New substances added to Domestic Substances List

Summary#

This is Order 2022-87-11-01 Amending the Domestic Substances List (SOR/2022-269) made under the Canadian Environmental Protection Act, 1999. It adds several chemical substances (listed by CAS number and names) to the Domestic Substances List. The order was registered and came into force on December 13, 2022; it was signed by Steven Guilbeault, Minister of the Environment.

What it does#

• Adds two entries to Part 1 of the Domestic Substances List:
  • 67757-47-5 N
  • 1138156-39-4 N-P
• Adds several entries to Part 3 of the Domestic Substances List (each shown with its CAS-like number and the chemical/polymer name given in the order):
  • 19627-5 — Paraffin waxes and hydrocarbon waxes, derivatized, polymers with acrylic acid, 2-ethylhexyl acrylate, fumaric acid, polyethylene glycol ether with bisphenol A (2:1), polypropylene glycol ether with bisphenol A (2:1), styrene, terephthalic acid and trimellitic anhydride, tert‑Bu peroxide‑initiated
  • 19628-6 — Phosphorous acid, triphenyl ester, polymer with carbomonocycledimethanol and α‑hydro‑ω‑hydroxypoly[oxy(methyl‑1,2‑ethanediyl)], alkyl esters
  • 19629-7 — 1,3‑Benzenedicarboxylic acid, polymer with hexanedioic acid, polyalkylalkanediol, 1,2‑propanediol and 1,6‑hexanediol
  • 19630-8 — 1,3‑Benzenedicarboxylic acid, polymer with alkanedioic acid, 2,2‑dimethyl‑1,3‑propanediol and 1,2‑ethanediol
  • 19631-9 — 2‑Propenoic acid, 2‑alkyl‑, 2‑alkylalkyl ester, polymer with 2‑propenoic acid, ammonium salt, peroxydisulfuric acid ([(HO)S(O)2]2O2) diammonium salt‑initiated
  • 19632-0 — 2‑Propenoic acid, alkyl‑, alkylalkyl ester, polymer with 2‑propenoic acid, sodium salt, peroxydisulfuric acid ([(HO)S(O)2]2O2) diammonium salt‑initiated
  • 19633-1 — 1,4‑Benzenedicarboxylic acid, polymer with 2,2‑dimethyl‑1,3‑propanediol, hexanedioic acid and 1,2‑propanediol, dihydrogen 2‑substituted‑1,2,3‑propanetricarboxylate
  • 19634-2 — 1,3‑Benzenedicarboxylic acid, polymer with 1,4‑benzenedicarboxylic acid, butanedioic acid, (2E)‑2‑butenedioic acid, 1,3‑dihydro‑1,3‑dioxo‑5‑isobenzofurancarboxylic acid, dihydro‑3‑(tetrapropenyl)‑2,5‑furandione, alkanedioic acid, α,α’‑[(1‑methylethylidene)di‑4,1‑phenylene]bis[ω‑hydroxypoly(oxy‑1,2‑ethanediyl)] and α,α’‑[(1‑methylethylidene)di‑4,1‑phenylene]bis[ω‑hydroxypoly[oxy(methyl‑1,2‑ethanediyl)]], benzoate octadecanoate

Who's affected#

• Companies that manufacture, import, supply or use the listed substances in Canada.
• Chemical distributors and product formulators who handle the specific polymers or ingredients named above.
• Government regulators tracking which chemicals are on the national list.
• The order text does not say which consumer products or industries use these exact substances, so it may not be obvious to the general public whether everyday products they buy are affected.

Why it matters#

• Being added to the Domestic Substances List is an official, administrative change that records these substances in Canada’s inventory of tracked chemicals.
• For businesses, the change can affect regulatory reporting and how the federal government monitors and assesses chemicals.
• For the public, this update is part of how Canada keeps an official record of substances that are present or used in the country; it helps regulators decide what further information or action, if any, is needed.
