Oleochemicals can be made from the components of renewable animal, marine and vegetable oils and fats. This oleochemical group of products is a large one, comprising fatty acids, glycerol and numerous derivatives of these including fatty alcohols, fatty esters, and nitrogen‐, phosphorus‐and sulphur‐containing materials. Polyoxyalkylated end products from the above, from heavy metal and water‐soluble soaps, epoxidised chemicals, polymer components, and the quarternary ammonium compounds are found. The oleochemicals of interest to the lubricants manufacturer are those which function in some specific manner. Anti‐corrosive, anti‐oxidant, anti‐squawk, anti‐stick, anti‐sludge, anti‐wear detergent, dispersant and oiliness agents, pour point depressants and viscosity modifying materials, are examples.
