A method for hydrolyzing chlorosilanes having at least three chlorine atoms bonded to each silicon atom to form silicone resins is disclosed. The method comprises adding at least one hydridotrichlorosilane, tetrachlorosilane, or organotrichlorosilane to a two-phase mixture containing a non-polar organic solvent, an aqueous phase containing 0 to 43 weight percent hydrochloric acid and a surface active compound represented by the formula
wherein Q is selected from monovalent hydrocarbon radicals, A is selected from the hydrogen atom and alkali metal and n is 0 or 1:
