In an article published on January 3, 2017 regulatory news provider Chemical Watch informs that the Canadian government has added three substances to the List of Toxic Substances in Schedule 1 to the Canadian Environmental Protection Act, 1999 (CEPA). The substances are: 1) Hexanedioic acid, bis(2-ethylhexyl) ester (DEHA, CAS 103-23-1); 2) reaction products of 2-propanone with diphenylamine (PREPOD, CAS 68412-48-6); and 3) 1-[[4-(phenylazo)phenyl]azo]-2-naphthalenol (solvent red 23, CAS 85-86-9). “The screening assessments determined that these substances may have harmful effects on the environment or human health,” the Canada Gazette reads. Further, the substances’ “addition to the list will allow the Canadian government to develop regulations to mitigate the risks they may pose,” Chemical Watch writes.

DEHA is included in the Union List of substances authorized for use in plastic FCMs (Annex I of Regulation (EU) No 10/2011), in the FACET inventory of food contact materials (FCMs), as well as in the ESCO working group list of non-plastic FCMs. It is “a plasticizer, widely used in flexible polyvinyl chloride (PVC), such as cling wraps for food packaging,” Chemical Watch explains. PREPOD is also included in the ESCO list. According to Chemical Watch, “solvent red 23 is used as a colorant in oils, fats and waxes; in alcohol-based ester and hydrocarbon solvents; and in polystyrene.” The latter material is used for food packaging.
