Abstract Provided is a boron nitride powder comprising primary particles of BN that form a flat shape and an aggregate body of the primary particles. By setting the water permeation speed to 1 mm2/s or higher and the oil absorption amount in the range of 100 ml/100 g to 500 ml/100 g, a boron nitride powder for use in cosmetics that is rich in hydrophilic properties and highly oil absorbent is achieved. The boron nitride powder is used to obtain a cosmetic in which the glossiness and transparency (resemblance to bare skin) of the applied product as well as lasting power are greatly improved. L'invention porte sur une poudre de nitrure de bore comprenant des particules primaires de BN qui forment une forme plane et un corps aggloméré des particules primaires. Par réglage de la vitesse de perméation de l'eau à une valeur supérieure ou égale à 1 mm2/s et de l'absorption d'huile dans la plage de 100 ml/100 g à 500 ml/100 g, une poudre de nitrure de bord destinée à être utilisée dans des produits cosmétiques qui est riche en propriétés hydrophiles et absorbe fortement l'huile est obtenue. La poudre de nitrure de bore est utilisée pour produire un produit cosmétique, le brillant et la transparence (ressemblance à la peau nue) du produit appliqué ainsi que la durabilité étant fortement améliorés.
