• Adds the following substances (CAS number plus chemical name) to Part 3 in numerical order:
  • 19704-2 — 2‑Oxepanone, polymer with polyhydroheteromonocycle-substituted, ester with alkyl hydroxypoly(oxy-1,2-alkanediyl), phosphate
  • 19720-8 — 2‑Propenoic acid, 2‑methyl-, polymer with alkyl 2‑propenoate, 1,1′-(1,6-hexanediyl) di-2-propenoate, 2-hydroxyethyl 2-methyl-2-propenoate, 2-hydroxyethyl 2-propenoate and methyl 2-methyl-2-propenoate
  • 19722-0 — Glycols, α,ω-, C2-6, polymers with adipic acid, 1,10-decanediol, 1,12-dodecanediol, fumaric acid, 1,9-nonanediol, sebacic acid and succinic acid, alkyl esters, stearates
  • 19723-1 — Fatty acids, C18-unsatd., dimers, polymers with adipic acid dihydrazide, glycidyl neodecanoate, α-hydro-ω-hydroxypoly(oxy-1,4-butanediyl), 3-hydroxy-2-(hydroxymethyl)-2-methylpropanoic acid, 5-isocyanato-1-(isocyanatomethyl)-1,3,3-trimethylcyclohexane, oxoalkanoic acid, polypropylene glycol and trimethylolpropane, compds. with triethylamine
  • 19726-4 — 2‑Propenoic acid, 2‑methyl-, 1,1′-(1,2-ethanediyl) ester, polymer with butyl 2‑propenoate, α-[[[[5-[[(2-carboxy-3-hydroxy-2-methylpropoxy)carbonyl]amino]-1,3,3-trimethylcyclohexyl]methyl]amino]carbonyl]-ω-[[[[[1,3,3-trimethyl-5-[[[2-[(2-methyl-1-oxo-2-propen-1-yl)oxy]ethoxy]carbonyl]amino]cyclohexyl]methyl]amino]carbonyl]oxy]poly(oxyalkanediyl) compd. with 2-(dimethylamino)ethanol and 1,2-propanediol mono(2-methyl-2-propenoate)
  • 19727-5 — 2‑Propenoic acid, alkyl-, polymers with alkyl acrylate and polyethylene glycol methacrylate branched alkyl ether
• The Order states it comes into force on the day it is registered (registration date: July 24, 2024).

Who's affected#

• Companies that make, import, sell, or use the listed chemicals or products that contain them.
• Chemical suppliers, formulators, and downstream industrial users who track regulatory lists.
• Environmental and public health groups that follow changes to the Domestic Substances List.
• The notice does not describe specific businesses or sectors by name, so it is unclear beyond those general groups which industries will be most impacted.

Why it matters#

• The Domestic Substances List is Canada’s official inventory of chemicals that are or have been in Canadian commerce. How a substance is listed can influence whether and how federal authorities review or regulate it.
• Businesses that handle the listed substances should check the change to see if it affects reporting, compliance, or risk-assessment requirements.
• For the public, the update shows ongoing federal tracking and administrative changes to the chemicals that may be present in products, manufacturing, or the environment.
