In which, the nanoparticles are CuO. The coffee biofuel is extracted from coffee dregs and has a viscosity of 60 to 70 cSt at a temperature of 40 degrees Celsius. It can reduce the friction coefficient and operating temperature. In addition, it can replace the mineral oil.

The present invention relates to conveyor lubricant compositions including an emulsion of a lipophilic compound and also including an emulsifier and/or an anionic surfactant. The present invention also relates to methods employing such lubricant compositions. In an embodiment, the method includes applying the present lubricant composition to a conveyor with a non-energized nozzle.

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.
