An article Migration from acrylonitrile butadiene styrene (ABS) polymer: swelling effect of food simulants compared to real foods WOS:000604175100002 published article about POLYETHYLENE TEREPHTHALATE; MONOMER; POLYSTYRENE in [Guazzotti, Valeria; Ebert, Annika; Gruner, Anita; Welle, Frank] Fraunhofer Inst Proc Engn & Packaging, IVV, Giggenhauser Str 35, D-85354 Freising Weihenstephan, Germany in 2021.0, Cited 21.0. The Name is Benzophenone. Through research, I have a further understanding and discovery of 119-61-9. Formula: C13H10O
Materials and articles made of acrylonitrile-butadiene-styrene (ABS) intended for contact with food must comply with the requirements of the European Plastic Regulation (EU) 10/2011, which lays down the food simulants and the time/temperature conditions to be applied for migration testing. Previous studies indicated that high concentrations of ethanol at temperatures above ambient may lead to swelling of ABS polymers resulting in increased migration. In this study migration kinetic data for a set of model substances at different temperatures were obtained using both food simulants stipulated in EU regulations and real food (milk, cream and olive oil). At the same time, the extent of polymer swelling was gravimetrically characterized after contact with simulants and different foods tested at several conditions to cover the majority of foreseeable applications of ABS. The obtained results confirmed that the use of high concentrations of ethanol-water, especially at high temperatures, causes the swelling of ABS polymers and results in significantly higher migration values compared to the tested foods as well as Tenax(R). None of the real foods studied cause significant swelling of ABS. The widely used simulant 95% (v/v) aqueous ethanol proves not be suitable for compliance testing of ABS under the recommended conditions of Regulation (EU) 10/2011. Swelling of the polymer results in artificially higher diffusion coefficients or lower activation energies of diffusion. Migration prediction using polymer-specific diffusion parameters should therefore be considered to avoid over-conservative risk assessment for food contact materials and articles made of ABS.
