Applications / MOSH/MOAH


What is MOSH/MOAH?

MOSH (Mineral Oil Saturated Hydrocarbon), chain and ring-shaped.
MOAH (Mineral Oil Aromatic Hydrocarbon), predominately alkylated polycyclic.

MOSH and MOAH are mineral oils commonly used in industrial inks, notably used for printing newspapers.  Since newspapers form a significant part of the paper/carton recycling stream, recycled paperboard often contains a mixture of MOSH and MOAH.  

A potential health hazard if ingested, regulations exist concerning the migration of MOSH into foodstuffs. Although not yet directly regulated, MOAH typically contains components that are known to be carcinogens.

A hidden health concern in recycled paperboard

Paperboard used for food packaging is commonly made of recycled paper products.  The concern is that residual mineral oil inks in the recyclate may migrate into food, either from the carton box itself or from the outer carton box used for shipping.  

Using virgin paperboard for food packaging is a temporary solution, but supplies are limited. Furthermore, it does not solve the possibility of MOSH/MOAH migration from the outer carton boxes used for distribution.
