Title:
PRODUCTION OF SEAMLESS CAPSULE PARTICLE CONTAINING SURFACTANT
Document Type and Number:
Japanese Patent JP2784872
Kind Code:
B2
Abstract:
PURPOSE: To obtain capsule particles which are seamless and excel in diffusibili ty and solubility by continuously discharging a coating film forming liquid and a water dispersion body contg. oily components and surfactant components from an outermost nozzle and other nozzles, respectively to form multilayer droplets before hardening or gelatinizing the coating film forming liquid.
CONSTITUTION: After a coating film forming liquid and a water and a water dispersion body contg. oily components and surfactant components are continuously discharged from an outermost nozzle 3 and at least one of other nozzles 1, 2, respectively to form multilayer droplets, the coating film forming liquid of the multilayer droplets is hardened or gelatinized. Consequently, capsule particles having a seamless coating film and contg. the surfactant compounds and the oily compounds are obtained. The capsule particles have desirable appearance, sharp particle distribution and uniform thickness of the coating film and excel in solubility.
