Abstract: A method of separating oil from a composition containing an oil and water emulsion, by adding a separation additive which is a fatty ester of alkoxylated glycerol, and performing at least one oil separation step. The method is particularly suitable for separating corn oil from stillage produced in a corn ethanol mill.

Abstract: A lubricating composition comprises an amide and at least one additive. The amide is the reaction product of a secondary, branched amine and a carboxylic acid. The carboxylic acid may be a monocarboxylic acid or a dicarboxylic acid, including dimer acid. The amide is hydrolytically stable, and may be used to increase the hydrolytic stability of the lubricant composition. Alternatively, the amide may be used to increase the additive solubility or detergency of the lubricant composition.

Abstract: The present invention relates to a lubricant composition containing a base stock and at least 0.01 wt % of a friction reducing additive which is a compound of the Formula (I): R1[(AO)n—R2]m (I) wherein R1 is the residue of a group having at least 2 active hydrogen atoms; m is at least 2; AO is an alkylene oxide residue; each n is independently from 0 to 100; and each R2 is independently H or R3, where each R3 is independently a residue of a polyhydroxyalkyl or polyhydroxyalkenyl carboxylic acid, a residue of a hydroxyalkyl or hydroxyalkenyl carboxylic acid and/or a residue of an oligomer of the hydroxyalkyl or hydroxyalkenyl carboxylic acid; and on average at least 0.5 of R2 groups are R3. The lubricant composition is suitable for use in an engine oil, a hydraulic oil or fluid, a gear oil and/or a metal-working fluid.

Abstract: A cleaning formulation has from 10 to 99 wt % water, from 0.8 to 40 wt % surfactant, optionally other additives, and from 0.2 to 20 wt % of a solvent additive of formula (I): R1—O-(AO)n—C(═O)—R2 (I) where R1 is C3 to C12 alkyl, AO is an alkylene oxide group selected from an ethylene oxide group, a propylene oxide group and a butylene oxide group. At least one AO group in the solvent additive is an ethylene oxide group. The solvent additive has a water solubility of less than 1 wt % in deionised water at 20° C. and the surfactant enables the solvent additive to dissolve and/or disperse in the cleaning formulation. In a method of cleaning an oily or waxy soil from a hard surface, the solvent additive is applied to the hard surface and optionally rinsed with water. The solvent additive is used in a cleaning formulation to improve the percentage soil removal.

Abstract: A process for making a surfactant composition is disclosed. In the process, a mixture comprising a sugar alcohol and fatty is formed. The mixture contains less than 5% by weight of water based on the total weight of the mixture. The mixture is reacted with an alkylene oxide to make a surfactant composition containing an alkoxylated sugar alcohol fatty acid ester and a polyalkylene glycol fatty acid ester. A surfactant composition and use of the surfactant composition to separate an oil phase and/or an aqueous phase from an emulsion is also disclosed.
