Canada Fragrance Allergens in Cosmetics: New Rules for 2026

6/4/2026

Last updated: April 2, 2026 (CNF update confirmed)

Health Canada has introduced new requirements regarding the disclosure of fragrance allergens in cosmetic products sold in Canada.

These changes aim to improve transparency for consumers who may be sensitive to certain fragrance ingredients, while also introducing more flexibility for companies in how information is reported.

This article explains:

  • the new labeling requirements
  • the updated reporting expectations
  • the full compliance timeline through 2028

New fragrance allergen labeling requirements

Under the amended Cosmetic Regulations, fragrance allergens must be listed on cosmetic product labels when present above the following thresholds:

  • 0.01% in rinse-off products
  • 0.001% in leave-on products

These thresholds are aligned with international practices aimed at helping consumers identify substances that may trigger allergic reactions.

Compliance timeline for fragrance allergen labeling

Health Canada has introduced a phased implementation timeline:

  • As of April 12, 2026
    All new and existing cosmetic products must disclose 24 fragrance allergens within the ingredient list
  • As of August 1, 2026
    All new cosmetic products must disclose the expanded list of over 80 fragrance allergens
  • As of August 1, 2028
    All existing cosmetic products must comply with the expanded list of over 80 fragrance allergens

* When present at concentrations greater than 0.01% in rinse-off products and 0.001% in leave-on products

Changes to CNF reporting expectations

Following its March 2026 communication, Health Canada has now officially updated the Cosmetic Notification Form (CNF) and its guidance.

In most cases:

  • the concentration of certain fragrance allergens is no longer required
  • fragrance allergens must still be declared as individual ingredients

A new declaration logic has also been introduced:

  • one allergen per ingredient entry
  • a dedicated checkbox: “fragrance allergen present above disclosure threshold”

This confirms a clear regulatory shift:
more flexibility in reporting, but stricter expectations in compliance.

Important exception: restricted ingredients

An important exception applies when a fragrance allergen is also subject to restrictions under the Cosmetic Ingredient Hotlist.

In these cases, the concentration or concentration range remains mandatory.

Examples include:

  • eucalyptus
  • camphor
  • methyl salicylate

Companies should therefore verify whether fragrance allergens in their formulations are also listed as restricted ingredients.

Increased compliance expectations

Health Canada has also clarified enforcement expectations.

A cosmetic product may not be allowed for sale if:

  • the CNF is incomplete or outdated
  • required updates are not submitted
  • requested information is not provided

These clarifications reflect a broader strengthening of compliance expectations.

What this means in practice

These updates highlight an important distinction: labeling requirements remain strict and reporting obligations are becoming more flexible

For companies, preparation should focus on:

  • reviewing fragrance compositions
  • identifying allergens subject to disclosure
  • updating labeling strategies
  • anticipating CNF updates
  • structuring regulatory data

Where to find the full list of fragrance allergens

To support companies in identifying regulated fragrance allergens, a structured list is available covering currently regulated substances and upcoming requirements.

Conclusion

The new fragrance allergen requirements represent a significant regulatory shift in Canada.

While labeling obligations are becoming more detailed, Health Canada has introduced flexibility in reporting to support industry implementation.

With multiple deadlines between 2026 and 2028, early preparation is essential to ensure compliance and avoid disruptions.
