Claim:
1. A method of making an oil-in-water microemulsion containing (A) a polysiloxane and (B) a non-volatile inert fluid having viscosity of from 0.65 mPa·s to 10000 mPa·s at 25° C. and selected from a non-volatile inert siloxane fluid and a non-volatile inert organic fluid, where the average emulsion particle size is between 1 and 140 nanometers, said method comprising the steps of: a) preparing an oil phase comprising a polysiloxane containing mixture by the polymerisation of b) optionally quenching the polymerisation; c) optionally mixing one or more surfactants into the oil phase; d) adding water to the oil phase; e) applying agitation or shear to the polysiloxane containing mixture to arrive at an oil-in-water microemulsion; and f) optionally diluting the oil-in-water microemulsion by adding more water.
