Process for the preparation of oil-in-water emulsions. |
摘要 |
<p>A process for preparing an oil-in-water emulsion is described, comprising the steps of: adding a mixture of a hydrophobic substance and an emulsifying agent directly or after being dissolved in an organic solvent by heating in a dissolving-emulsifying tank with a high-speed agitation type dispersing means to form a hydrophobic substance solution as an oil phase, introducing waterand/oran aqueous solution of gelatin into the tank through submerged inlet under the hydrophobic substance solution to form a water-in-oil emulsion, and further continuing the addition of water and/or an aqueous solution of gelatin to cause the phase inversion, whereupon the desired oil-in-water emulsion is formed. The mean particle size of the emulsion is decreased more than by the conventional emulsification method, and the particle size distribution is narrowed and made sharp.</p> |
