Zusammenfassung:	A production method for making powder cosmetics having improved characteristics. The method includes mixing a powder component and an oil component as a binder using a mixing apparatus. The mixing apparatus is a facing rotor type mixing apparatus having a first rotor with a plurality of blades and a second rotor with a plurality of blades in a mixing chamber. The first rotor and the second rotor face each other and have rotating shafts on the same axis line. In the facing rotor type mixing apparatus, raw materials are fed into an introduction opening on a first rotor side. The raw materials are mixed by rotating the first rotor and the second rotor in the same or opposite directions to each other, and the mixed raw materials are discharged from a discharge opening on a second rotor side.
