  • Patent number: 11638681
    Abstract: Provided is a white pigment for cosmetics capable of giving a cosmetic that gives a coating film having less stickiness and higher long-lasting properties. A white pigment for cosmetics of the present invention includes a titanium phosphate powder, the titanium phosphate powder includes crystal particles of titanium phosphate, and a ratio (oil absorption value/specific surface area) of an oil absorption value (ml/100 g) to a specific surface area (m2/g) of the crystal particles is 2.0 or more.

  • Patent number: 11345596
    Abstract: The titanium phosphate powder of the present invention includes plate-shaped crystalline particles of titanium phosphate, an average thickness of the plate-shaped crystalline particles is 0.01 ?m or more and less than 0.10 ?m, and an aspect ratio, which is a value obtained by dividing an average primary particle diameter of the plate-shaped crystalline particles by the average thickness, is 5 or more. In the method for producing a titanium phosphate powder of the present invention, a raw material containing titanium and phosphorus is caused to react by a hydrothermal synthesis method, and when the titanium phosphate powder including plate-shaped crystalline particles of titanium phosphate is produced, a mixture of titanium sulfate and phosphoric acid is used as the raw material.
