Should Two Industrial Lubricant Chemicals Be Restricted in Consumer Spray Products?

Official title: Publication of summary of the assessment of two substances — 1-decene, dimer, hydrogenated (hydrogenated didecene), CAS RN 68649-11-6, and 1-decene, tetramer, mixed with 1-decene trimer, hydrogenated (HTTD), CAS RN 68649-12-7 — specified on the Domestic Substances List and of Ministerial Statements (section 77 of the Canadian Environmental Protection Act, 1999)

Open Regulations & Permits Environment & Climate Health & Safety
The government found that two chemicals used in lubricant and cleaner sprays—hydrogenated didecene and HTTD—are toxic under environmental law. They're proposing to restrict these substances in consumer spray products like lubricants and preservatives. You have 60 days to comment on how they plan to regulate these chemicals.

Why This Matters

Use spray lubricants around the house? These chemicals are in products you might have in your garage or workshop. The government says they're toxic and wants to limit what manufacturers can put in consumer sprays. If you work with these products regularly, this could change what's on store shelves.

What Could Change

These two chemicals would be added to the toxic substances list under environmental law. New regulations would restrict their use in cleaner, lubricant, and preservative spray products sold to consumers. Manufacturers may need to reformulate products or face restrictions on what they can sell.

Key Issues

  • Should hydrogenated didecene and HTTD be added to the toxic substances list?
  • How should these chemicals be restricted in consumer spray products?

How to Participate

  1. Review the risk management approach document on the Chemical substances website to understand the proposed restrictions.
  2. Submit written comments to the Minister of the Environment within 60 days of publication (by January 21, 2026).
