Abstract
The invention provides an emulsification technique which permits the formation of functional oil/water or functional granules/water emulsion systems excellent in thermal stability and long-term stability and which can attain the emulsification independent of required HLB of the functional oils, and the dispersion independent of surface properties of the functional granules. In the technique is used an emulsifying dispersant comprising, as the main component, vesicles formed from an amphiphilic substance capable of self-assembly or an emulsifying dispersant comprising single particles of a biopolymer as the main component. The particles made from amphiphilic substances capable of self-assembly are used. The amphiphilic substances are selected from among polyoxyethylene-hydrogenated castor oil derivatives represented by the general formula (1) wherein the average number of added ethylene oxide molecule is 5 to 15, dialkyldimethyl-ammonium halides wherein the chain length of the alkyl or alkenyl is 8 to 22, and phospholipids or phospholipid derivatives. According to the invention a three-phase structure composed of an aqueous phase, an emulsifying dispersant phase and an oil phase is …
