New Chemicals Added to Domestic Substances List

Summary#

This is Order 2023-87-10-01 Amending the Domestic Substances List under the Canadian Environmental Protection Act, 1999. It adds several chemical substances to the federal Domestic Substances List; the Order was registered on November 8, 2023 and published in the Canada Gazette on November 22, 2023.

What it does#

• Adds four entries to Part 1 of the Domestic Substances List: 403641-53-2, 1215267-86-9, 2020004-19-5, 2566495-55-2.
• Adds several entries to Part 3 of the Domestic Substances List, including:
  • 14211-0 — 2‑Propenoic acid, 2‑methyl‑, polymer with alkyl 2‑propenoate and ethene, magnesium salt
  • 19679-7 — Alkanoic acid, 3‑oxo‑, 2‑[(alkyl‑oxo‑propenyl)oxy]ethyl ester, polymer with alkyl 2‑propenoate and alkyl 2‑alkyl‑2‑propenoate
  • 19680-8 — Fatty acids, C18‑unsatd., dimers, hydrogenated, polymers with 2‑oxoheteromonocycle and polyalkylolalkane
  • 19685-3 — Carboxylic acids, di‑, C10‑14, polymers with acrylic acid, Bu acrylate, alkanediols, 2‑ethylhexyl acrylate and styrene, tert‑Bu peroxide‑initiated
• The Order took effect on the registration day (November 8, 2023).

Who's affected#

• Companies that make, import, or use the listed chemicals in Canada.
• Chemical suppliers, formulators, and downstream users in industries like polymers, coatings, lubricants, personal care, or other industrial applications (depending on the substance).
• Federal regulators and anyone tracking which chemicals are known to be in Canadian commerce.

If it is unclear whether a specific business or product uses one of these chemical entries, the business will need to check the exact CAS numbers and chemical names.

Why it matters#

• Being on the Domestic Substances List means these substances are recognized as present in Canada. That affects how Environment Canada and Health Canada track and assess them.
• For companies, listing can change what reporting or information requests they might receive from regulators in future risk assessments or compliance checks.
• For the public, it signals which chemicals are in use domestically and can be a step toward further study or management if health or environmental concerns arise.
