Abstract

This scientific opinion of the EFSA Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids deals with the safety assessment of the substance 2,4,8,10-tetraoxaspiro[5.5]undecane-3,9-diethanol, β3,β3,β9,β9-tetramethyl- (SPG), CAS No 1455-42-1, FCM No 1052, for use as a co-monomer in polyesters. The polyesters are intended for contact with all food types for long-term storage at room temperature including hot-fill/sterilisation conditions. Migration of the substance into 10 % ethanol was 0.009 mg/kg food and no migration was detected (<0.003 mg/kg food) in 3 % acetic acid. No migration of the oligomers was detectable (< 0.2 mg/kg food). Based on three negative in vitro tests, the Panel considered that the substance does not raise a concern related to genotoxicity, while from a 90-day oral toxicity study in rats not providing a dose-response relationship of the incidental changes, it was concluded that the NOAEL is 2000 mg SPG/kg b.w. per day, the highest dose tested. The substance does not raise concern for accumulation in man. The Panel concluded that the use of the substance 2,4,8,10-tetraoxaspiro[5.5]undecane-3,9-diethanol,β3,β3,β9,β9-tetramethyl- (SPG) as a monomer in the production of polyesters, does not raise a safety concern for the consumer when the migration of the substance itself does not exceed 5 mg/kg food and the migration of the oligomers of less than 1000 Da does not exceed 50 µg/kg food (expressed as SPG).
