Neatsfoot Oil is a yellow oil made and refined from bone and shin legs (but not nails) of livestock. "Neat" in the name of oil comes from the ancient English word for livestock. Neatsfoot oil is used as a conditioner, softening and preservative agent for the skin. In the 18th century, it was also used as a topical application for dry scaly skin conditions.
"Prime neatsfoot oil" or "neatsfoot oil compound" is a term used for a mixture of pure neatsfoot oil and non-animal oil, generally minerals or other petroleum-based oils.

Characteristics
Fats from warm-blooded animals usually have high melting points, become hard when cold - but neatsfoot oil remains liquid at room temperature. This is because the legs and legs of relatively lean animals such as cows adapt to tolerate and maintain a lower temperature than the body core, using the current heat exchange at the foot between the warm arteries and the venous veins - other body fat will become stiff at this temperature. This neatsfoot oil characteristic allows it to seep easily into the skin.
Modern neathfood oils are still made from livestock-based products, and are sometimes criticized for the tendency to accelerate the oxidation of the skin. This formulation does not darken the skin, which means that use of light-colored skin tends to change its color. If mineral oil or other petroleum-based materials are added, this product may be called "neatsfoot oil compound". Some brands have also been proven to be fabricated with rapeseed oil, soybean oil, and other oils. The addition of mineral oil can lead to faster decay than non-synthetic sutures or speed breaks from the skin itself.

Producing
After the cattle are slaughtered, the legs and bones of the lower legs, including the skin but not the boiled fingernails. The released oil will be removed, filtered, and pressed. The first emphasis is the highest level, pressing both produces low grade oil and solid press cake or stearin product.
Usage
Neatsfoot oil is used on a number of leather products, although it has been replaced by synthetic products for certain applications. Items such as baseball gloves, saddles, horse harness and other horse nails can be softened and conditioned with neatsfoot oil.
When used on important historic objects, neat oil (such as other leather dressings) can oxidize with time and contribute to embrittling. It can also leave an oily residue that can attract dust. On newer skin, it can lead to embezzlement (even after one application), so it may not be the product you want to use when the lighter color maintenance is desired. Neatsfoot oil is more useful for regular use on work equipment.
Neatsfoot oil is often used for authors' oil-mark brushes that have been used in oil-based paints, since they do not dry up and can be easily washed with solvents at all times. Drying the brush reduces the pigment buildup in the ferrule, the metal parts that many brushes have to hold the hair in place.
Neatsfoot oil of the highest grade is used as a lubricant. It is used in the metalworking industry as a cutting fluid for aluminum. For machining, tapping and aluminum drilling, this is superior to kerosene and a range of water-based cutting solutions. The remaining fat from the second pressing process, solid stearin, is used to make soap.
