Health Canada has launched a consultation on proposed updates to the Cosmetic Ingredient Hotlist. These changes are intended to enhance consumer safety by restricting or prohibiting certain ingredients based on new safety data.

Proposed Additions (New Restrictions):

The following ingredients are being added to the Hotlist with specific usage limits:

-Basic Violet 4 (CI 42600, CAS 2390-59-2)

  • Prohibited in leave-on hair products
  • Restricted to a maximum of 0.4% in hair dyes and 0.2% in rinse-off hair care products

-Basic Blue 7 (CI 42595, CAS 2390-60-5)

  • Prohibited in leave-on hair products
  • Restricted to maximum concentrations in hair dyes (0.4%), rinse-off hair care (0.2%), nail products (0.8%), and bath products (2%).

-Polyaminopropyl Biguanide (PHMB) (CAS CAS 32289-58-0; 27083-27-8; 28757-47-3)

  • Prohibited in spray or aerosol formulations due to lung risks from inhalation
  • Restricted to a maximum of 0.2% in all other cosmetics

Proposed Revisions to Existing Entries:

Health Canada is proposing revisions for the following listed ingredients:

-Symphytum spp. (Comfrey)

  • Prohibited: The current exception for Symphytum officinale is being removed, banning the use of this ingredient due to concerns over toxic alkaloids.

-Brucine and its salts (CAS 357-57-3; 4845-99-2)

  • Prohibited: Previously restricted, this ingredient is now proposed for a total ban due to high toxicity and neurotoxic risks.

-Furocoumarins (CAS 66-97-7; 482-44-0; 642-05-7; 484-20-8; 298-81-7)

  • Restricted: Intentionally adding these is not permitted.
  • New Limits: Permitted only as trace contaminants in naturally occurring plant extracts, with a limit of 1 ppm (0.0001%) in all leave-on products (expanding the rule beyond just sun-tanning products).

-Imperatorin

  • Removed: The specific entry for this ingredient will be removed as it will now be regulated under the broader ‘Furocoumarins’ entry.

Stakeholders are encouraged to submit comments on the changes Health Canada is proposing. The comments can be emailed or sent in writing to the Hotlist Coordinator no later than February 17, 2026. At this time, you should be evaluating your market strategy should you have products impacted by these potential updates to the Hotlist, as you will be required to comply once updates to the Hotlist are published.
