    • 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.
    • 公开了一种制备其中具有疏水性材料的颗粒的方法。 该方法包括提供包含分散在疏水介质中的第一乳液的多重乳液,所述第一乳液包含分散在亲水相中的疏水相,其中疏水相包含疏水性材料,亲水相包含能够使 以形成非流体基质并使多元乳液中的前体反应形成其中具有疏水性材料的颗粒形式的基质,其中在形成多重乳液之前加入前体。 还公开了在其中具有疏水性材料的颗粒,其可以是可释放的,以及其中具有疏水性材料的颗粒,其可以是可释放的,通过使用颗粒的方法和方法制备。
