Abstract

In a process for the production of a silicone in water emulsion in which a polysiloxane fluid, at least one surfactant and water are continuously fed to a high shear mixer in such proportions as to form a viscous oil in water emulsion which is continuously withdrawn from the mixer. The polysiloxane fluid may be a non-reactive fluid or may have reactive groups capable of taking part in a chain extension reaction. A desired emulsion particle size can be maintained by monitoring the pressure in the supply line at the inlet to the high shear mixer.
