A formulation for solidifying used cooking oil or grease and methods of making and using the same is disclosed. The formulation comprises hydrogenated castor oil, sometimes having a flake morphology. In some embodiments, the formulation has a melting point of between 70 and 80° C. and a density between 0.7 and 1.0 g/L. In some embodiments, the formulation is created by heating castor oil in the presence of a catalyst until at least some of the ricinoleic acid content in the castor oil is reduced to form hydrogenated castor oil in a reaction mixture. The method of using the formulation comprises the steps of mixing the formulation and used cooking oil or grease at an elevated temperature until the formulation completely dissolves into the used cooking oil to form a formulation mixture, and waiting until the formulation mixture cools and solidifies prior to disposal.
