The invention concerns a method for emulsifying, without grinding, a silicone in water in the presence of a surfactant, at a temperature less than 60° C. and under shearing at less than 100 s−, comprising steps which consist in: a) preparing a primary oil-in-water emulsion including said surfactant and said silicone under shearing at less than 100 s−, by adding an aqueous phase to an oily phase comprising said silicone; b) enriching the resulting emulsion with an enriching oily phase comprising said silicone by mixing, under shearing at less than 100 s−, and c) if required, repeating one or several times the operation at step b) until the desired concentration in surfactant and/or silicone in the final emulsion is obtained and/or until the desired particle size distribution is obtained.
