難である。BACKGROUND OF THE INVENTION Cosmetic pigments whose powder surfaces are coated with chitosan and methods for producing the same have been known. For example, a technique has been disclosed in which powder is coated with chitosan, which is often used in cosmetics, by a wet processing method (Japanese Patent Laid-Open No. 62-223108). On the other hand, as a dry coating method for powder, mechanochemical methods such as mixing and compression are now common methods. However, when performing a dry mixing process using mixing compression, the modification effect is greatly influenced by the particle size distribution of the outer wall powder, and it is difficult to perform a uniform coating process using powder with a wide particle size distribution.

も広い（１〜１００μ）ものであった。[0003] Furthermore, an application for a method for producing fine chitosan powder having a particle size of 1 to 100 μm has been disclosed (Japanese Patent Laid-Open Publication No. 63-27501). On the other hand, regarding chitin, which is the source of chitosan, an application has been disclosed as fine powder chitin with a particle size of 20 μm or less (Japanese Unexamined Patent Publication No. 179901/1983). Chitosan is a deacetylated product obtained by heating chitin, which is obtained by processing the shells of crustaceans and insects that exist in nature, with a concentrated alkali. Not constant. Therefore, it is difficult to control the particle size using these methods. Furthermore, the particle size distribution was wide (1 to 100 μ).

た。[0004] The conventional methods as described above have many unresolved problems such as agglomeration of powder during the coating process and incomplete coating due to non-uniform particle size distribution. Therefore, it has been difficult to prepare chitosan-coated powder by the above-mentioned dry processing method using conventional techniques.

In this way, an attempt was made to enable complete coverage by dry treatment of chitosan.

This makes it possible to more effectively exhibit the effects of a moist finish.

られる。Effects of the Invention According to the present invention, organic spherical powder coated with fine chitosan particles as described above can be obtained. This particulate chitosan-coated organic spherical powder has a small particle size ratio between the chitosan powder and the organic spherical powder, and the organic spherical powder is uniformly coated with the chitosan powder. In addition, since this treatment method is a dry method, the organic spherical powder is coated with fine chitosan powder without re-agglomeration of the powder, without impairing the feel of the conventional organic spherical powder. We were able to modify the surface of organic spherical powder to make it hydrophilic. Therefore, make-up cosmetics containing organic spherical powder whose surface has been modified to be hydrophilic with chitosan powder through dry processing have the advantage of having the smooth, easy-to-spread texture of organic spherical powder, and the smooth feel of organic spherical powder. You can obtain a product that has an excellent feeling of use: firmness, good adhesion to the skin, and a moist finish.
