Mineral oils are comprised of various hydrocarbons. If these are aliphatic, i.e. come in the form of saturated linear and cyclic (non-aromatic) hydrocarbons with mostly 16 – 25 carbon atoms, these are referred to as “mineral oil saturated hydrocarbons” (MOSH). Aromatic, i.e. unsaturated hydrocarbons consist of mostly alkylated polycyclic compounds (usually with 1 – 4 aromatic rings) and are referred to as “mineral oil aromatic hydrocarbons" (MOAH).
