Summary:Provided is an ultraviolet-shielding particle, the surface of which is coated with a silicon oxide film, wherein at least one functional group selected from the group consisting of an alkyl group, an alkenyl group, and a cycloalkyl group is present on the surface of the silicon oxide film, and the content of the functional group is 0.0001-0.30 mass%. L'invention concerne une particule de protection contre les ultraviolets, dont la surface est revêtue d'un film d'oxyde de silicium, au moins un groupe fonctionnel choisi dans le groupe constitué par un groupe alkyle, un groupe alcényle, et un groupe cycloalkyle étant présent sur la surface du film d'oxyde de silicium, et le contenu du groupe fonctionnel est de 0,0001 à 0,30 % en masse. 本発明の酸化ケイ素被覆紫外線遮蔽粒子は、紫外線遮蔽粒子の表面が酸化ケイ素被膜で被覆されてなり、前記酸化ケイ素被膜の表面に、アルキル基、アルケニル基およびシクロアルキル基からなる群から選択される少なくとも1種の官能基が存在し、前記官能基の含有量が0.0001質量%以上かつ0.30質量%以下である。
