A method for the mechanical preparation of an oil-in-water microemulsion containing an inert fluid selected from (A) polysiloxane and (B) inert siloxane fluid and inert organic fluid is provided, wherein said average emulsion particle size is 1 to 140 nm. The process comprises the steps of: i) polymerizing the silane or siloxane containing monomers and / or oligomers in the presence of an inert fluid, a suitable catalyst and optionally an end-blocker to produce an oil phase comprising the polysiloxane containing mixture, ii) as necessary Quenching the polymerization process, wherein the inert fluid is substantially maintained in the obtained polysiloxane-containing mixture, i) mixing one or more surfactants in the oil phase, if necessary, i) water in the oil phase After the addition, stirring or shearing the mixture to produce an oil-in-water microemulsion, i) optionally further adding water to the oil-in-water microemulsion and diluting. |
