Liposome composition using sugar alcohol with modified surface area and/or porosity as carrier and method for preparing same

Abstract

The present disclosure relates to a method for preparing a novel sugar alcohol with a modified, that is, increased or decreased surface area and/or porosity while having flowability as a solid phase, and also to a sugar alcohol prepared by the preparing method or a pharmaceutical composition, a cosmetic composition, a food composition and a feed composition, comprising the sugar alcohol as a carrier. According to the present disclosure, the method for preparing a sugar alcohol comprises: (A) reacting the sugar alcohol in a solid state with a solvent (S), wherein the solid state sugar alcohol is not dissolved by the solvent (S) and is reacted with the solvent (S) as a solid dispersion; and (B) removing the solvent (S) therefrom. The sugar alcohol prepared by the preparing method of the present disclosure has a modified, that is, increased or decreased surface area and/or porosity in comparison with a conventional sugar alcohol. When the sugar alcohol prepared by the preparing method of the present disclosure is used as a carrier, a coating object, etc., or as a component of compositions for drugs, food, cosmetics, feed, etc., a ratio of an active ingredient to the carrier can be modified, so that the sugar alcohol can be used in preparing of formulations or compositions.
