Specific migration of mineral oil (MOSH/POSH and MOAH) into 95% ethanol

Specific migration of mineral oil hydrocarbons (MOH), including mineral oil saturated hydrocarbons (MOSH) with polyolefin oligomeric hydrocarbons (POSH) and mineral oil aromatic hydrocarbons (MOAH) from food contact materials (FCM) into the food simulant D2e (95% ethanol).

The results are reported as the concentrations of groups of MOSH/POSH and MOAH. The groups are formed based on the number of carbons in substances and the reporting unit is mg of MOSH/POSH or MOAH per dm2 of FCM or mg of MOSH/POSH or MOAH per kg of food simulant. Additionally, the result includes the sum amounts of all MOSH/POSH and MOAH together with the total amount of MOH (MOSH + MOAH).

The POSH are not part of MOH but can be present in polyolefin plastics, such as polyethylene (PE) and polypropylene (PP). MOSH and POSH have very similar structures and they tend to elute together in chromatography. Thus in polyolefin plastics and materials with polyolefin layers, it is usually impossible to separate MOSH and POSH with normal analysis techniques.
