| Zusammenfassung: | The present invention provides a method for preparing microtubular halloysite nanopowders by cutting halloysite nanotubes at a high pressure, microtubular halloysite nanopowders prepared by the method, and a cosmetic composition comprising the microtubular halloysite nanopowders. According to the method of the present invention, it is possible to prepare the halloysite nanopowders with a tubular shape using natural halloysite and effectively select a halloysite nanopowder having a desired shape. The microtubular halloysite nanopowders can be used in many industrial fields and used as a container or a carrier for nanoparticles or organic materials such as drugs, air fresheners, cosmetics, agricultural chemical materials, etc. |
