A method for obtaining a composite powder composed of minerals and a technique relating to the compounded cosmetic are disclosed. Also, JP-A-63-135325 and JP-A-5-20

[0003]

As described above, it is almost known to manufacture cosmetics by using a powder modification technique using a spray dryer.
As described in paragraph number 0013 of Japanese Patent Publication No. 830, various conditions need to be appropriately selected in order to obtain a target quality, which is difficult in operation. In general, powder is coated with an oil agent, which is a water-repellent material, by emulsifying it with a surfactant, but the surfactant promotes the pigment to wet the sebum. As a result, the makeup may be lost. Further, if the oil agent is present alone without being coated around the pigment, there is a problem that when spray-dried, hard particles of the oil agent alone are mixed, giving the cosmetics a rough or uncomfortable feeling.

[0004]

Means for Solving the Problems In view of these problems, the present inventors have made intensive studies and as a result, put a solid or paste-like oil agent into an aqueous solvent and heated it to dissolve and liquefy the oil agent. A system with an aqueous solvent is obtained (the oil and water are separated at this stage). When the pigment is put into this and stirred, under heating, the liquefied oil does not separate from the water and efficiently surrounds the pigment. Found that there is a phenomenon of sticking to the pigment, and spray-drying with a spray drier in this state can easily obtain a composite pigment composed of a pigment and an oil agent, and its quality is uniform, and precipitation of only a solid oil agent hardly occurs. I found that. Furthermore, it has been found that, when a small amount of liquid oil is blended together with the solid oil, the particle bonding force of the solid oil is weakened, and particles that easily collapse on the skin and have an excellent feel are obtained. Then, when a hydrophilic polymer is blended here, the oil agent adheres around the pigment, but since the hydrophilic polymer is dissolved in the aqueous medium, when spray-dried in this state, the outside of the pigment is The present inventors have found that a composite pigment in which an oil agent is covered and a hydrophilic polymer is covered on the outside thereof is obtained, and a cosmetic having excellent feeling of adhesion to the skin and excellent makeup is obtained.
