Description

  The present invention relates to an amphiphilic substance-treated flat cellulose powder and a powder cosmetic containing the same, and more specifically, an amphiphile having a flat shape and having a surface treated with an amphiphilic substance. The present invention relates to a functional substance-treated flat cellulose powder and a cosmetic containing the same.

  Powder cosmetics containing a powder component, an oily component and the like are widely used in the field of cosmetics, and examples thereof include powder foundation, eye shadow, powdered white powder, blusher and the like.

  This powder cosmetic is generally produced by filling a powder container of powder components such as extender pigments and pigments and an oil component into a dish-shaped container and press-molding it.

  As the powder component used in this powder cosmetic, natural pigment-derived thin mica pieces, sericite, talc, etc. and surface treated products thereof are extender pigments because they have good elongation and stickiness on the skin. Has been used as. Further, spherical organic powders and the like have been used together with the above extender pigments in order to improve the slip and feel of extender pigments on the skin. Further, white pigments such as titanium dioxide, colored pigments such as Bengala, and glossy pigments such as titanium mica have been used as the pigment.

  Among the powder components, inorganic powders such as mica, sericite, and talc are widely used as flakes, but these are all aluminosilicate minerals and have properties depending on the production area. Are slightly different from each other, for example, there is a problem that the oil absorbability is low or the desired physical properties cannot be obtained. On the other hand, flat organic powders have not been reported so much, for example, to the extent that flat cellulose particles obtained by mixing cellulose-based substances and fatty acids and then mechanically pulverizing them are known. Yes (Patent Document 1).

  However, in this patent document 1, although flat cellulose particles are disclosed, the specific use form is not disclosed, and the application to cosmetics is only disclosed very simply.

  On the other hand, a technique for treating the surface of crystalline cellulose with hydrogenated lecithin is also known (Patent Document 2). However, this crystalline cellulose has a major axis / minor axis ratio (L / D) of 3 or less, which is not flat. In fact, when compared with untreated ones, there is a difference in the goodness of makeup. However, it is disclosed that there is not much difference between “Take”, “Nobi”, and “Finish” that are the feeling of use.
