抄録

As a part of a series of studies on the surface activation of medicinals, higher alkylsulfates of l-lysine were synthesized. In this report, physicochemical properties of these compounds were investigated from the view point of pharmaceutical preparation.<br>With increasing number of carbon atoms in the alkyl group, the salts become sparingly soluble in water at room temperature, displaying Krafft's phenomenon, one of the characteristics of ionic surfactants, showing a sudden elevation of solubility at a certain temperature.<br>They form a micelle in aqueous solution and indicate a strong surface activity. They were stable and less hygroscopic in the form of powder.<br>They were found to have more efficiency of emulsification and solubilization for fatty-soluble vitamin than that of sodium alkylsulfate.
