    • The present invention relates to an anhydrous liquid composition wherein monoglyceride is mixed with an emulsifier and a solvent, and the manufacturing method thereof, and more specifically, to an anhydrous liquid composition wherein monoglyceride is mixed with a water-insoluble material, an emulsifier and a solvent, and the manufacturing method thereof. Further, the present invention relates to a lyophilized powder and the manufacturing method thereof, wherein the lyophilized powder is prepared by dissolving the mixed liquid composition in water, adding with a cryoprotectant followed by the lyophilization. In the process of dispersion, the lyophilized liquid composition and the powder of the present invention can spontaneously generate particles of 200-500 nm by gently shaking with hands without a powerful mechanical force. Also the lyophilized liquid composition and the powder of the present invention are physicochemically stable since they neither contain water that causes oxidation or hydrolysis upon storage nor undergo phase separation. Considering all the raw materials of the present invention are biocompatible, the present invention will be useful in medical and pharmaceutical fields such as drug delivery.
    • 本发明涉及将单酸甘油酯与乳化剂和溶剂混合的无水液体组合物及其制造方法,更具体地,涉及将单酸甘油酯与水不溶性物质,乳化剂和 溶剂及其制造方法。 另外,本发明还涉及一种冻干粉末及其制造方法,其特征在于,所述冻干粉末是将所述混合液体组合物溶解在水中,加入冷冻保护剂后进行冻干。 在分散过程中,本发明的冻干液体组合物和粉末可以通过用手轻轻晃动而自发产生200-500nm的颗粒,而没有强大的机械力。 此外,冻干液体组合物和本发明的粉末在物理化学上是稳定的,因为它们既不含有在储存时引起氧化或水解的水也不经历相分离。 考虑到本发明的所有原料都是生物相容的,本发明可用于医药领域如药物递送。
