[0007] On the other hand, although microparticle titanium oxide is compounded in cosmetics for the purpose of UV protection by utilizing the ultraviolet shielding ability of microparticle titanium oxide, its defense effect is weaker than that of organic ultraviolet absorbers for the same purpose. For high UV protection effect, it is necessary to increase the compounding amount
Therefore, there is a concern that unnatural paleness and the like may occur when a UV protection cosmetic containing conventionally commercially available fine-particle titanium oxide is applied to the skin.
In addition, although conventional microparticle titanium oxide shields the wavelength of the UV-B region (320nm to 290nm), it does not sufficiently shield the UV-A region (400nm to 320nm).

Embodiment 1
[0075] Among the plurality of doping elements selected based on first-principle calculations including the above-mentioned first step and second step, experiments were performed on Zn, Fe, and Ni. That is, in InTaO 4 Materials doped with Zn, Fe, and Ni were used as test objects, and the experiments shown below were carried out. In addition, as a comparison, for undoped InTaO 4 and TiO 2 Do the same experiment.
[0076] The ultraviolet absorber according to the present embodiment can be synthesized by a conventional solid-state reaction method, that is, by mixing metal components as raw materials at a target composition ratio and firing in air under normal pressure. In addition, various methods such as various sol-gel methods and complex polymerization methods using metal alkoxides and metal salts as raw materials can be used. Here, the solid-phase reaction method was used for the preparation of the sample of the ultraviolet absorber. The amount of doping elements was set ...

[0082] Next, using the same method as in Example 1, the InTaO 4 Doped Mo, La material, InTaO 4 Materials doped with Zn and Fe, InTaO 4 The material doped with Zn and In was used as the experimental object for the experiment. In addition, as a comparison, for undoped InTaO 4 Do the same experiment. Here, 10% of the dopant element was introduced.

Abstract
Provided are: an ultraviolet absorbent that has sufficient blocking effect with respect to UV-A and UV-B and is capable of providing a natural color that is suited to the skin on which the ultraviolet absorbent is applied, said ultraviolet absorbent being suitable for use by a person with dark skin; and a cosmetic preparation that uses the ultraviolet absorbent. An ultraviolet absorbent which is obtained by introducing at least one element selected from the group consisting of Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, Ge, As, Y, Zr, Nb, Mo, Tc, Ru, Rh, Pd, Ag, Cd, Sn, Sb, Hf, W, Re, Os, Ir, Pt, Au, Hg, La and In, in an amount of 10% or less, into A and / or B of a compound that is represented by general formula ABO4 (wherein A represents In, Bi, Ga or Gd, and B represents Ta, Nb or V).
Description
technical field [0001] The present invention relates to a cosmetic having ultraviolet absorbing properties and a method for producing the cosmetic. Background technique [0002] Conventionally, ultraviolet rays are known to cause various changes in the skin. In skin science, the action wavelengths of ultraviolet rays are classified into long-wave ultraviolet rays from 400nm to 320nm, medium-wave ultraviolet rays from 320nm to 290nm, and short-wave ultraviolet rays below 290nm, which are called UV-A, UV-B and UV-C respectively. [0003] Usually, most of the ultraviolet rays irradiated to human beings are sunlight, and among the ultraviolet rays, the ultraviolet rays reaching the earth's surface are UV-A and UV-B, and UV-C is absorbed in the ozone layer, so hardly reaches the earth's surface. Among the ultraviolet rays that reach the surface, UV-A and UV-B, if the amount of light above a certain level is irradiated on the skin, it will cause changes such as the formation of e...
