Abstract: The present invention relates to a method for preparing nanoparticle of active ingredient using lipid as lubricant in milling process, and more specifically, it relates to a method for preparing active ingredient into nanoparticle, which can be properly used in drugs, cosmetics, functional foods, etc., by pulverizing a mixture comprising the active ingredient and a lipid as a lubricant, and a biocompatible polymer having a glass transition temperature of 80° C. or higher by roll mill, and then removing the lipid used as a lubricant therefrom by using supercritical fluid.

Abstract: Disclosed is a non-halogen type highly heat resistant flame retardant epoxy resin composition that is made by compounding a phosphorous-modified epoxy resin with a phosphazene compound as a flame retardant additive, wherein the phosphorous-modified epoxy resin is obtained by reacting a phosphorous-containing compound with an epoxy resin. The non-halogen flame retardant and highly heat resistant phosphorous-modified epoxy resins according to the present invention have the excellent flame retardancy property and the good thermal property without halogen and thus can be advantageously utilized in manufacturing a printed circuit board (PCB) and for complex materials.
