Zusammenfassung:	PARTICULAS REVESTIDAS UTILES EN COMPOSICIONES COSMETICAS COMPRENDEN PARTICULAS DE SUSTRATO, UN AGENTE DE ACOPLAMIENTO Y UN REVESTIMIENTO EXTERIOR DE NITRURO DE BORO. UN MODO DE REALIZACION PREFERIDO ESTA CONSTITUIDO POR PARTICULAS DE SUSTRATO ESFERICAS HUECAS DE COPOLIMERO DE POLIVINILIDENO CON ISOPROPIL TRIISOSTEAROILTITANATO COMO AGENTE DE ACOPLAMIENTO. A coated particle useful in cosmetic compositions including a base particle, a coupling agent and an outer coating, and a method of making same. A preferred embodiment comprises hollow spherical polyvinylidene copolymer base particles, isopropyl tri-isostearyl titanate as the coupling agent and boron nitrate powder as the outer coating.
