PROCESS FOR MICROENCAPSULATION USING OIL-SOLUBLE EMULSIFIERS

摘要

In the process for the preparation of microcapsule dispersions by an interface polyaddition process in which an oil-in-water emulsion is prepared from an oily phase, which comprises the substance to be encapsulated and a lipophilic substance capable of polyaddition, and on aqueous phase, and the reaction partner required for the polyaddition is then added to the aqueous phase, capsules with smaller particle sizes are obtained, with a saving in emulsifying energy, if an oil-soluble emulsifier is added to the oily phase before the emulsification.
