Cosmetic Ingredient Hotlist and Proposed Updates

 In Cosmetics


What is the Canadian Cosmetic Ingredient Hotlist?

The Cosmetic Ingredient Hotlist is a tool that Health Canada uses to inform companies and consumers in Canada of the prohibitions and restrictions that exist for some substances. It is an important component of Canada’s cosmetic regulations. Careful inspection of the Hotlist is important as those present may impact a products compliance with the Food and Drugs Act or the Cosmetics Regulations. The Hotlist is also a useful tool in distinguishing between cosmetic products and registered product, such a Drug or Natural Health Product. Dell Tech’s team provides professional, confidential consulting services to assist companies with Canada’s cosmetic regulations. Our services include product classification, formula assessment against the cosmetic ingredient hotlist, label development and submission of a Cosmetic Notification Form.

Background on These Updates

Occasionally Health Canada will put forward proposed updates or additions to the Hotlist. Examples of changes include new restricted ingredients or a new maximum concentration allowance. This is typically done when new scientific data on a substance becomes available. This information can be sourced through a science based document like a peer-reviewed journal and can come from national and international experts.  Recently, Health Canada issued a proposal for new changes. Please see the below lists of changes that are proposed:

  2. Thioglycolic acid esters (CAS #’s 30618-84-9, 25103-09-7): This substance is being considered due to its high risk of skin sensitization.

Revisions to Existing Entries:

  1. p-Cresol and mixtures thereof (CAS #’s 106-44-5, 1319-77-3): Suggestion to differentiate between different cresols in the Hotlist. See also proposed entries for m-Cresol and o-Cresol.
  2. Secondary alkyl- and alkanolamines and their salts (CAS #’s 111-42-2, 110-97-4, 69331-39-1, 61693-41-2, 58855-63-3, 124-20-9, 334-50-9, 108-18-9): Proposed addition of Secondary alkyl- and alkanolamines and their salts to existing Dialkanolamines, secondary

Proposed Changes to the Restricted List:


  1. Benzophenone (CAS # 119-61-9): Information from the Chemicals Management Plan assessment describes this substance as potentially causing adverse maternal effects. The proposed restriction is a maximum of 3%.
  2. p-Chloro-m-cresol or Chlorocresol (CAS # 59-50-7): Information from the Chemicals Management Plan assessment describes this substance as restricted due to its effect on adrenal organs. Proposal to restrict use to 0.1% in cosmetics that are not used near mucosal membranes.
  3. Retinal (CAS # 116-31-4): Proposed to be added to restricted list die to potential skin irritation and its therapeutic properties.
