  • Publication number: 20120039971
    Abstract: An object of the present invention is to provide a solid powder cosmetic having an excellent effect of preventing makeup running and oily shining, and having a satisfactory long-lasting makeup effect. A solid powder cosmetic comprising: a powder component, an oily component as a binder, and an amide mixture obtained by amidating a mixture of hexamethylenediamine and bisaminomethylcyclohexane with hydrogenated castor oil fatty acids. It is suitable for the solid powder cosmetic that an amount of the amide mixture is 1.0% to 15% by mass. It is suitable for the solid powder cosmetic to comprise 1% to 20% by mass of spherical poly(meth)acrylate particles as the powder component. It is suitable for the solid powder cosmetic to further comprise an organically modified clay mineral in an amount of 1.0% to 15% by mass as a total amount with the amide mixture. It is also suitable for the solid powder cosmetic to comprise 5% to 97% by mass of fluorine compound-treated powder as the powder component.

  • Publication number: 20100316581
    Abstract: To provide skin external preparations characterized in that the initial permeation rate of oil-soluble drugs (e.g. retinol and tocopherol acetate) is controlled to achieve their sustained release to thereby reduce skin irritation and that they also possess a fresh feel while featuring high degrees of safety and stability. A skin external preparation which comprises a finely dispersed, oil-soluble drug containing wax composition, the composition containing a solid or semisolid wax, a nonionic surfactant, an aqueous dispersion medium, and an oil-soluble drug, the mass ratio of the nonionic surfactant to the wax being 1.0 or more, and the wax, with the oil-soluble drug contained therein, being finely dispersed in solid or semisolid form in the aqueous dispersion medium.
