<p>An object of the present invention is to provide a method for producing a composition having a disperse phase finely dispersed in a continuous phase with low polydispersity, the method which is excellent in production efficiency This object is achieved by a method for producing a composition having a disperse phase finely dispersed in a continuous phase, the method comprising the steps of: (A) supplying a swirl flow of a continuous phase liquid into a cylinder having a circumferential surface partially or wholly composed of a porous membrane; (B1) jetting a disperse phase fluid through the porous membrane into the swirl flow to form a fluid column extending from a surface of the porous membrane into the cylinder; and (B2) by means of a shear force of the swirl flow, cutting off a part of the fluid column at a position with a distance of 2P to 10P in a radial direction from the surface of the porous membrane, where P is an average pore size of the porous membrane.</p> |
