Pituitous silicone fluids

A fluid composition comprising:

• A) 0.1 to 10 wt % of a branched organopolysiloxane prepared by reacting;
• a) an organohydrogencyclosiloxane having the formula [(CH3)HSiO]g where g is 3 to 8, and,
• b) an alkenyl terminated polydiorganosiloxane comprising siloxy units of the formula (R2R2SiO1/2)v(R2SiO2/2)x
• where v≧2, and x≧50,
• R is an alkyl group containing 1 to 6 carbon atoms,
• R2 is an alkenyl group containing 2 to 12 carbon atoms,
• in the presence of a hydrosilylation catalyst, where the molar ratio of alkenyl groups to SiH in the reaction is between 0.9/1 to 2.2/1, and
• B) 90 to 99.9 wt % of a carrier fluid
• selected from isododecane, isohexadecane, or isoparaffin, wherein the fluid composition has a viscosity of at least 300 mPa·s at 23° C. and exhibits pituitous rheological properties.
