Compositions are disclosed for dewatering mixtures of petroleum and water. The compositions comprise one or more of the following: an unreacted polysaccharide component; and one or both of a polysaccharide component reacted with a hydrophilic component and a polysaccharide component reacted with a hydrophobic component. The compositions may also include viscosifying agents or stabilizers to stabilize the compositions against separation, for example, prior to use. In particularly preferred embodiments the invention is drawn to compositions for breaking an emulsion; such compositions comprising a carbohydrate component containing a cationic starch joined to a hydrophobic moiety, providing the carbohydrate component oil solubility. The composition may optionally comprise one or more additional demulsifier selected from, without limitation, salts (such as a polyaluminum chloride, an aluminum chlorohydrate, an alum, etc.), metal salts (such as iron and zinc salts), dithiocarbamate, tannin, and organic demulsifiers such as poly-DADMAC and similar compounds.

Water-enriching and water depleting compositions and methods

Compositions, such as alkali builder compositions for the laundry industry, are provided and include water, an alkali metal hydroxide component, a chelating component and a hydroxyethyliminodiacetic acid (HEIDA) component. Methods for producing such compositions are also disclosed.

Alkaline composition comprising a chelant mixture, including HEIDA, and method of producing same

A container () for releasing a chemical additive () in a fluid material selected from a lubricant or hydraulic fluid composition comprises a fluid material-impermeable casing () having a hollow interior and an additive composition () comprising at least one fluid material-soluble additive. The additive () is held within the container () by a least one fluid material-permeable element () provided at or near an opening () in the casing () and is effective to provide for release of additive(s) () into the fluid material. Methods of releasing additives () into fluid material are also provided.

Controlled release of additives in fluid systems

A coolant additive composition comprising a sustained release component and an additive component, the additive component is effective to provide at least one benefit to a coolant when released into the coolant, the sustained release component includes a polymeric material and is effective to reduce the rate of release of the additive component into the coolant relative to an identical composition without the sustained release component.

Sustained release coolant additive composition

This invention relates to a fuel filter for use with internal combustion engines. The fuel filter includes a fuel additive that can be released into fuel. The rate of release for the fuel can be controlled. In one form the fuel additive can be mixed with a matrix material and released at a substantially constant rate to maintain a uniform level of fuel additive in the fuel. Use of the present invention provides a fuel filter having an extended life span that is longer than fuel filters typically used with combustion engines.

Fuel filter including slow release additive

A fuel additive composition comprising a sustained release component and an additive component, the additive component is effective to provide at least one benefit to a fuel when released into the fuel, the sustained release component is (1) a polymeric material, (2) substantially insoluble in the fuel, and (3) effective to reduce the rate of release of the additive component into the fuel relative to an identical composition without the sustained release component.

Fuel additive compositions

A container for releasing a chemical additive into a fuel composition comprises a fuel-impermeable casing having a hollow interior and an additive composition comprising at least one fuel soluble additive. The additive is held within the container by at least one fuel-permeable element provided at or near an opening in the casing and is effective to provide for release of additive(s) into the fuel composition. Methods of releasing additives into fuel compositions are also provided.

Controlled release additives in fuel systems

Liquid biodegradable surfactant having oxyethylene and oxypropylene groups attached to the residue of an alcohol having a minimum iodine value of at least 40 wherein the ratio of oxyethylene groups to oxypropylene groups is at least 4:1, and the total moles of oxyethylene and oxypropylene groups is about 9 to about 10 moles per mole of the alcohol.

Liquid biodegradable surfactant and use thereof

A cleaner-inhibitor and method of incorporating same into an automotive or diesel coolant system consisting of 2-4 fluid ounces per gallon of a cleaner whose basic components are:

Automotive cleaner plus inhibitor

A cleaner to be used preferably in conjunction with conventional glycol-type collants in automotive cooling systems and methods of using same. The present cleaners may be referred to as extended-life cleaners which may be added to the glycol coolant and are co-extensive with the life of said glycol. These cleaners operate to dissolve deposits, minimize corrosion damage, and dissolve organic degradation products, all of which cause heat transfer difficulties. The basic cleaner comprises:
