Abstract
A composition for external use containing a physiologically acceptable salt of a tranexamate as an active ingredient, which is dispersed in the composition in the state of fine particles, is provided. Thereby, a physiologically acceptable salt of the tranexamate is dissolved in a solvent to prepare a solution, to which a salting-out agent is added to precipitate the salt. Such salt is so dispersed in a composition for external use in the state of fine particles that the tranexamate salt can be mixed without using a large amount of an oil component to obtain a composition for external use affording excellent feel of use and stability.
