Should Two Flame Retardant Chemicals Be Regulated?

Official title: Publication of supplemental material after draft screening assessment of the Flame Retardants Group, including phosphoric acid, triphenyl ester (triphenyl phosphate; TPHP), CAS RN 115-86-6, and ethanol, 2-butoxy-, phosphate (3:1) [tris(2-butoxethyl) phosphate; TBOEP], CAS RN 78-51-3, specified on the Domestic Substances List (section 77 of the Canadian Environmental Protection Act, 1999)

Open Regulations & Permits Environment & Climate Health & Safety
The government is reconsidering whether two flame retardant chemicals—TPHP and TBOEP—pose risks to health or the environment. New information has emerged since the original 2021 assessment. TPHP was already flagged as potentially toxic, but now TBOEP may also meet the criteria for regulation.

Why This Matters

Flame retardants are in furniture, electronics, and building materials throughout your home. If these chemicals are found to be toxic, manufacturers may need to reformulate products. That could mean safer household items—or higher prices as companies adjust.

What Could Change

TBOEP may now be added to Canada's toxic substances list alongside TPHP. This would trigger mandatory risk management measures. Manufacturers using these chemicals could face new restrictions or reporting requirements.

Key Issues

  • Does new evidence show TBOEP is toxic when the 2021 assessment said it wasn't?
  • What risk management measures should apply to TPHP and TBOEP?

How to Participate

  1. Review the additional risk characterization document and the risk management scope to understand the proposed changes.
  2. Submit comments to substances@ec.gc.ca by the deadline.
