Method for preparing nano particles

摘要

The present invention relates to a method for manufacturing nano-scale particles of an active material. More particularly, the present invention relates to a method which uniformly mixes a surfactant having an HLB value of 8 or more and a melting point or glass transition temperature of 80° C. or lower and an active material, and mills the mixture using a roller mill, to thereby prepare nanoparticle powder from the active material.

主权项

1. A method for preparing nanoparticle powder of an active ingredient, comprising:
(1) uniformly mixing an active ingredient with a surfactant having an HLB value of 8 or more and a melting point or a glass transition temperature of 80° C. or lower; and (2) grinding the mixture obtained in step (1) by using a roller mill, wherein water is added to the mixture in step (1) or step (2) and the amount of water is 1% to 5% by weight, based on the total weight of the mixture obtained in step (1).
