Abstract
Provided are a production method of liposome dispersion industrially useful and the production equipment.
In a process for forming liposome dispersion by dispersing a membrane material in an aqueous medium, wherein a liquid that the membrane material is dissolved or dispersed is discharged from 161a, while discharging the aqueous medium from 161b, the discharge flows are collectively crushed by a high-speed gas stream from a liquid jet port 162 into minute droplets, then, the droplets are crashed against a flow-blocking body 190 to reaggregate for the production. According to the production of the present invention, since removal of solvent is easy, and there is no need of defoaming operation, it becomes possible to produce liposome dispersion efficiently.
