Abstract
(EN)
The present invention provides flake-shaped hydrotalcite-type particles having superior glide and sufficiently reduced ability to cause skin irritation. The present invention also provides a cosmetic containing said flake-shaped hydrotalcite-type particles. The flake-shaped hydrotalcite-type particles are represented by a prescribed structural formula and have an average flake surface diameter of 150-800nm, an aspect ratio (average flake surface diameter/average thickness) of 4.0-20.0, and a pH value of 6.0-8.5 according to the JIS K5101-17-1 (2004) test methods for pigments.
(FR)
La présente invention concerne des particules de type hydrotalcite en forme de paillettes présentant d'excellentes propriétés de glissement et une capacité suffisamment réduite à provoquer une irritation de la peau. La présente invention concerne également un produit cosmétique contenant lesdites particules de type hydrotalcite en forme de paillettes. Les particules de type hydrotalcite en forme de paillettes sont représentées par une formule structurelle prescrite et possèdent un diamètre de surface de paillette moyen de 150 à 800 nm, un rapport d'aspect (diamètre de surface de paillette moyen/épaisseur moyenne) de 4,0 à 20,0 et une valeur de pH de 6,0 à 8,5 conformément aux méthodes de test des pigments de la Norme JIS K5101-17-1 (2004).
