Admixtures of cyclic and linear diorganopolysiloxanes, relatively rich in cyclic species, are produced by hydrolyzing a diorganodichlorosilane, in an aqueous hydrochloric acid medium, in the presence of an effective amount of at least one amphoteric surface-active agent, characteristically at least one compound of the formula: <IMAGE> The medium of hydrolysis is facilely separated into an aqueous phase and a cyclic oligomer-enriched siloxane phase essentially devoid of surfactant(s).
