Health Canada's 2026 Cosmetic Ingredient Hotlist Changes: What Formulators Must Do Before the Amendments Land

Health Canada has moved to tighten the Cosmetic Ingredient Hotlist, the list that decides which ingredients can and cannot go into a cosmetic sold in Canada. Between 19 November 2025 and 17 February 2026 the department ran a public consultation on new prohibited and restricted entries. That comment window has now closed, which means the proposals are moving toward a final, published Hotlist. For any brand that formulates or imports cosmetics, that is the moment to act, because a Hotlist change can turn a compliant product into a non-compliant one without a single change to your formula.

This guide explains what the Hotlist is, exactly what Health Canada proposed, why a closed consultation still matters, and the concrete steps formulators, importers and their quality teams should take now. It is written for cosmetics and personal care companies selling into Canada, including those that also serve the European Union and United States markets.

Executive summary

The Cosmetic Ingredient Hotlist is Health Canada's administrative list of substances that are prohibited or restricted in cosmetics. In its 2025 to 2026 consultation, Health Canada proposed adding restrictions on Basic Violet 4, Basic Blue 7 and polyaminopropyl biguanide (PHMB), expanding the prohibition on comfrey (Symphytum) species, moving brucine from restricted to fully prohibited, and tightening controls on furocoumarins. The consultation closed on 17 February 2026, so companies should treat the proposals as the likely shape of the final Hotlist and begin reviewing formulas, certificates and Cosmetic Notification Forms now, rather than waiting for the updated list to be published.

What is the Cosmetic Ingredient Hotlist?

In short: the Cosmetic Ingredient Hotlist is the tool Health Canada uses to communicate which substances are prohibited or restricted in cosmetics sold in Canada. It is not a regulation on its own. Instead, it identifies ingredients that, if present, may cause a cosmetic to contravene the Food and Drugs Act or the Cosmetic Regulations. Health Canada's Consumer and Hazardous Products Safety Directorate maintains it and updates it as new safety science emerges.

Entries fall into two groups. A prohibited substance must not be present in a cosmetic at all. A restricted substance is allowed only under stated conditions, such as a maximum concentration, a limit to certain product types, or a required warning or instruction. Because the Hotlist is administrative, Health Canada can revise it without going through the full regulatory amendment process in the Canada Gazette. That is convenient for regulators and risky for companies, because the practical effect of a new entry can be immediate.

The Hotlist sits alongside the mandatory notification requirement in the Cosmetic Regulations. Selling a cosmetic in Canada is not a licensing process like a drug or a natural health product. It is a notification process, backed by the expectation that every ingredient is safe and compliant. The Hotlist is where Health Canada draws many of those safety lines. For a broader view of how quality systems support cosmetic compliance, see our guide to cosmetics GMP and ISO 22716.

What Health Canada proposed in 2025 to 2026

In short: Health Canada proposed three new restricted entries (Basic Violet 4, Basic Blue 7 and PHMB) and revisions to three existing areas (Symphytum species, brucine and furocoumarins). The changes touch hair dyes, rinse-off and leave-on products, nail and bath products, and botanically derived ingredients. The table below summarizes each proposal and Health Canada's stated rationale.

New restricted entries

The two hair dye colourants, Basic Violet 4 and Basic Blue 7, would be prohibited in leave-on hair products and capped in the products where they remain allowed. If your portfolio includes semi-permanent colours, tinting conditioners or leave-in colour-refreshing products, these entries deserve immediate attention. PHMB, a widely used preservative and antimicrobial, would be prohibited in sprays and aerosols and limited to 0.2 percent elsewhere. Any pump mist, setting spray or aerosol that relies on PHMB would need reformulation.

Revised and expanded entries

The comfrey (Symphytum) change closes a previously allowed exception for Symphytum officinale, so botanical and natural-positioned skincare lines that use comfrey extracts should reassess. Brucine would move from a restricted substance to a fully prohibited one, and the prohibition would expressly capture its salts. Furocoumarins, found naturally in citrus and certain botanical oils, would be prohibited as intentionally added ingredients, with a very low ceiling of 1 part per million for naturally occurring amounts in leave-on products. Citrus-forward facial oils and bergamot-containing formulations are the obvious risk points here.

Why a closed consultation still matters

In short: the comment period closed on 17 February 2026, but that does not make the proposals irrelevant. It means Health Canada is now reviewing the feedback it received and preparing the final Hotlist. Once the updated list is published, the new prohibitions and limits apply, and products that do not meet them may be treated as non-compliant.

Unlike a regulation published in the Canada Gazette, a Hotlist update does not usually come with a long, formal transition period. In practice, the revised list tends to take effect on publication. That means the lead time you have to reformulate, source alternatives, generate stability data and change labels is lead time you create for yourself by acting before publication, not after. Companies that wait for the final Hotlist to appear will be reacting under time pressure, often with SKUs already on shelves.

It is worth separating this consultation from another 2026 cosmetics change that brands sometimes confuse it with. The prohibited and restricted ingredient proposals covered here are distinct from the new fragrance allergen disclosure requirements, which concern labelling rather than banned ingredients. We cover those separately in our fragrance allergen disclosure and reformulation roadmap. A well-run cosmetics compliance programme needs to track both.

How the Hotlist connects to notification and your quality system

In short: a Hotlist change ripples into your Cosmetic Notification Form, your ingredient specifications and your supplier documentation. Under the Cosmetic Regulations, any company that manufactures or imports a cosmetic for sale in Canada must notify Health Canada using a Cosmetic Notification Form (CNF) within 10 days of first sale. If a reformulation changes your ingredient list or concentrations, the notification must reflect the current formula.

For importers, the exposure is often greater than expected. When you import a finished cosmetic, you inherit responsibility for whether that product meets Canadian requirements, including the Hotlist. A colourant or preservative that is acceptable in the country of manufacture may sit above a Canadian limit or fall inside a new prohibition. Your incoming quality checks, supplier agreements and specification sheets are the controls that catch this before the product reaches a Canadian consumer.

The disciplined way to manage a Hotlist change is to treat it as a controlled change inside your quality system. Identify every affected stock keeping unit, assess the reformulation options, document the decision and its safety rationale, update internal specifications, refresh supplier certificates, and update the CNF. That is the same change-control logic MFLRC helps clients build through quality assurance and documentation services.

What formulators and importers should do now

In short: review your portfolio against the proposed entries, confirm concentrations, identify substitutes for at-risk ingredients, gather updated supplier documentation, and plan the Cosmetic Notification Form updates that any reformulation will require. The checklist below turns that into concrete steps.

Compliance checklist

• Inventory affected products. List every SKU that contains Basic Violet 4, Basic Blue 7, PHMB, comfrey (Symphytum) extracts, brucine or furocoumarin-bearing botanicals such as citrus and bergamot oils.
• Check concentrations and product type. Compare each formula against the proposed limits, paying attention to leave-on versus rinse-off, sprays and aerosols, and nail and bath products.
• Flag the leave-on and aerosol risks first. Leave-on hair products, setting sprays and aerosols face outright prohibitions for several of these ingredients, so they carry the highest urgency.
• Identify substitutes. Work with your formulators and suppliers to select compliant alternatives, and plan the stability and compatibility testing each substitution needs.
• Request updated supplier documentation. Obtain current certificates of analysis, specifications and safety information for reformulated inputs, especially for imported finished goods.
• Plan Cosmetic Notification Form updates. Map which CNFs will need to be amended once formulas change, and prepare the submissions so they are ready when the reformulation is complete.
• Review claims and marketing. Confirm that any ingredient-based marketing claims remain accurate after reformulation, so your labels and website do not reference removed ingredients.
• Document the safety rationale. Keep the reasoning and supporting information for each reformulation on file, in case Health Canada asks.
• Watch for the final Hotlist. Assign someone to monitor Health Canada's Cosmetic Ingredient Hotlist page so you know the moment the updated list is published.

Common mistakes to avoid

• Assuming a closed consultation means nothing will change. The opposite is true. A closed comment period means the department is finalizing, not abandoning, the proposals.
• Waiting for a transition period that may not come. Hotlist updates typically apply on publication, without the multi-year runway of a Gazetted regulation.
• Treating imported finished goods as someone else's problem. The Canadian importer is responsible for Hotlist compliance, even when the product was formulated abroad.
• Forgetting the notification update. Reformulating without updating the Cosmetic Notification Form leaves your official record out of step with the product you actually sell.
• Overlooking naturally occurring substances. Furocoumarins in citrus oils and pyrrolizidine alkaloids in comfrey are not always listed as intentional ingredients, yet they are exactly what the proposals target.
• Confusing the ingredient Hotlist with fragrance allergen disclosure. They are separate 2026 workstreams with different obligations, and both need to be tracked.

Frequently asked questions

What is the Cosmetic Ingredient Hotlist?

It is Health Canada's administrative list of substances that are prohibited or restricted in cosmetics sold in Canada. It is not a standalone regulation, but a product containing a Hotlist substance in breach of the stated conditions may be considered to contravene the Food and Drugs Act or the Cosmetic Regulations.

Is the 2026 Hotlist consultation still open?

No. The consultation on proposed updates to the prohibited and restricted ingredients opened on 19 November 2025 and closed on 17 February 2026. Health Canada is now reviewing feedback and preparing the final Hotlist, so the window to submit comments has passed but the window to prepare has not.

Which ingredients did Health Canada propose to restrict or prohibit?

The proposals add restrictions on Basic Violet 4, Basic Blue 7 and polyaminopropyl biguanide (PHMB), expand the prohibition on Symphytum species by removing the comfrey exception, move brucine and its salts from restricted to prohibited, and tighten furocoumarin controls, including a 1 part per million ceiling for naturally occurring amounts in leave-on products.

Do Hotlist changes come with a transition period?

Usually not in the way a Gazetted regulation does. A Hotlist update generally applies when the revised list is published. That is why preparing before publication, rather than after, is the single most valuable thing a brand can do.

Does a reformulation mean I have to update my Cosmetic Notification Form?

Yes. If the ingredient list or concentrations of a notified cosmetic change, the Cosmetic Notification Form should reflect the current formula. Reformulating quietly and leaving the notification unchanged creates a mismatch that can surface during a Health Canada review or a complaint investigation.

How is this different from the 2026 fragrance allergen disclosure change?

The ingredient Hotlist governs whether a substance can be used at all, and under what conditions. The fragrance allergen disclosure requirement governs how certain allergenic fragrance components must be declared on the label. Both are 2026 cosmetics compliance issues in Canada, but they are separate obligations, and a strong programme manages both.

How MFLRC can help

MF License and Regulatory Consultants works with cosmetics and personal care companies across Canada, the United States and the European Union. For the Hotlist changes specifically, we can review your full ingredient list against the proposed prohibitions and limits, prioritize the leave-on and aerosol products that carry the most risk, help you and your formulators select compliant substitutes, and prepare the regulatory affairs, licensing and notification support that a reformulation requires, including Cosmetic Notification Form updates.

We also help brands build the change-control and documentation discipline that turns a regulatory surprise into a routine, well-managed update, so the next Hotlist revision is something your quality system absorbs rather than scrambles to catch.

Conclusion

Health Canada's proposed Cosmetic Ingredient Hotlist changes are a reminder that cosmetic compliance in Canada is not a one-time notification, but an ongoing responsibility. The consultation has closed, the proposals are being finalized, and the practical effect can arrive quickly once the updated list is published. Brands that inventory their formulas now, plan substitutions, and line up their Cosmetic Notification Form updates will move through the change calmly. Those that wait will be reformulating against a live compliance gap. The better path is clear, and there is still time to take it.
