In an article published on April 15, 2019, news provider Chemical Watch informed about Japan’s designation of 15 additional substances as priority assessment chemical substances (Pacs) within the Japanese Chemical Substances Control Law (CSCL). Pacs must be assessed as a priority by the government for their hazard and risk to humans and the environment, and companies must submit annual reports when they import or manufacture one metric ton or more of a Pac. This most recent addition brings the total number of Pacs to 223.

The fifteen substances have been listed under their general names along with a non-exhaustive list of CAS numbers representing them. Companies are responsible for determining if substances they work with may belong to the same group of chemicals and would therefore also need to follow the same reporting requirements.

Of the representative CAS numbers provided by the Japanese ministry for these Pacs, the following are included in the FACET inventory of food contact materials:

  • quaternary ammonium compounds, coco alkylethyldimethyl, Et sulfates (CAS 68308-64-5)
  • 1,1′-oxydipropan-2-ol (CAS 110-98-5); oxydipropanol (CAS 25265-71-8)
  • dodecylethyldimethylammonium ethyl sulphate (CAS 3006-13-1); quaternary ammonium compounds, coco alkylethyldimethyl, Et sulfates (CAS 68308-64-5)
  • polyethylene glycol oleyl ether (CAS 9004-98-2); octadecyl polyoxyethylene ether (CAS 9005-00-9)
  • alcohols, C16-18, ethoxylated (CAS 68439-49-6); alcohols, C16-18 and C18-unsatuated, ethoxylated (CAS 68920-66-1); alcohols, tallow, ethoxylated (CAS 61791-28-4)
  • 2-pyridinethiol-1-oxide, sodium salt (CAS 3811-73-2)
