Title (EN) TITANIUM DIOXIDE POWDER AND POWDER COSMETIC INCORPORATING SAME
(FR) POUDRE DE DIOXYDE DE TITANE ET PRODUIT COSMÉTIQUE EN POUDRE L'INCORPORANT
(JA) 二酸化チタン粉体およびそれを配合した粉末化粧料
Abstract:
(EN) Provided is a powder cosmetic that gives an excellent finish and has an excellent usability and that, while maintaining hiding power, exhibits an excellent capacity to be more transmissive of light in long wavelength regions (selective red light transmission capacity). The titanium dioxide powder according to the present invention is particles in which the apparent average particle diameter is at least 100 nm but less than 500 nm, the average crystallite diameter measured by x-ray diffraction is 15-30 nm, the specific surface area of 10-30 m2/g, and a ratio between the long diameter and short diameter of the shape (long diameter/short diameter) of 1.0-2.5, and the particles have a shape in which radially projecting needle-shaped projections are aggregated. The powder cosmetic incorporates the titanium dioxide powder.
(FR) L'invention concerne un produit cosmétique en poudre qui donne une excellente finition et a une excellente facilité d'utilisation et qui, tout en maintenant la puissance de dissimulation, présente une excellente capacité d'être plus transmissive de lumière dans des régions de longueur d'onde longue (capacité de transmission de lumière rouge sélective). La poudre de dioxyde de titane selon la présente invention est des particules dont le diamètre moyen de particule apparent est d'au moins 100 nm mais inférieur à 500 nm, le diamètre moyen de cristallite mesuré par diffraction des rayons x est de 15 à 30 nm, la surface spécifique de 10 à 30 m2/g, et un rapport entre le grand diamètre et le petit diamètre de la forme (grand diamètre/petit diamètre) de 1,0 à 2,5, et les particules ont une forme dans laquelle des saillies en forme d'aiguille faisant saillie radialement sont agrégées. Le produit cosmétique en poudre incorpore la poudre de dioxyde de titane.
(JA) 仕上がりと使用性に優れ、隠蔽力を維持しつつ、長波長領域の光をより透過する機能(赤色光選択透過機能)に優れた粉末化粧料を提供する。 見かけ上の平均粒子径が100nm以上、500nm未満、X線回折法で測定される平均結晶子径が15~30nm、比表面積が10~30m2/gであって、放射状に突出した針状の突起が凝結した形状を有する粒子であって、形状短径と長径の比(長径/短径)が1.0~2.5である二酸化チタン粉体およびそれを配合した粉末化粧料。
