Abstract: An encapsulated particle includes a core particle, a polyurethane layer, and a wax. The polyurethane layer is disposed about the core particle and the wax is disposed about the polyurethane layer. The polyurethane layer includes the reaction product of an isocyanate and a polyol component. The polyol component includes a catalytic polyol derived from an aromatic amine-based initiator and a polyether polyol that is different from the catalytic polyol in a weight ratio of from about 1:2 to about 10:1. A method of encapsulating the core particle includes the steps of providing the core particle, the isocyanate, the polyol component, and the wax. The method also includes the steps of mixing and reacting the isocyanate and the polyol component to form a polyurethane, encapsulating the core particle with the polyurethane layer which comprises the polyurethane, and encapsulating the polyurethane layer with the wax.

The polyurethane layer is disposed about the core particle and includes the reaction product of an isocyanate and a polyol component. The polyurethane layer is formed in the presence of a silicone surfactant. The polyol component includes a first polyol having a nominal functionality of at least 2.5 and a hydroxyl number of from 20 to 300 mg KOH/g. A method of encapsulating the core particle includes the steps of providing the core particle, the silicone surfactant, the isocyanate, and the polyol component. The method also includes the steps of mixing the isocyanate and the polyol component and encapsulating the core particle with the polyurethane layer.
