Document Type and Number:
WIPO Patent Application WO/2019/009335
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing: a method for dry-coating surfaces of nucleic substances having particle diameters of 100 μm or less, said nucleic substances being used as primary particles; and fine particles which are produced by this method. The present invention provides a method for producing particles that are covered with a resin or a fat/oil, which comprises a step for mechanically mixing first particles that contain an active component and have particle diameters of 100 μm or less and second particles that contain at least one of a resin and a fat/oil.
