Additive that promotes the formation of a stable mixture, or emulsion, of oil and water. Common emulsifiers are: metallic soaps, certain animal and vegetable oils, and various polar compounds.

Related Terms

ALKALINE BOIL-OUT

Employed to remove oil and grease deposits from heating surfaces.

BULK CARGO

Cargo such as oil, coal, ore, woodchips, etc. not shipped in bags or containers

ANTISTATIC ADDITIVE

An additive that increases the conductivity of a hydrocarbon fuel to hasten the dissipation of electrostatic charges during high-speed dispensing, thereby reducing the fire/ explosion hazard.

DETERGENT

In lubrication, either an additive or a compounded lubricant having the property of keeping insoluble matter in suspension thus preventing its deposition where it would be harmful. A detergent may also redisperse deposits already formed.

OILING SPLASH SYSTEM

Method of lubricating moving parts by agitating or splashing oil in the crankcase.

CLOUD POINT

The temperature at which waxy crystals in an oil or fuel form a cloudy appearance.

CORROSION INHIBITOR

Additive for protecting lubricated metal surfaces against chemical attack by water or other contaminants. There are several types of corrosion inhibitors. Polar compounds wet the metal surface preferentially, protecting it with a film of oil. Other compounds may absorb water by incorporating it in a water-in-oil emulsion so that only the oil touches the metal surface. Another type of corrosion inhibitor combines chemically with the metal to present a non- reactive surface.
