The present invention describes tunable methods of treating cellulosic materials with a composition that provides increased hydrophobicity and/or lipophobicity to such materials without sacrificing the biodegradability thereof. The methods as disclosed provide for binding of saccharide fatty acid esters on cellulosic materials, including that the disclosure provides products made by such methods. The materials thus treated display higher hydrophobicity, lipophobicity, barrier function, and mechanical properties, and may be used in any application where such features are desired.

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.
