Abstract

L'invention concerne un procédé de formation d'une nanodispersion stable, le procédé comprenant les étapes qui consistent à : (a) prévoir un fluide hôte, un fluide de particules destiné à être dispersé dans le fluide hôte et un agent de stabilisation et (b) faire subir au fluide hôte, au fluide de particules et à l'agent de stabilisation une opération de fractionnement qui forme une dispersion de particules du fluide de particules dans le fluide hôte, les particules du fluide de particules ayant un diamètre moyen de Sauter d'essentiellement 100 nm ou moins, la quantité d'agent de stabilisation que contient le fluide correspondant essentiellement à la quantité qui occupe l'interface entre les particules du fluide de particules et le fluide hôte.
