27. A method of preparing a solid formulation comprising a low melting active compound, the method comprising:
-
a) mixing the low melting active compound in particulate form with a free-flow agent in particulate form under high shear or impact to impregnate particles of the low melting active compound with the particles of the free-flow agent to form bound particles of the low melting active compound and the free-flow agent; b) combining the bound particles of the low melting active compound and the free-flow agent with a diluent and one or more formulation adjuvants to form a homogeneous mixture; and c) milling the homogeneous mixture to form particles. - View Dependent Claims (28, 29, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46)

47. A method of preparing a solid formulation comprising a low melting active compound, the method comprising:
-
a) mixing about 10% by weight to about 70% by weight of the low melting active compound in particulate form with about 2% by weight to about 15% by weight of a free-flow agent in particulate form under high shear or impact to impregnate particles of the low melting active compound with the particles of the free-flow agent to form bound particles of the low melting active compound and the free-flow agent; b) combining the bound particles of the low melting active compound and the free-flow agent with about 10% by weight to about 80% by weight of a diluent, about 2% by weight to about 25% by weight of a dispersant, about 1% by weight to about 15% by weight of a binding agent, about 0.1% by weight to about 5% by weight of a pH adjuster, and up to about 5% by weight of a wetting agent to form a homogeneous mixture; c) milling the homogeneous mixture to form particles; and d) further processing the particles with up to about 5% by weight of an anti-foam agent to be in a solid delivery form; wherein all of the percentages are based on the final weight of the overall solid formulation.
