A fluid composition comprises A) a branched organopolysiloxane and B) a carrier fluid. Component A) comprises the reaction product of a) a cyclic siloxane and b) a polyorganosiloxane, in the presenceof a hydrosilylation catalyst. Component a) has at least two silicon-bonded alkenyl groups per molecule, and component b) has at least two silicon-bonded hydrogen atoms per molecule. The fluid composition has a viscosity of at least 100 mPa s at 23 degrees and exhibits pituitous rheological properties. The pituitous rheological properties are generally determined from a plot of normal force (in Pascals) vs a perpendicular shear rate in (sec-1). Also disclosed is a personal care composition that comprises the fluid composition. When formulated into a personal care composition, the fluid composition generally provides enhanced sensory and film-forming properties based on its pituitous rheological properties. 本发明公开了种流体组合物，所述流体组合物包含A)支化有机聚硅氧烷和B)载流体。组分A)包括a)环状硅氧烷和b)聚有机硅氧烷在硅氢化催化剂存在下的反应产物。组分a)每分子具有至少两个硅键合烯基基团，并且组分b)每分子具有
