Other special remarks are as described in the preceding paragraph (NO). Industrial potential
  • the production method of the present invention it is possible to easily and widely produce a liquid material containing stable microbubbles having a diameter of about 1 Om or less, and as a result, industrial technology, living technology and safety technology can be produced. Many useful or intermediate products are provided in each area.
