• Adds the following CAS numbers and names to Part 3 of the Domestic Substances List:
  • 19431-9 — Amines, polyethylenepoly-, reaction products with succinic anhydride polyalkenyl derivs., non-metal salts
  • 19432-0 — 2,5-Furandione, dihydro-, polyalkenyl derivs., reaction products with polyethylenepolyamine, non-metal salts
  • 19433-1 — Amines, polyethylenepoly-, reaction products with succinic anhydride polyalkenyl derivs., metalloid salts
  • 19552-0 — 1,3-Benzenedicarboxylic acid, polymer with 1,4-benzenedicarboxylic acid, 1,2-ethanediol, 2-ethyl-2-(hydroxymethyl)-1,3-propanediol, hexanedioic acid and methylalkanediol
  • 19553-1 — Alkenoic acid, alkyl-, telomer with butyl 3-mercaptopropanoate, alkyl 2-propenoate, and alkyl 2-alkylpropenoate, ammonium salt
  • 19554-2 — Alkenoic acid, alkyl-, telomer with butyl 3-mercaptopropanoate, alkyl 2-propenoate, and alkyl 2-alkylpropenoate, sodium salt
  • 19560-8 — 2-Propenoic acid, 2-methyl-, polymer with ethyl 2-propenoate, hydroxyalkyl 2-propenoate and methyl 2-methyl-2-propenoate, OO-(1,1-dimethylpropyl) O-(2-ethylhexyl) carbonoperoxoate-initiated, compds. with 2-(dimethylamino)ethanol
  • 19561-9 — 2-Propanol, 1,1’-[(1-methylethylidene)bis(4,1-phenyleneoxy)]bis-, polymer with 1,1’-methylenebis[isocyanatobenzene], alkylene glycol monomethacrylate-blocked
  • 19562-0 — 1,3-Isobenzofurandione, polymer with alkyl(hydroxyalkyl)alkanediol, 1,6-hexanediol and (alkylalkylidene)bis[cyclohexanol]
  • 19563-1 — Oxirane, 2-methyl-, polymer with oxirane, ether with alkyltriol (3:1) and fatty acids
• The order was made by the Minister under the Canadian Environmental Protection Act, 1999 after the required information and assessment period set out in that law had been handled.

Who's affected#

• Companies that make, import or use the listed chemicals in Canada.
• Chemical suppliers, formulators and downstream users (for example, manufacturers that use these substances in products).
• Federal regulators and other organizations tracking the national chemical inventory.
• If it is unclear whether a specific business or product is affected, those businesses should check the exact CAS numbers and substance names against their own inventories.

Why it matters#

• Adding a substance to the Domestic Substances List updates Canada’s official inventory of chemicals.
• That change can influence how the government tracks, assesses and manages those substances under the Canadian Environmental Protection Act, 1999.
• For businesses, it can affect reporting and regulatory planning because the list determines which substances are treated as known (existing) in Canada.
• The order itself simply makes the additions; further regulatory steps or assessments could follow under Canadian law.
