Specific migration of vinyl acetate [CAS: 108-05-4] from a sample or material intended for food contact. Vinyl acetate is listed with FCM 231 and Ref No. 10120 in European Commission Regulation No 10/2011 with an SML value of 12 mg/kg of food.

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 a food simulant. Analysis is possible with food simulants 10%, 20%, 50%, and 95% ethanol, 3% acetic acid, iso-octane, olive oil, and Tenax. The price includes testing with one simulant. The results are reported as the concentrations of fractions of MOSH/POSH and MOAH, with grouping based on the number of carbon atoms in the substances. The reported fractions are listed in the table below: MOSH/POSH (C10-C50), total MOAH (C10-C50), total MOSH/POSH (≥C10-≤C16) MOAH (≥C10-≤C16) MOSH/POSH (>C16-≤C20) MOAH (>C16-≤C25) MOSH/POSH (>C20-≤C25) MOAH (>C25-≤C35) MOSH/POSH (>C25-≤C35) MOAH (>C35-≤C50) MOSH/POSH (>C35-≤C40) MOSH/POSH (>C40-≤C50) 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. The analysis includes a compliance assessment according to the following references: MOSH fraction: in-house risk assessment POSH fraction: Plastics Europe documentation Polyolefin oligomers: research project for risk assessment. MOAH fraction: Standing Committee on Plants, Animals, Food and Feed Section Novel Food and Toxicological Safety of the Food Chain 19 October 2022

Specific migration of oligomers of poly((R)-3-hydroxybutyrate-co-(R)-3-hydroxyhexanoate) (PHBH, CAS 147398-31-0) from a plastic food contact material. The compound is listed under FCM 1059 in Annex I of European Regulation No 2011/10. The specific migration limit (SML) of 5 mg/kg is applied to all PHBH oligomers with molecular weight below 1,000 Dalton.

Specific migration of acrylonitrile [CAS: 107-13-1] from a plastic food contact material. The substance is listed as FCM 225 with Ref No. 12100 in European Commission Regulation No 2011/10. According to the regulation, there must be no detectable migration of acrylonitrile to food with a 0.01 mg/kg detection limit.

Specific migration of hexamethylene diisocyanate [CAS: 822-06-0] from a sample or material intended for food contact. The substance is listed under FCM 372 and Ref No. 18640 in European Commission Regulation No 10/2011 on plastic food contact materials. The specific migration limit (SML) of hexamethylene diisocyanate is ND (not detected), which means migration must not be observed with a 0.01 mg/kg detection limit. Note that we also offer an isocyanate testing package for measuring the residual content of hexamethylene diisocyanate and three additional isocyanates.
