Short chain saturated hydrocarbons (MOSH) are easily absorbed by the human body and can be stored in several organs. Animal studies have shown that such mineral oil mixtures can lead to accumulations and damage in the liver and lymph nodes. The exact composition of chemical mixtures in printing inks, especially those that contain aromatic hydrocarbon compounds (MOAH), is unknown. The complex mixtures primarily consisting of alkylated aromatic hydrocarbons, to which MOAH also belong, also could include carcinogenic substances.
