Abstract
Abstract A process is provided for preparing semisolid emulsions (creams) wherein a hot oil phase and a cold aqueous phase are mixed under conditions of high shear to interdisperse and homogenize the phases and with a second thereafter cause them to congeal and form a cream. Emulsifiers are included in either or both of the phases or can be separately mixed with the two phases.
