Also disclosed is the use of this lubricating composition for reducing the fuel consumption of a vehicle equipped with a transmission, notably with a bridge or a gear box, lubricated by this lubricating composition.

Natural soap compositions and methods of manufacturing the same having anti-microbial properties for treating and preventing diaper rash and other microbial infections. The soap compositions may contain one or more fatty acids with carbon length ranging from four (C4) to twenty-two (C22) and/or natural fatty acid mixtures of coconut oil, olive oil, and/or tall oil fatty acids which are saponified with lye. The saponification lye may be sodium or potassium hydroxide. In preferred embodiments, the soap compositions contain at least one of sodium or potassium caprate, sodium or potassium caprylate, or mixtures thereof, especially 55:45% caprylate to caprate. The soap compositions are effective at treating or preventing diaper rashes and other microbial infections associated with Candida albicans (Cayeast), Pseudomonas aeruginosa (Psaa Gram negative bacteria), Staphylococcus aureus (Saa Gram positive bacteria), and Aspergillus niger (Ana mold).

The present disclosure concerns a lubricant composition including: at least one base oil; and at least two glycerol esters E.sub.1 and E.sub.2, ester E.sub.1 being an ester of glycerol and of a C.sub.12-C.sub.26 carboxylic acid and ester E.sub.2 being an ester of glycerol and of a C.sub.4-C.sub.10 carboxylic acid. The lubricant composition has good friction properties, and the use thereof promotes fuel savings.

A composition that includes one or more compounds represented by the formula
R.sub.1OR.sub.2
wherein R.sub.1 is a substituted or unsubstituted aryl or polyaryl group having from about 4 to about 40 carbon atoms, and R.sub.2 is a substituted or unsubstituted, linear or branched, alkyl group having from about 4 to about 40 carbon atoms. The composition has a viscosity (Kv.sub.100) from about 1 to about 10 cSt at 100 C. as determined by ASTM D-445, a viscosity index (VI) from about 100 to about 300 as determined by ASTM D-2270, and a Noack volatility of no greater than 50 percent as determined by ASTM D-5800. The disclosure also relates to a process for producing the composition, a lubricating oil base stock and lubricating oil containing the composition, and a method of reducing boundary friction and improving dispersancy of polar additives of a lubricating oil by using as the lubricating oil a formulated oil containing the composition.

The present invention relates to a preparation method of a lube base oil including a conversion of biomass fat to a fatty acid; a separation of a C18 unsaturated fatty acid from the fatty acid; a maximization of an oleic acid content through partial hydrotreating of the C18 unsaturated fatty acid; a synthesis of a dimer or higher-order oligomer through an oligomerization of the oleic acid; and an esterification of the oligomer, and relates to a lube base oil prepared therefrom. The lube base oil of the present invention contains an x-type diester dimer and has an excellent low-temperature stability and a high biodegradability resulting from its chemical structure, thus being ecofriendly.
