Abstract
A composition for external use containing a tranexamate as an active ingredient with suppressed sticky or oily feeling but having a fresh feel of use, and a method for producing the same. A tranexamate salt can be dispersed stably in an aqueous medium by (a) dissolving the tranexamate salt and an amphiphilic polymer in water, a water-soluble organic solvent or a mixture thereof; and (b) adding a mixed solution obtained in the step (a) to an aqueous medium, and thus keeping the tranexamate salt in molecular assembly particles formed of the amphiphilic polymer.
