August 2022 Changes to the Cosmetic Ingredient Hotlist

Items Added

Ethylhexyl Ethylhexanoate

This ingredient was added to the list of restricted substances due to health concerns, as assessed by the Government of Canada's Chemicals Management Plan (CMP) under the Canadian Environmental Protection Act, 1999 (CEPA 1999).

Azelaic acid and its salts

These ingredients were added to the list of restricted substances due to known therapeutic properties and risk of skin irritation at concentrations above the maximum permitted concentration of 14%.

Items Amended

Retinoic acid and its salts

This entry was amended to add salts for clarity. Salts are expected to convert to retinoic acid when mixed in solution. Retinoic acid has known therapeutic action at low concentration, with marketed prescription drugs for topical use containing retinoic acid at a concentration as low as 0.01% listed in Health Canada’s Drug Product Database.

Eucalyptus oil

The entry was amended to better mitigate the risk of unintentional ingestion, particularly in pediatric populations, by introducing cautionary label statements for certain products with concentrations greater than 0.022%.

Peroxide and peroxide-generating compounds

The entry was amended to clarify that for oral cosmetics containing more than 3% hydrogen peroxide (or equivalent) hydrogen peroxide concentrations in saliva will continue to be requested but, concentrations within the soft tissue of the oral cavity will not be routinely requested. Furthermore, the statement allowing evidence that may include analog studies from recognized sources or independent clinical research was removed.

p-Hydroxyanisole

The entry was amended to expand the permitted nail product categories to include products for consumer use, and increase the maximum concentration permitted for these products.

December 2019 Changes to the Cosmetic Ingredient Hotlist

Items Amended

Dihydrocoumarin

This entry was amended from a prohibition to a restriction. The ingredient is naturally occurring in some plant derivatives at low levels. A review of the available scientific data indicated that the ingredient may cause sensitization at higher concentrations but can be used at low levels without significant risk.

Disulfiram, Thiuram, Thiuram disulfides, and Thiuram monosulfides

These entries were amended to combine the substances under a single entry for Thiurams. The revised entry also encompasses thiuram tetrasulfides which were not previously captured under the Hotlist entries. These substances were all identified to pose similar skin sensitization risks. The combined Hotlist entry was also revised from a prohibition to a restriction because a review of the available scientific data indicated that the ingredients may cause skin sensitization under certain usage conditions but can be used in latex theatrical makeup without significant risk.

Sodium bromate

This entry was amended from a restriction to a prohibition. Sodium bromate is toxicologically equivalent to potassium bromate, which has been prohibited since March 2011 due to its carcinogenic potential, as assessed by the Government of Canada's Chemicals Management Plan (CMP) under the Canadian Environmental Protection Act, 1999 (CEPA, 1999). The two entries were combined into one entry for Bromates.

Thioglycolic acid and its salts

This entry was amended to include new conditions regarding hair dye products and products for use in the area of the eye due to changes in ingredient usage. 

September 2018 Changes to the Cosmetic Ingredient Hotlist

Items Added

Cannabis, as defined in subsection 2(1) of the Cannabis Act (see the Cannabis Exemption (Food and Drugs Act) Regulations for details)

This entry was added to the list of prohibited substances as result of the coming into force of the Cannabis Act. Previously, cannabis was subject to the Controlled Drugs and Substances Act, and these ingredients were prohibited under the Narcotics, natural and synthetic entry. Products containing these ingredients are exempted from the application of the Food and Drugs Act as a result of the Cannabis Exemption (Food and Drugs Act) Regulations.

Items Amended

Cannabis sativa seed oil and Hydrolyzed Hemp seed protein

These entries were combined into a single, broadened entry to better reflect the requirements of the Industrial Hemp Regulations: Cannabis spp. (hemp) derivatives that are exempt from the Cannabis Act under the Industrial Hemp Regulations.

June 2018 Changes to the Cosmetic Ingredient Hotlist

Items Amended

Methylisothiazolinone (MI)

This entry was amended in order to add a new condition for MI, as a prohibited substance in leave-on cosmetic products and reduce the maximum allowed concentration in rinse-off products to 0.0015% due to the risk of sensitization. If a mixture of Methylisothiazolinone and Methylchloroisothiazolinone (MI/MCI) is used in the same product as Methylisothiazolinone alone (MI), the total concentration of MCI/MI and MI, combined, cannot exceed 0.0015%.

Methylisothiazolinone / Methylchloroisothiazolinone (MI/MCI), in combination

This entry was amended to clarify that if the mixture of Methylisothiazolinone and Methylchloroisothiazolinone (MI/MCI) is used in the same product as Methylisothiazolinone alone (MI), the total concentration of MCI/MI and MI, combined, cannot exceed 0.0015%.

Oleandrin

This entry was removed. The substance is now captured by a new, expanded entry for Nerium oleander, its extracts and glycosides. All parts of the Nerium oleander plant, including the sap, are toxic.

Chloramine T

This entry was amended to add related compounds for clarity. The additional compounds are expected to convert to Chloramine T when mixed in solution. Exposure to Chloramine T can result in skin and respiratory sensitization.

Items Added

Pigment Red 4

This ingredient was added to the list of restricted substances with a maximum concentration of 3% permitted. Action was taken due to potential health concerns, as assessed by the Government of Canada's Chemicals Management Plan (CMP) under the Canadian Environmental Protection Act, 1999 (CEPA 1999).

December 2015 Changes to the Cosmetic Ingredient Hotlist

Format Changes:

The table format has been further improved by removing repeated text and adding an extra column in the restricted table in order to highlight the maximum concentration permitted and entries have been reworded in order to ensure consistency and clarity.

Items Amended:

• Methylisothiazolinone / Methylchloroisothiazolinone (MI/MCI), in combination. This entry was amended in order to add a new condition for MI/MCI when used in combination, as a prohibited substance in leave-on cosmetic products. The preservative can still be used in rinse-off products, to a maximum concentration of 0.0015% or 15 ppm.
• Cyanoacrylate-based adhesives. This entry was amended in order to reflect the policy change in requirements for cyanoacrylate-based eyelash adhesives. Notifiers of cyanoacrylate-based adhesives for the application of false eyelashes will no longer be required to submit descriptions of their training methods and training materials to Health Canada upon notification. However, these materials should be kept on hand.
• Peroxide and peroxide-generating compounds. In order to better reflect current use patterns for tooth whitening products, this entry was amended by updating the cautionary statements.
• p-Phenylenediamine and its salts. This entry was amended in two ways:
  1. Addition of a maximum concentration limit of 3% after dilution with an oxidizer, and
  2. Addition of p-Phenylenediamine salts to the list of synonyms and related compounds.

Items Added:

• Prostaglandins, their salts, derivatives and analogs. Prostaglandins and their analogs were added as prohibited ingredients in cosmetic products due to their presence on the Prescription Drug List and their sole therapeutic functions.
