A wear-indicating metalworking fluid is provided that includes a lubricant base; and a wear-indicating agent. A method of determining wear in a metalworking fluid includes providing wear-indicating metalworking fluid that contains a lubricant base and a wear indicating agent; and observing the visual appearance of the metalworking fluid. A change in visual appearance of the metalworking fluid when compared to an unused metalworking fluid indicates wear of the metalworking fluid.

A composition for an aqueous tacky lubricant, specifically targeted towards increasing lubricant retention to the moving components of chainsaws. More specifically, the composition includes a novel additive composition for environmentally-neutral lubricants. The ideal function of the composition would be to increase the adhesive qualities of an aqueous lubricant without compromising the coolant and lubricant roles of such a substance. To accomplish this, the composition includes an additive compound, that is made of a linear anionic polyamide and a cationic surfactant. The reaction between the linear anionic polyamide and the cationic surfactant creates a viscoelastic tackifier that helps the lubricant to cling to a moving chain thus preventing the lubricant from flinging off the chain when in motion. In other words, the additive compound is a tackifier agent, presented as novel both as an independent composition and in addition to extant lubricants.

This process involves combining ethanol with a polymer-based composition, characterized in that the polymer is obtained from at least 50 mol % of at least one monomer selected from the group comprising N-substituted acrylamides, N-substituted methacrylamides, N,N-substituted acrylamides, N,N-substituted methacrylamides, substituted acrylates and substituted methacrylates.

A method and composition for reducing a coefficient of friction are disclosed. In an embodiment, a method for reducing a coefficient of friction between two surfaces in a borehole includes preparing a mixture comprising a primary lubricating agent, a primary surfactant, a spreading agent, and an aqueous fluid. The method also includes pumping the mixture into the borehole such that the mixture contacts the two surfaces and reduces the coefficient of friction for the two surfaces.

Drilling fluid compositions and methods for using drilling fluid compositions are provided with enhanced anti-bit balling properties that include an aqueous-based fluid, one or more drilling fluid additives, and an anti-bit balling additive.
