The Cosmetic Ingredient Hotlist is an administrative tool that Health Canada uses to communicate to manufacturers and others that certain substances, when present in a cosmetic, may violate the general prohibition found in section 16 of the Food and Drugs Act or in a provision of the Cosmetic Regulations. In doing so, it provides a mechanism for substances with known uses in cosmetics to be prohibited from meeting the definition of a cosmetic.

Health Canada has opened for comment a new proposal to update the Cosmetic Ingredient Hotlist. Included in the proposal are changes to existing entries as well as the addition of new substances to be restricted and/or prohibited.

Ingredients and changes to the Hotlist include:

  • Removing Dihydrocoumarin (CAS 119-84-6) from the prohibited substance list and adding restrictions to allow up to a maximum of 0.035% in a leave-on product and up to 3.5% in a rinse-off product
  • Revising entries for Disulfiram, Thiuram, Thiuram disulfides, and Thiuram monosulfides to combine under a single entry for Thiurams (CAS 97-77-8; 137-26-8) with a maximum use of 14% in latex products
  • Revising the entry for products containing Eucalyptus oil (CAS 8000-48-4) by adding the warning: “This product contains eucalyptus oil which is poisonous.", "Keep out of reach of children", and "If swallowed, call a Poison Control Center or doctor immediately.”
  • Revising the restriction on Sodium bromate (CAS 7789-38-0) to a prohibition for all Bromates
  • Revising the entry for Thioglycolic acid (CAS 68-11-1) and its salts as follows:
Ingredient CAS Restriction
Conditions of Use by product type Maximum Concentration Permitted Warnings and Cautionary Statements (to the effect of)
Thioglycolic acid and its salts 68-11-1 a) Eyelash curling products a) 11% with a pH of 7 to 9.5 a) "For professional use only.", "Avoid direct skin contact, wear suitable gloves.", "Avoid contact with eyes and, in the event of contact with eyes, rinse immediately with plenty of water and seek medical attention."
b) Hair dyes, waving or straightening products b) 8% with a pH of 7 to 9.5 b) "Avoid direct skin contact, wear suitable gloves.", "Not for use in the area of the eye."
c) Hair dyes, waving and straightening products for professional use c) 11% with a pH of 7 to 9.5 c) "For professional use only.", "Avoid direct skin contact, wear suitable gloves.", "Not for use in the area of the eye."
d) Depilatory products d) 5% with a pH of 7 to 12.7 d) "Avoid contact with eyes and, in the event of contact with eyes, rinse immediately with plenty of water and seek medical attention."

Other minor changes including new synonyms and CAS number changes have also been made. Despite the notification, Health Canada points out parties should abide by the general prohibition that the sale of cosmetics should cease as soon as it is known to cause injury. Health Canada proposes Hotlist updates on an as needed basis and it was last updated in September 2018.

Next step:

Health Canada invites stakeholders to submit comments on the proposed updates by no later than July 1, 2019.
