Nanomaterials added to EC approved List of Food Contact Materials

A regulation ‘amending and correcting’ EC Regulation 10/2011 on plastic materials and articles intended to come into contact with food shows that three nanomaterials have been approved for such use. Furthermore another material has been amended to allow for the nanoform of it to be used.

The three materials are:

  • butadiene, ethyl acrylate, methyl methacrylate, and styrene, copolymer cross-linked with divinylbenzene, in nanoform
  • butadiene, ethyl acrylate, methyl methacrylate, and styrene copolymer not cross-linked, in nanoform
  • butadiene, ethyl acrylate, methyl methacrylate, and styrene copolymer cross-linked with 1,3-butanediol dimethacrylate, in nanoform

According to the regulation, ‘the Authority has no safety concern in case those substances are used at a maximum combined weight percentage of 10% w/w in non-plasticised PVC in contact with all food types at ambient temperature or below, including long-term storage, and when used individually or in combination as additives, and when the diameter of the particles is larger than 20nm, and for at least 95% by number the diameter is larger than 40nm’.

The entry for kaolin, on the other hand, has been amended ‘to include particles in the nanoform with a thickness less than 100nm and incorporated up to 12% in EVOH copolymer’. This is because ‘the new specification does not endanger human health if those conditions are met’.

The new regulation, 2015/174, comes into effect on 26 Feb 2015.
