Five Chemicals Added to Domestic Substances List

Summary#

Order 2025-87-06-01 Amending the Domestic Substances List (SOR/2025-170) adds five chemical entries to Canada’s Domestic Substances List. The Order was registered on August 29, 2025 and published in the Canada Gazette on September 10, 2025. The Minister of the Environment, Julie Dabrusin, made the Order under the Canadian Environmental Protection Act, 1999.

What it does#

• Adds three entries to Part 1 of the Domestic Substances List:
  • 14802-03-0 — marked N
  • 1204391-75-2 — marked N-P
  • 1884382-74-4 — marked N-P
• Adds two entries to Part 3 of the Domestic Substances List:
  • 19772-0 — 2-Propenoic acid, 2-methyl-, 2-hydroxyethyl ester, polymer with ethenylbenzene, 2-hydroxyethyl alkenoate, methyl 2-methyl-2-propenoate and 2-methylpropyl 2-methyl-2-propenoate, bis(1,1-dimethylpropyl) peroxide-initiated (marked N-P)
  • 19773-1 — Plant-based oil, maleated, mixed esters with lauryl alc. and polyethylene glycol mono-Me ether (marked N-P)
• States the Order “comes into force on the day on which it is registered” (so its legal effect began on August 29, 2025).
• A Regulatory Impact Analysis Statement related to this Order appears alongside SOR/2025-171.

Who's affected#

• Companies that make, import, sell or use the listed chemicals in Canada.
• Laboratories, suppliers, and downstream users who track chemical inventories.
• Government regulators and analysts who manage Canada’s chemical inventory under the Canadian Environmental Protection Act, 1999.
• If it’s unclear whether a specific business or product is affected, those businesses should check the chemical CAS numbers and names against their own records.

Why it matters#

• Being added to the Domestic Substances List means these substances are formally recorded on Canada’s inventory of existing domestic chemicals.
• That listing can influence reporting, monitoring, and any future testing or regulatory decisions about the substances.
• Businesses that handle these chemicals may need to review their compliance, record-keeping, and reporting practices in light of the additions.
