The process is called saponification, with which you make soap.
When oil is mixed with an alkali, it forms glycerin and a sodium salt of fatty acid.
Soap
Sodium and Potassium are often store in oils or air sealed containers so they dont react with humidity.
fingerprints can be visible by dusting the print using a special powder and brush. the oils from the fingerprint react with the power and become visible.

Lipids (wax, fats and oils)
The term density has the same meaning when applied to motor oil that it has in any other context. It means weight divided by volume, or in other words, for a given volume of substance, how heavy is it? ---------------------------------------------------------------- Density of liquids is often compared to that of water. Motor oils, have various densities based upon the additives used in them as well as whether they are synthetic or mineral oils. You will find the densities of different oils will typically fall between 0.72 and 0.87 specific gravity at 60 degrees F compared to water at 60 degrees F. As oils (and water) are heated (or cooled) their densities change accordingly. Some oils are actually heavier than water and will sink, but these are usually special types.
Soap
Alkali react with greases and oils forming water soluble soaps.
Sugars; as well as lipids - (both fats and oils).
Gasoline is considered to be a substance. It is not a mixture because it cannot be separated in a non-chemical process.
oils are insoluble in water
Soap is a product of reaction of fatty acids (present in vegetable oils and fats) and strong alkalis (NaOH or KOH). No alkali should be present in the final product - soap. If it is, this means that more alkali was used than necessary for saponification and the excess was not separated in the additional steps.
Minerals
oils are insoluble in water
oils it secretes sebum which is an oily or waxy substance which keeps the skin and hair moisturized
rocks minerals oils and sand, any more?
Oils and fats for soap are compounds of glycerin and a fatty acid. When oils are mixed with an alkali, they form glycerin and the sodium salt of the fatty acid. The fatty acids required for soap making are supplied by tallow, grease, fish oils, and vegetable oils. The hardness, lathering qualities, and transparency of soap vary according to the combinations of fats and alkalis used as ingredients. An experienced soap crafter uses many combinations of oils.
