色管理の困難性等が大きな問題となっていた。As described above, many studies have been conducted on the modification of pearl pigments. However, in the plate-like base material made by crushing natural products such as talc, mica and sericite, the color tone of the base material itself is an impurity. As a result, the color tone of the product also varies, and the difficulty of color management has become a serious problem especially for products such as cosmetics that emphasize color.

下、本発明を詳述する。Means for Solving the Problems The gist of the present invention is to use plate-shaped barium sulfate having a pearl luster as an average particle size of 3 to 70 μm.
The plate-shaped barium sulfate is coated with titanium dioxide. Further, the gist of the present invention is to suspend the plate-shaped barium sulfate having an average particle diameter of 3 to 70 μm in a titanyl sulfuric acid solution or an aqueous titanium tetrachloride solution and heat it to hydrolyze it to form a plate-shaped barium sulfate surface. There is also a method of producing plate-like barium sulfate having silvery white to lustrous pearl luster by precipitating hydrous titanium oxide and then filtering, washing with water, drying, pulverizing and firing. Hereinafter, the present invention will be described in detail.

る。The average particle size of the plate-shaped barium sulfate used as the substrate in the present invention is 3 to 70 μm. When the average particle diameter is less than 3 μm, white is not produced due to diffused reflection of light to give a pearly tone, and when it exceeds 70 μm, a rough feeling occurs when blended in a cosmetic composition, resulting in poor skin feel.
Since it is difficult to manufacture products with uniform particle size and the color tone varies when coated with titanium dioxide,
It is limited to the above range. It is preferably 20 to 50 μm.

が５以上であるものをいう。The average particle diameter can be determined by averaging the maximum diameters of 50 particles on a straight line drawn randomly on an electron micrograph of barium sulfate. The “plate-like” in the plate-like barium sulfate means that the ratio of the maximum particle diameter to the particle thickness is 5 or more.

る。The plate-shaped barium sulfate having a pearly luster of the present invention is formed by coating the plate-shaped barium sulfate with titanium dioxide. The pearly luster of the plate-like barium sulfate having the above-mentioned pearly luster can change the color tone of silver white to brilliant color by changing the titanium dioxide coating amount in relation to the particle size and the specific surface area of the plate-like barium sulfate. it can.

線遮蔽効果が著しく低下してしまう。In the method for producing plate-shaped barium sulfate having a pearly luster of the present invention, the plate-shaped barium sulfate is added to a titanyl sulfuric acid solution or a titanium tetrachloride aqueous solution and gradually heated to continue boiling. A pearly luster can be obtained by uniformly depositing titanium dioxide on the surface of plate-shaped barium sulfate, filtering this, washing with water, drying and firing for 1 hour or more. The firing temperature is 500 to 90.
0 ° C is preferred. If it is less than 500 ° C, only titanium oxide having a low ultraviolet shielding effect can be obtained, and if it exceeds 900 ° C, scale-like plate-shaped barium sulfate is disintegrated and fused to reduce the dispersibility, or titanium oxide is used. Particle growth occurs, and the ultraviolet shielding effect is significantly reduced.

動車用、家庭用として幅広く利用できる。The titanium dioxide coated with the plate-shaped barium sulfate has an ultraviolet ray absorbing effect, so that the pearl pigment of the present invention itself can significantly block ultraviolet rays and is harmful to the skin when used as a cosmetic product. It has a function of blocking ultraviolet rays, and is particularly useful as an extender for cosmetics having a design property. In addition, the pearl pigment of the present invention can be used as a pearl-like exterior for home electric appliances, as a container, etc. by kneading it into a resin. Furthermore, by blending it with a paint, it can be widely used for automobiles and households.
