【発明が解決しようとする課題】しかし、上記の(1)の
紫外線吸収剤を配合した化粧料では、充分な効果を得る
ためには紫外線吸収剤を多量に配合しなければならな
い。そのために、例えば酸化チタン等を用いる場合に
は、肌に塗布したときに隠蔽力が大きくなりすぎ、白っ
ぽくなって自然さのない化粧仕上がりとなり、さらに、
ざらつき、テカリ、重さ等の感触が悪くなり化粧持ちも
著しく低下する。その上、紫外線吸収剤による皮膚刺激
などの安全性の問題も生じる。However, in the cosmetic composition containing the ultraviolet absorbent of (1) above, a large amount of the ultraviolet absorbent must be mixed in order to obtain a sufficient effect. Therefore, for example, when titanium oxide or the like is used, the hiding power becomes too large when applied to the skin, resulting in a whitish and unnatural makeup finish.
Roughness, shine, weight, etc. feel bad and make-up lasting significantly deteriorates. In addition, safety problems such as skin irritation due to the ultraviolet absorber occur.
【０００６】一方、(2)の球状多孔性樹脂粉体に紫外線
を含有させたものでは、球状粉体の表面そのものの特性
が出て、紫外線吸収剤の効力が充分に発揮させにくいも
のとなる。On the other hand, in the case of (2) the spherical porous resin powder containing ultraviolet rays, the characteristics of the surface of the spherical powder itself appear, and it becomes difficult to sufficiently exert the effect of the ultraviolet absorber. .

紫外線吸収剤を内包させたものでは、粉末そのものがも
つ乱反射効果が優先し、紫外線が紫外線吸収剤まで到達
しにくくなり、紫外線吸収剤の効力が充分発揮できない
もとなることが推定される。Further, in the case of (3) the hollow part of the powder of the vinyl polymer containing the ultraviolet absorber, the diffuse reflection effect of the powder itself is prioritized, and it becomes difficult for the ultraviolet rays to reach the ultraviolet absorber. It is presumed that the efficacy of the agent cannot be fully exerted.
【０００８】(4)の偏平粒状樹脂微粉末に紫外線吸収剤
を含有させたものでは、偏平粒子であるために、球状粉
体に比べて延展性や、化粧料系中での均一分散性が劣
り、むら付きも起こる。The flat granular resin fine powder of (4) containing an ultraviolet absorber has flattening particles, so that the spreadability and the uniform dispersibility in the cosmetic system are higher than those of the spherical powder. Inferiority and unevenness occur.

くなってくずれやすくなるので配合量には限界がある。Further, in order to improve the dispersibility of the powder in the cosmetic, the work of passing a screen of a pulsarizer (for example, a passing mesh of 1 mmφ) is usually carried out, but the inorganic powder of (5), the inorganic spherical powder, Or, the one in which the surface of the organic spherical powder is coated and bonded with the ultraviolet absorbent does not pass through the screen because the spherical powder has a large particle system. As a result, they are mixed after coating with the oil agent, so that the dispersibility is poor and the UV protection effect is not improved. Furthermore, since the coverage of the ultraviolet absorber is low, it is necessary to add a large amount in order to obtain a satisfactory ultraviolet protection effect, but the feel is reduced, the moldability deteriorates and it tends to crumble, so the amount to be added is limited. Has a limit.

The ultraviolet absorber is sprayed while mixing at a low speed of about 00 rpm, and then mixing is performed for 10 minutes. In this way, processed powder is obtained. In the present specification, "coating" includes not only covering the surface of fine particle silica but also impregnating the surface of the fine particle silica into the inside.

下することがある。The coating rate of the ultraviolet absorber on the fine particle silica is preferably 10 to 65% by weight, particularly preferably 30 to 60% by weight, as the amount of the ultraviolet absorber to the processed powder. If the coating rate is lower than this range, a sufficient UV protection effect cannot be obtained when incorporated into a cosmetic. On the other hand, if it is higher than this range, the powder tends to agglomerate in the cosmetic, and stickiness may occur. In addition, the dispersibility in cosmetics may be deteriorated and the ultraviolet protection effect may be reduced.
