Abstract:
A method of producing a branched silicone oil; comprising mixing 100 parts by weight of an organopolysiloxane represented by the following formula (I) and/or an organopolysiloxane represented by the following formula (II) with 0.1 to 100 parts by weight of an organopolysiloxane represented by the following formula (III), and causing the oranopolysiloxanes to undergo condensation and equilibration reactions by heating them in the presence of a basic catalysts: ##STR6##wherein R.sup.1 and R.sup.2 are each a monovalent hydrocarbon group containing 1 to 20 carbon atoms, m is an integer from 3 to 7, and n is an integer of 0 or above; ##STR7##wherein R.sup.3 is a monovalent hydrocarbon group containing 1 to 20 carbon atoms, p is a number from 1 to 100, and q is a number from 0 to 100.
