摘要
The present invention provides a silicone elastomer composite powder with excellent flowability and dispersibility. Also, the present invention provides a method for producing a silicone elastomer composite powder, comprising a step of converting a mixture of a silicone elastomer powder and a clay mineral to the composite powder with a high-speed rotation dispersing machine under a condition of a peripheral speed of 40 m/sec or higher and a Froude number of 70 or higher, wherein a surface of the silicone elastomer powder is coated with the clay mineral, a specific volume of the composite powder is 2.50 ml/g or less, and an oil absorption amount of the composite powder is 180 g/100 g or less. Furthermore, the present invention provides a cosmetic without sticky feeling inherent in the silicone elastomer powder, and excellent in the feeling during use and in impact resistance.
