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.

Surfactant composition

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):R&#x2014;O-(AO)&#x2014;C(&#x2550;O)&#x2014;R&#x2003;&#x2003;(I)where Ris Cto Calkyl, 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&#xb0; 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.

Cleaning formulation comprising a solvent additive

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.

Lubricating oils

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):R[(AO)&#x2014;R]&#x2003;&#x2003;(I)wherein Ris 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 Ris independently H or R, where each Ris 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 Rgroups are R. 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.

Lubricant composition comprising hydroxycarboxylic acid derived friction modifier

Provided is a method of dispersing asphaltenes to inhibit asphaltene precipitation and/or deposition in a hydrocarbon. The method includes adding to the hydrocarbon an asphaltene dispersing agent which is an ester of a mono-carboxylic fatty acid and a sugar. The sugar has at least 4 hydroxyl groups. In addition, more than one of the hydroxyl groups on the sugar are reacted with the mono-carboxylic fatty acid to form the ester.

Method and composition for asphaltene dispersion

A method of inhibiting asphaltene precipitation and/or deposition in a hydrocarbon, preferably crude oil, by adding to the hydrocarbon a polyester asphaltene dispersing agent which is the reaction product of an alk(en)yl substituted succinic anhydride wherein the average number of succinic groups per alk(en)yl group is less than 2.0, and at least one polyol.

Asphaltene inhibition

A method of separating oil from a composition containing an oil and water emulsion, by adding a separation additive which is a mixture of a fatty ester of an alkoxylated polyol and 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.

Method of separating oil

A seal swell agent for a lubricating fluid is described. The invention relates to a seal swell agent for use in lubricating oils, such as engine oils, turbine oils, automatic and manual transmission, or gear, fluids, drivetrain and gear oils and hydraulic fluids. The seal swell agent comprises a diester of sorbitol or a derivative thereof and at least one carboxylic acid. The invention extends to the use of a diester of sorbitol or a derivative thereof and at least one carboxylic acid as a seal swell agent, and a method of maintaining seal integrity.

Seal swell additive

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.

A method of separating oil from a liquid stillage is disclosed. The stillage includes an aqueous phase and an oil phase. The method comprises adding a separation additive to the stillage and performing at least one separation operation on the stillage to separate an amount of the oil phase from the stillage. The separation additive comprises an ester of an alkoxylated non-cyclic polyol and a fatty acid.

Method of separating oil from a liquid stillage

A compound of the formulaR.[(AO).A OR]&#x2003;&#x2003;(I)where: Ris the residue of a group having at least m active hydrogen atoms where m is at least 2; AO is an alkylene oxide residue; each n is independently from 0 to 100; and each Ris independently H or an acyl group CORwhere each Ris 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 wherein on average at least 2 of Ris an acyl group. The compounds are particularly suitable for use as emulsifiers and/or dispersants.

Polymeric surfactant

The present invention relates to a process for the manufacture of alkanolamide containing compositions, and more particularly to a process of reacting a fatty acid and diethanolamine (DEA) which result in the formation of low levels of undesirable by products, particularly of bis-hydroxyethyl piperazine (BHEP).
