The invention provides lubricating composition comprising: an oil of lubricating viscosity, and an oxyalkylated hydrocarbyl phenol, wherein the oxyalkylated hydrocarbyl phenol is substituted with at least one aliphatic hydrocarbyl group of 40 to 96 carbon atoms, and wherein the oxyalkylated hydrocarbyl phenol is substantially free of aromatic hydrocarbyl groups. The invention further relates to a method of lubricating a mechanical device (such as an internal combustion engine) with the lubricating composition. The invention further relates to the use of the oxyalkylated hydrocarbyl phenol in the lubricating composition to a passenger car internal combustion engine at least one of (i) control of fuel economy, (ii) control of corrosion, (iii) cleanliness, and (iv) control of bore wear.

A lubricant composition includes at least one branched polyglycerol ether, and more particularly at least one branched polyglycerol ether and at least one dispersant. A method for reducing fuel consumption of a vehicle utilizing a lubricant composition is also provided. Furthermore, a use of a branched polyglycerol ether as a friction modifier in a lubricant composition is disclosed.

Biodegradable pharmaceutical compositions comprising 1,3-propanediol and its esters are provided. The 1,3-propanediol and its esters in the pharmaceutical composition are biologically derived, and as such, the pharmaceutical compositions exhibit a low anthropogenic CO.sub.2 emission profile.

An article having an anti-contamination surface, including a substrate; a first region present on a portion of a surface of the substrate and having a lubricating layer formed thereon; and a second region present on at least a portion of a surface of the substrate other than the first region and having an anti-adhesion coating layer formed thereon; and a method for forming an anti-contamination surface on the surface of an article.

The present invention describes a water based semi-synthetic metal working fluid comprising a base oil, an organic acid, emulsifiers, a concentrate additive, water and a microbial growth control agent which comprises an alky alcohol amine.

Lubricant compositions having at least one base oil composition and a friction-reducing composition comprising at one or more hydrocarbyl aromatics comprising a mono- or poly-functionalized aromatic moiety are described. Methods for making such compounds and methods of drilling using such lubricant compositions are also described.

A composition for cleaning a combustion engine system. The composition comprises a hydrocarbon. The hydrocarbon comprises respective first and second hydrocarbons. The first hydrocarbon comprises a lubricant, wherein the lubricant has a flash point, measured according to ASTM D93, of less than 80 C. The second hydrocarbon comprises an aromatic hydrocarbon, wherein the aromatic hydrocarbon has a flash point, measured according to ASTM D93, of greater than 62 C. The composition further comprises an oxygen donor. The oxygen donor comprises respective first and second oxygen donors. The first oxygen donor comprises a hydroxyl group and has a flash point, measured according to ASTM D93, of from 45 C. to 95 C. The second oxygen donor comprises a carbonyl group or an ether group and has a flash point, measured according to ASTM D93, of from 50 C. to 120 C.

A sump-lubricated, spark-ignited engine is lubricated by supplying thereto a lubricant which comprises (a) an oil of lubricating viscosity; (b) a polyether; and (c) a metal-containing detergent. The lubricant has a total phosphorus content of less than 0.075 percent by weight.

The present disclosure relates to a lubricant composition including at least one base oil and at least one organic compound. The lubricant composition thus makes it possible to reduce, or even to eliminate knock in a vehicle engine, preferably a motor vehicle engine.

Provided are polyalkoxylates that are prepared by alkoxylating polytetrahydrofurane with butylene oxide for use in lubricant compositions and/or for reducing friction in a driveline.
