The raw materials commonly used in the production of oleochemicals include RBD palm oil, RBD palm stearin, crude palm kernel oil / coconut oil and tallow.
Oleochemicals are produced by splitting oils or fats through a hydrolysis (using water) or alcoholysis / trans-esterification (using alcohol) process. Hydrolysis produces fatty acids and glycerin while alcoholysis produces fatty acid esters and glycerine.
The other processes involved to further transform fatty acid or fatty acid esters include hydrogenation (conversion of unsaturated fatty acids into saturated fatty acids), distillation (purification) and fractionation (separation of fatty acid by degree of saturation).
