Structure and physico‐chemical properties in mixed aqueous solution of sodium alkylcarboxylate‐alkyltrimethylammonium bromide

The physico‐chemical properties of organized assemblies (micelle or vesicle) from sodium alkylcarboxylate ‐ alkyltrimethyl ‐ammonium bromide mixture have been investigated systematically. In different mixed cationc‐anionic surfactant systems, micelles and vesicles can coexist or be transformed into each other on different conditions. The experimental results are explained prelimilarily from the viewpoint of molecular packing geometry. The solubilization of organic compound in the mixed surfactant system was also studied in detail.
