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 (Ca—yeast), Pseudomonas aeruginosa (Psa—a Gram negative bacteria), Staphylococcus aureus (Sa—a Gram positive bacteria), and Aspergillus niger (An—a mold).

A lubricant composition includes a base lubricant and a plurality of lubricant additive molecules. Each lubricant additive molecule includes a surface active group attractable to a target surface, and a carbon containing component connected to the surface active group, for providing a carbon source to form a carbon film on the target surface. A method for in situ forming of a carbon film using the lubricant composition, includes adding the lubricant composition into a target machine such that the lubricant composition is in contact with a target surface of the target machine, and operating the target machine to cause a temperature and a pressure at the target surface so that the carbon containing component is unraveled thereon to form a carbon film on the target surface during the operation.

The present invention relates to a lubricating oil composition containing a base oil (A), a molybdenum dithiocarbamate (B), an ester-based ashless friction modifier (C), and a metal salicylate (D), wherein the content of a molybdenum atom derived from the molybdenum dithiocarbamate (B) is 650 ppm by mass or more on the basis of the whole amount of the lubricating oil composition; a content ratio [C/B.sub.Mo] of the ester-based ashless friction modifier (C) to a molybdenum atom derived from the molybdenum dithiocarbamate (B) is 5.0 to 10 in terms of a mass ratio; the content of a salicylate soap group derived from the metal salicylate (D) is 0.50% by mass or more on the basis of the whole amount of the lubricating oil composition; and a kinematic viscosity at 100° C. is 4.0 mm.sup.2/s or more and less than 9.3 mm.sup.2/s, and a high-temperature high-shear viscosity at 150° C. is 1.7 mPa.Math.s or more and less than 2.9 mPa.Math.s. In accordance with the present invention, a viscosity-reduced lubricating oil composition in which nonetheless a molybdenum dithiocarbamate and an ashless friction modifier are jointly used, not only friction can be reduced early after commencement of lubrication, but also such a state can be maintained, is provided.

A universal additive for fuel and lubricants contains C2-C4 alcohols, carbamide, boric acid, acrylic compounds, and water. The additive allows for more complete combustion of liquid and solid fuels, as well as reduced fuel consumption and fewer harmful emissions. In lubricating oil compositions, the additive reduces wear on the friction surfaces of engines, and also reduces fuel consumption.
