Seamless capsule and process for producing the same

Abstract

A seamless capsule comprising a content and a film for coating said content is disclosed. The content is a hydrophilic substance. A viscous liquid having a viscosity of not more than 1000 cp at 100.degree. C. which is scarcely miscible with water is present between the content and the film. There is also disclosed a process for producing a seamless capsule which comprises simultaneously extruding a film solution for the seamless capsule, a hydrophilic substance solution and a viscous liquid which is scarcely miscible with water into a cooling solution from a concentrically arranged multiple nozzle composed of at least three nozzles, an outermost nozzle, an innermost nozzle and at least one intermediate nozzle placed in the middle position between the above nozzles, respectively, the diameter of said nozzle gradually increasing in that order.
