Abstract (en)
An emulsifier in which the particle size of an emulsion or a suspension can be continuously adjusted, has a rotor (3) that is rotated by a motor (5) and a stator (4). It produces an emulsification action by shear force with said rotor, and the device is characterized by having an apparatus (6) for modulating the frequency of the input current to the motor in order to vary the rotational speed of the rotor. The corresponding methods for manufacturing either an emulsion of a silicone oil by emulsifying a silicone oil, an emulsifying agent, and water, or a suspension of crosslinked silicone particles by emulsifying a liquid crosslinkable silicone composition, an emulsifying agent, and water, are characterized by preparation of the emulsion or the suspension in an emulsifier in which the particle size of the emulsion or suspension is adjusted by varying the rotational speed of the rotor. <IMAGE>
