New Chemicals Added to Domestic Substances List

Summary#

This is Order 2021-87-12-01 Amending the Domestic Substances List: SOR/2021-263, a federal order that adds several chemicals to the Domestic Substances List under the Canadian Environmental Protection Act, 1999. It was registered on December 21, 2021 and published in the Canada Gazette on January 5, 2022.

What it does#

• Adds new entries to the Domestic Substances List inventory used by federal regulators.

• Part 1 — added these CAS-like identifiers:

  • 541-41-3
  • 29297-55-0
  • 381164-41-6
  • 1415043-98-9

• Part 3 — added these entries (identifier then name as listed):

  • 19532-0 — Formaldehyde, polymer with 2-phenoxyethanol and α-phenyl-ω-hydroxypoly(oxy-1,2-alkanediyl), dihydrogen phosphate 2-phenoxyalkyl hydrogen phosphate, metal salt
  • 19543-1 — 2,5-Furandione, polymer with alkenylbenzene, ester with α-butyl-ω-hydroxypoly[oxy(alkyl-1,2-ethanediyl)], 2-phenylalkyl imide, imide with polyethylene-polyalkylene glycol 2-aminoalkyl Me ether
  • 19544-2 — 2,5-Furandione, polymers with chlorinated polyalkylene, epichlorohydrin and 4,4′-(1-methylethylidene)bis[cyclohexanol], Bu esters
  • 19545-3 — 2-Alkenoic acid, polymer with alkenylbenzene and (1-alkylethenyl)benzene, compd. with 2-dialkylaminoethanol
  • 19546-4 — Poly(oxy-1,2-ethanediyl), α-hydro-ω-hydroxy-, polymer with 1,6-diisocyanatohexane and alcohols, ethoxylated
  • 19547-5 — Formic acid, compds. with bisphenol A-carbomonocyclicamine-epichlorohydrin polymer-hydrolyzed N‑1-(1,3-dimethylbutylidene)-N2-[2-[(1,3-dimethylbutylidene)amino]ethyl]-1,2-ethanediamine-2-(methylamino)ethanol reaction products
  • 19548-6 — Hexanedioic acid, polymer with 2,2-dimethylalkanediol, 1,6-hexanediol, 3-hydroxy-2-(hydroxymethyl)-2-methylpropanoic acid and 1,1′-methylenebis[4-isocyanatocyclohexane], compd. with 1-ethylpiperidine
  • 19549-7 — 2-Propenoic acid, 2-methyl-, alkyl ester, polymer with alkyl 2-propenoate, alkyl 2-propenoate, alkyl 2-propenoate and alkyl 2-methyl-2-propenoate
  • 19550-8 — (Poly(oxy-alkanediyl), α-(substituteddocosyl)-ω-[(substituteddocosyl)oxy]-)
  • 19551-9 — Alkenes, polymers with disubstituted heteromonocycle, substituted

• The order states that no additional conditions under the Act are in effect for these substances.

• The order comes into force on the day it was registered — December 21, 2021.

Who's affected#

• Companies that manufacture or import the added substances in Canada.
• Chemical suppliers and businesses that use these specific polymers or compounds in products.
• Regulators at federal departments who track and assess substances on the Domestic Substances List.
• The order itself notes that the substances were reported as manufactured or imported in Canada above thresholds set in the New Substances Notification Regulations (Chemicals and Polymers); if you are unsure whether a listed identifier matches something you make or sell, check product specifications or ask your supplier.

Why it matters#

• Being added to the Domestic Substances List is an official record that these chemicals have been reported in Canada at quantities above notification thresholds.
• That status affects what companies must tell regulators when they first bring a chemical into Canada and can change what follow-up reviews or oversight apply.
• For most people, this is an administrative update. For businesses in chemical production, import, or supply chains, it can change reporting duties and how regulators track the substances.
• The order does not itself announce new controls or bans for these substances; it simply adds them to the inventory.
