A common source is present in some mineral oils. When operating at low tempera- tures (0 to 30 degrees F), waxes existing in these lubricants may precipitate. Water contamination can also intensify this effect. Other precipitations may be produced by a variety of causes such as cross-contamina- tion of different lubricants (including synthetics), the use of assembly oils, employing certain types of additives or even contaminants from the environment. In order to determine the root cause of the waxy material, you may wish to analyze it using Fourier transform infrared (FTIR) or X-ray fluorescence (XRF) spectroscopy and identify its properties. This information along with the machine's maintenance/ operation history can help you pinpoint the origin. Also, you can filter the oil for patch tests and observe it under a microscope. Regardless of the waxy material's origin, there are ways to help prevent it. You should try to minimize cross-contamination among lubricants, assembly oils and additives used in the machine. Take steps to control contaminants in the oil that come from the environment or production processes. Before using an additive or assembly oil, or switching to a synthetic lubricant, ask the lubricant supplier about the potential effects of mixing different products. Also, be sure to limit lubricant contamination with water or process emulsions. In addition, if the equipment must work at low temperatures, verify that the lubri- cant formulation is appropriate for these operating conditions. Most likely the waxy residue did not come from a sealant. When a seal or gasket is incompatible with a lubricant, the typical effects are gasket swelling or shrinking but not the generation of wax products.

Mineral oils are highly flammable and are a serious source of fire hazard in high temperature environments and applications close to open flames or red-hot metal parts. The risk is further increased by the rapid and aggressive ignition rate of mineral oils which can cause disruption in production, plant shutdown, increased insurance premiums, and threats to worker safety.
