发明名称 Pearlescent capsules and process for their preparation
摘要 Minute capsules having a pearlescent effect are obtained by incorporating inorganic pearlescent particles in the capsule walls during the manufacture thereof. Pearlescent particles of mica coated with titanium dioxide are initially dispersed in an oily internal phase material and then flushed into the aqueous coacervation phase upon addition of the internal phase to an encapsulation medium. The pearlescent particles remain embedded in the capsule wall material and provide the pearlescent effect to the finished capsules.
