the aqueous solution of sodium dodecyl sulfate was studied in the presence of various kinds of alcohols in various concentrations. When the concentration of alcohols in the detergent solution is not so great, the solubility of oleic acid decreases as the amount of alcohols increases. This is explained by the solution of oleic acid and alcohols in the same place in the micelle, i. e., in the palisade layer. When the water soluble alcohols are used the solubilization of oleic acid turns out to increase at a certain concentration of the alcohols in the detergent solution. This is explained by the solution of oleic acid in the solvent liquid as well as in the detergent micelles.
