Abstract

A method of preparing droplets wherein a dispersion phase, insoluble or sparingly soluble in water, is injected in the form of a laminar flow into an aqueous continuous phase through an orifice. The viscosity ratio between the two phases is adjusted to a specific range to produce droplets of uniform diameter at a specified jet velocity.
