Adds chemicals to Domestic Substances List

Summary#

Order 2022-87-09-01 Amending the Domestic Substances List adds several chemicals to Canada’s inventory of existing substances under the Canadian Environmental Protection Act, 1999. The order was registered on October 4, 2022 and published in the Canada Gazette on October 26, 2022.

What it does#

• Adds the following CAS numbers to Part 1 of the Domestic Substances List:
  • 24748-23-0
  • 26813-83-2
  • 81901-62-4
  • 107087-28-5
  • 780769-22-4
  • 1042950-30-0
  • 1259992-48-7
  • 1803088-15-4
• Adds the following entries to Part 3 of the Domestic Substances List (these include chemical names):
  • 19613-1 N — Alkanoic acid, 2,2,6,6-tetramethyl-4-piperidinyl ester, reaction products with oxidized polyethylene and 2,2,6,6-tetramethyl-4-piperidinyl palmitate
  • 19615-3 N-P — 2,5-Furandione, polymer with ethenylbenzene, ester with α-alkyl-ω-hydroxypoly(oxy-1,2-alkanediyl), compd. with 2-(dialkylamino)alkanol
  • 19616-4 N — Isocyanic acid, polyalkylenepolyphenylene ester, polymer with alkanediol, 2-alkoxyethanol- and 1(or 2)-(2-methoxymethylethoxy)alkanol-blocked
• The Order takes effect on the day it was registered (see October 4, 2022).

Who's affected#

• Companies that manufactured or imported any of these specific substances in Canada.
• Chemical formulators, suppliers, or product makers that use these substances.
• Minister of the Environment and Minister of Health, who received the information used to add the substances.
• The wider public only indirectly — the change is mainly about how regulators track and assess chemicals.
• If it’s unclear whether a specific business or product is affected, those businesses should check the listed CAS numbers and chemical names against their inventories.

Why it matters#

• Being added to the Domestic Substances List means these chemicals are now officially recorded as “existing” in Canada.
• That listing reflects that someone reported manufacturing or importing these substances above the notification threshold under the New Substances rules.
• The listing itself does not impose new bans or limits, but it affects how regulators monitor, assess, and possibly manage these substances in the future.
• Businesses that use or handle these chemicals may want to confirm their records and watch for any follow-up assessments or communications from regulators.
