LUBRICATING COMPOSITIONS

**Definition:** This place covers:

Lubricating compositions may have three types of essential ingredients: Base materials (main ingredient of the lubricating composition), thickeners (used for preparing grease compositions) and additives.

Additives are those chemicals used to enhance the performance characteristics of the base material where the additives are normally present in a minor amount of a fully formulated lubricating composition, but can be present in a larger amount of an additive concentrate.
