For this reason, when silicone elastomer powder is blended in cosmetics, it is difficult to disperse sufficiently, and there is a problem that aggregates are generated like foreign substances in cosmetics, and the feeling of stretching, slipping, etc. is poor. . In addition, when the dispersibility of the silicone elastomer powder is poor, internal distortion may occur, and when it is a solid powder foundation, impact resistance may be extremely inferior, resulting in problems in portability as a product. .

- a method using an impact action a method of applying an impact with a hammer mill, a pin mill or the like has been proposed (see, for example, Patent Documents 3 to 5).
- the method of stirring and mixing with a mortar, a grinder, and a ball mill has a problem in that static electricity is generated and re-aggregates if mixed for a long time with low shearing force.
- the latter method of impacting with a hammer mill, pin mill, etc. has the problem that the rubber elasticity of the silicone elastomer powder absorbs the impact force and the fine powder is insufficient.
- Patent Documents 6 and 7 propose a method of using a closed multi-stage shear type shear extruder as a means for industrially producing this method.
- Patent Citation 8 proposes a type crusher such as a cutter mill, a turbo mill, an impeller mill, etc. having both a shearing mechanism and a classification mechanism.
- This method requires two types of equipment, consisting of a pretreatment step in which inorganic minerals and a silicone elastomer powder are roughly mixed in advance and a dispersion step in a dry pulverizer.
- a cutter mill is used as a dry pulverizer, the cumbersome operation of scraping off the silicon composite powder adhering to the inside of the equipment becomes a problem of productivity, and further, the quality problem that the adhering material is mixed into the product. There was also a point.
