On January 13, 2015 the European Food Safety Authority (EFSA) published two scientific opinions dealing with the safety assessment of new substances for use in food contact materials (FCMs). The first substance, adipic acid dihydrazide (CAS 1071-93-8, FCM substance no. 987) assessed by the Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids (CEF) was approved for use as a crosslinker for acrylic copolymers with keto side groups in laminates made from plastics. The coating shall be used in the inner layers of plastic laminates and is not intended for direct contact with food. Adipic acid dihydrazide is considered neither genotoxic nor does it cause changes in the structure or number of chromosomes. The migration of the substance should not exceed 0.05 mg/kg food. The second substance 1,7-octadiene (CAS 3710-30-3, FCM no. 1034) is considered safe for use as a crosslinking co-monomer in polyolefins at a maximum use level of 0.9%. The substance did not display genotoxicity in three in vitro tests. It can be used for contact with any type of foods for long term storage at room temperature and including hot fill conditions. The migration of the substance shall not exceed 0.05 mg/kg food.
