A dispersible silicone composition comprising a blend of:

• (I) a silicone composition prepared by reacting at a temperature of 50° C. to 300° C. a mixture comprising:
• (i) 100 parts by weight of at least one polyorganosiloxane selected from
• (A) a polyorganosiloxane having a viscosity of about 20 to 100,000 mm2/s at 25° C. and being expressed by the general formula R1aSiO(4−a)/2 in which R1 is a monovalent hydrocarbon or halogenated hydrocarbon group having 1 to 10 carbon atoms and a has an average value of 1.9 to 2.2,
• (B) a polyorganosiloxane having a viscosity of 200 to about 100 million mm2/s at 25° C. expressed by the general formula R2b(R3O)cSiO(4−b−c)/2 in which R2 is a monovalent hydrocarbon or halogenated hydrocarbon group having 1 to 10 carbon atoms, R3 is hydrogen or a monovalent hydrocarbon group having 1 to 10 carbon atoms, b has an average value of 1.9 to 2.2 and c has a sufficiently large value to give at least one —OR3 group in each molecule, at least one such —OR3 group being present at the end of the molecular chain, or
• (C) a mixture of (A) and (B);
• (ii) 0.5 to 20 parts by weight of at least one silicon compound selected from
• (a) an organosilicon compound of the general formula R4dSiX4−d in which R4 is a monovalent hydrocarbon group having 1 to 5 carbon atoms, X is selected from a halogen atom or a hydrolyzable group and d has an average value of one or less,
• (b) a partially hydrolyzed condensate of said compound (a),
• (c) a siloxane resin comprising (CH3)3SiO½ units and SiO{fraction (4/2)} units wherein the ratio of (CH3)3SiO½ units to SiO{fraction (4/2)} units is 0.4:1 to 1.2:1, or
