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.

The present invention provides a coalescing agent for aqueous coatings, a coalescing agent composition, and an aqueous coating. The coalescing agent for aqueous coatings is obtained by esterification reaction of fatty acids and glycol ethers. The coalescing agent prepared by the present invention has a boiling point as high as 330° C., has no irritant odor, and is environmental friendly and safe. It overcomes shortcomings of conventional coalescing agents, which is suitable for various polymer emulsion systems, and can significantly reduce the film-forming temperature of aqueous emulsion coatings and optimize the film-forming performance.

The present invention describes a process for obtaining a biolubricant from vegetable oil, which comprises the steps of (a) esterification reaction of the product of vegetable oil hydrolysis using a branched aliphatic alcohol; (b) epoxidation reaction of the esters obtained in step (a); and (c) nucleophilic substitution reaction of the epoxidated esters obtained in step (b) using a branched aliphatic alcohol. The present invention also describes a biolubricant obtained from the process. More specifically, a biolubricant is described that is produced from a ricinoleic fatty acid, whose formula is illustrated in FIG. 1 of the present invention, and where R.sub.1 is a hydroxyl or it is from the formula R.sub.3COO.sup.−, with R.sub.3 being an alkyl radical C.sub.1-C.sub.3, preferably a methyl radical; and R.sub.2 consists of a straight chain of hydrocarbons C.sub.4-C.sub.8 and a branched chain of hydrocarbons C.sub.1-C.sub.3.
