A process for preparing particles having a hydrophobic material therein is disclosed. The process comprises providing a multiple emulsion comprising a first emulsion dispersed in a hydrophobic medium, said first emulsion comprising a hydrophobic phase dispersed in a hydrophilic phase, wherein the hydrophobic phase comprises the hydrophobic material and the hydrophilic phase comprises a precursor which is capable of reacting to form a non-fluid matrix and reacting the precursor in the multiple emulsion to form the matrix in the form of the particles having the hydrophobic material therein wherein the precursor is added prior to formation of the multiple emulsion. Also disclosed are particles having a hydrophobic material therein, which may be releasable, as well as particles having a hydrophobic material therein, which may be releasable, made by the process and methods of using the particles.

L'invention concerne un procédé permettant de préparer des particules dans lesquelles est incorporé un matériau hydrophobe. Le procédé consiste à: former une émulsion multiple comprenant une première émulsion dispersée dans un milieu hydrophobe, ladite première émulsion comprenant une phase hydrophobe dispersée dans une phase hydrophile, la phase hydrophobe comprenant le matériau hydrophobe et la phase hydrophile comprenant un précurseur qui est capable de réagir afin de former une matrice non fluide; et faire réagir le précurseur dans l'émulsion multiple afin de constituer la matrice sous forme de particules dans lesquelles est incorporé le matériau hydrophobe, le précurseur étant ajouté avant la formation de l'émulsion multiple. L'invention se rapporte également à des particules dans lesquelles est intégré un matériau hydrophobe, qui peut être libérable, à des particules dans lesquelles est incorporé un matériau hydrophobe, qui peut être libérable, fabriquées selon le procédé de l'invention, et à des procédés d'utilisation desdites particules.
