Abstract

A method of producing finely divided, stable oil-in-water emulsions of organopolysiloxanes is disclosed. The condensation and/or polymerization of lower molecular organosilicon compounds is carried out in a paste which consists of the organosilicon compounds, the amount of emulsifier required for preparing the emulsion and an amount of water equal to 0.5 to 3 times the weight of the emulsifier. This transparent to weakly opaque paste is then stirred in water in order to form an emulsion.
