Table 1

Classification of mineral oil raw materials according to their consistency.

Common INCI name of mineral oil raw materials	Description (considering EC CosIng database)
Mineral oil	Typically used as a general term for derived products from raw oil refinement (often petrolatum).
Paraffinum liquidum	“White mineral oil (petroleum), a highly refined petroleum mineral oil consisting of a complex combination of hydrocarbons.” It mainly consists of saturated hydrocarbons (having carbon numbers in the range of C15–C50).
Hydrogenated mineral oil/distilled petrolatum	The end product of the controlled hydrogenation of hydrocarbons from mineral oil origin.
Paraffin	“A solid mixture of hydrocarbons obtained from petroleum characterized by relatively large crystals.”
Cera microcristallina/microcristalline wax	Hydrocarbon waxes and paraffin waxes of long, branched chain hydrocarbons. Predominantly saturated straight and branched chain hydrocarbons > C35.
Petrolatum	Complex combination of hydrocarbons. It mainly consists of saturated crystalline and liquid hydrocarbons (carbon number predominantly > C25).
Ozokerite	A complex combination of hydrocarbons. It mainly consists of saturated straight chain hydrocarbons (carbon numbers predominantly in the range of C20–C50).
Ceresin	“A complex combination of hydrocarbons produced by the purification of ozokerite.”
