Title (EN) SOLID POWDER COSMETIC
(FR) PRODUIT COSMÉTIQUE DE POUDRE SOLIDE
(JA) 固形粉末化粧料
Abstract:
(EN) The problem to be solved by the present invention is to provide a solid powder cosmetic which has excellent impact stability, finish, and usability, and which, while maintaining hiding power, has an excellent function of transmitting more light in a long-wavelength region (red light selective transmission function). This solid powder cosmetic is characterized by containing: 1-30 mass% titanium dioxide powder consisting of particles which have an apparent average particle diameter of greater than or equal to 100 nm and less than 500 nm, an average particle diameter of 15-30 nm measured by x-ray diffraction, a specific surface area of 10-30 m²/g, and a shape of coagulated radially projecting needle-shape protrusions, the ratio of the long diameter and the short diameter of the shape (long diameter / short diameter) of said particles being 1.0-2.5; 5-30 mass% of a spherical powder; and 5-40 mass% of a powder surface treated with a metal soap, or elastomers formed from component (A) and component (B) described below. The elastomers are formed from (A) a silicone polymer having an amino group and (B) a silicone polymer having a carboxyl group or an acrylic polymer having a carboxyl group, wherein the molar ratio Y/X of amino groups and carboxyl groups is within the range between 0.1 and 1.2 (Y is the number of moles of carboxyl groups contained in component (B), and X is the number of moles of amino groups contained in component (A)).
(FR) Le problème que cherche à résoudre la présente invention est de fournir un produit cosmétique de poudre solide qui a une excellente stabilité au choc, un excellent aspect fini et une excellente facilité d'utilisation, et qui, tout en maintenant un bon pouvoir de dissimulation, a une excellente capacité à transmettre plus de lumière dans la zone des longueurs d'onde longues (fonction de transmission sélective de la lumière rouge). Ce produit cosmétique de poudre solide est caractérisé en ce qu'il contient : 1 à 30 % en masse de poudre de dioxyde de titane constituée de particules possédant un diamètre particulaire moyen apparent supérieur ou égal à 100 nm et inférieur à 500 nm, un diamètre particulaire moyen tel que mesuré par diffraction des rayons X compris entre 15 et 30 nm, une surface spécifique comprise entre 10 et 30 m²/g, et une forme de protubérances coagulées en forme d'aiguille faisant saillie radialement, le rapport du grand diamètre et du petit diamètre de la forme (grand diamètre / petit diamètre) desdites particules étant compris entre 1,0 et 2,5 ; 5 à 30 % en masse d'une poudre sphérique ; et 5 à 40 % en masse d'une surface de poudre traitée avec un savon métallique, ou des élastomères formés à partir d'un composant (A) et d'un composant (B) décrits ci-dessous. Les élastomères sont formés à partir de (A) un polymère de silicone possédant un groupe amino et (B) un polymère de silicone possédant un groupe carboxyle ou un polymère acrylique possédant un groupe carboxyle, le rapport molaire Y/X des groupes amino et des groupes carboxyle étant situé dans la plage comprise entre 0,1 et 1,2 (Y correspond au nombre de moles de groupes carboxyle contenues dans le constituant (B), et X correspond au nombre de moles de groupes amino contenues dans le constituant (A)).
(JA) その解決すべき課題は、衝撃安定性、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)に優れた固形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を1~30質量%と、 球状粉末5~30質量%と、 下記(A)成分と(B)成分からなるエラストマーまたは金属石鹸表面処理された粉末を5~40質量%と、を含むことを特徴とする固形粉末化粧料。 (A)アミノ基を有するシリコーンポリマーと、 (B)カルボキシル基を有するシリコーンポリマー又はカルボキシル基を有するアクリルポリマーと、 からなるエラストマーであって、アミノ基とカルボキシル基のモル比が、Y/X=0.1~1.2 (Yは、(B)成分に含まれるカルボキシル基のモル量、Xは、(A)成分に含まれるアミノ基のモル量)の範囲にある
