ON METALLIC SOAPS

Journal of Japan Cosmetic Chemists Association, 1966
Metallic soaps have many varieties and many applications.Aluminum soap shows special properties, and its synthetic procedure and application differs from other metallic soaps.When we want to use the dispersions of metallic soap in nonaqueous liquids, we must observe the effects of cation or anion variation on structure and solvent composition.
