Patent number: 9833401Abstract: 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.Type: GrantFiled: July 15, 2011Date of Patent: December 5, 2017Assignee: CHANEL PARFUMS BEAUTEInventors: Masayoshi Miyamoto, Tomomi Kuromiya, Daisuke Suzuki

Patent number: 8758785Abstract: 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.Type: GrantFiled: December 24, 2013Date of Patent: June 24, 2014Assignee: Chanel Parfums BeauteInventors: Masayoshi Miyamoto, Tomomi Kuromiya, Daisuke Suzuki
