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).

Compositions and devices are provided that provide a persistent low-friction coating on a solid surface, by application of a mixture of a polyethylene glycol-containing surfactant and a vegetable to the surface. The coating thus generated does not require replenishing during use and persists through rinsing and multiple uses. Surprisingly, markedly reduced friction is found when the surfactant is provided at 3% w/v to 7% w/v in the composition. Such compositions and methods are suitable for application to both mixing and separation operations. Formulation of such compositions with food grade components permits use in food processing.

A slide member having a slide surface coated with a lacquer comprising a resin. The lacquer is in turn at least partly coated with a lipophilic composition coating. The lipophilic composition coating provides a slide layer on the slide member with low friction.

Lubrication and friction reduction improves fuel efficiency and reduces energy consumption. Effective and controllable material removal results in superior surface finishing and planarization. Nanosheets are developed with specific functionalization that can be used to reduce friction and wear, improve the fluidic property, and rheological performance

The nanosheets can be from the graphite family, transition metal dichalcogenides, transition metal trichalcogenides, semiconducting chalcogenides, metal oxides, layered hydroxides, clays, ternary transition metal carbides and nitrides, and zirconium phosphates and phosphonates, and their corresponding dopants.

Tribological, rheological, and polishing applications include lubricants, viscosity modification, and chemical-mechanical planarization. The nanosheets are useful in improving efficiency and lifetime of machinery, saving energy for mechanical operations, and optimizing manufacturing processes in surface engineering.

Provided is a grease containing a base oil and a hydrophilic nanofiber, the hydrophilic nanofiber having a thickness (d) of 0.01 to 500 nm being dispersed therein. The grease is low in an environmental load and excellent in safety on the human body and also has an appropriate worked penetration and has a high dropping point, and therefore, it is also excellent in heat resistance.

An improved metal working composition is provided. The composition comprises an additive defined by Formula I:

[R.sup.1(CO).sub.yO(CH.sub.2CHR.sup.2O).sub.z].sub.nPO.sub.4-nX.sub.3-nFormula I

wherein:
R.sup.1 is a saturated or unsaturated, branched or linear, alkyl or aryl hydrocarbon group comprising at least 10 to no more than 24 carbons;
each R.sup.2 is independently selected from H and alkyl of 1-5 carbons;
X is a cation or hydrogen;
y is 0 or 1;
z is an integer of 1 to 20; and
n is 1 or 2.

Compositions having a plurality of hard particles and a plurality of lubricant nanoparticles are disclosed. Methods of making and using the compositions are also disclosed.

A lubricant made by a method of modifying fluid suspended metal sulfide particles that does not require use of hazardous additives. The base oil is derived from a proprietary ester lubricant. The formulation process includes a centrifugation step to remove non-colloidal metal sulfide particles. These non-colloidal particles may be collected and turned into colloidal particles for use in future batches of lubricant.
