Abstract:
1. 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fed to a high shear mixer in such proportions as to form a viscous oil in water emulsion which is continuously withdrawn from the mixer, wherein the polysiloxane, the surfactant and the water are fed into the high shear mixer through a single supply line and the pressure in the supply line at the inlet to the high shear mixer is monitored to be within 20% of a target pressure in the range of 2 to 20 bar to give a volume-based median particle size in the emulsion in the range of 0.03 to 20 micrometres.
