A timed bomb can sit inside a formulation that passed review six months ago. Health Canada's Cosmetic Ingredient Hotlist does not hold still, and its current round of proposals moves several plant-derived actives toward outright prohibition. A brand that shipped a comfrey "healing" salve or a high-strength BHA toner cleared for the EU can watch the same SKU refused at the Canadian border because an ingredient legal abroad is blacklisted at home.
Compliance teams see the pattern repeatedly: a screen at the brief stage costs nothing, while a reformulation after a 2,000-unit run costs a destroyed batch and a relabel. The gap between those two outcomes is usually one unchecked INCI name.
This piece gives you a self-checkable read of the plant ingredients brand teams ask about most often, each with the condition the list actually states, then sets Canada beside the EU and the US. The most expensive mistake is assuming EU clearance buys Canadian clearance. It does not.
TL;DR: Four names dominate Canadian screening questions, and they do not resolve the same way. The Symphytum genus is prohibited but Symphytum officinale is excepted — an exception now proposed for removal. Salicylic acid is capped at 2%. Furocoumarins are capped at 1 mg/kg in sun tanning products. Psoralea corylifolia and bakuchiol are not listed by name at all. Screen the listed substance, not the marketing story, before manufacturing — not after a retailer delisting.
The Hotlist itself is published by Health Canada and is the authoritative reference for prohibited and restricted substances in Canadian cosmetics. You query it directly by INCI name or CAS number, and the entry tells you whether an ingredient is out, capped, or conditional. The list itself: Health Canada's Cosmetic Ingredient Hotlist.
Four Plant Actives and How Each One Actually Reads
The four names below are the ones brand teams raise most often, and no two are treated alike. "Prohibited" means the ingredient cannot appear; "restricted" means it can, only inside the condition printed beside it. Two of the four are not on the list under their own name — a different answer from being cleared.
Key Takeaway: Three patterns, not one answer: the name is absent (bakuchiol, Psoralea), the plant is barred with one species excepted (comfrey), or the molecule is capped (furocoumarins, salicylic acid). Each demands different supplier evidence.
| Ingredient | Hotlist entry | Stated condition | Compliant alternative |
|---|---|---|---|
| Comfrey (Symphytum spp.) | Prohibited, with Symphytum officinale excepted | Symphytum spp., with the exception of Symphytum officinale — the exception is proposed for removal |
Synthesized allantoin, if you would rather stop tracking the exception |
| Furocoumarins | Restricted | Furocoumarins, except for naturally occurring in plant extracts — 1 mg/kg (1 ppm) in sun tanning products. Proposed: barred as an intentionally added ingredient, and the 1 ppm cap extended to every leave-on product when naturally occurring |
Non-phototoxic actives; no direct botanical substitute |
| Salicylic acid (BHA) | Restricted | Maximum concentration permitted: 2% | Reformulate below 2%, or move to a rinse-off vehicle |
| Psoralea corylifolia (Babchi) / Bakuchiol | Not listed by name | Neither appears under its own name; the furocoumarin entry governs the extract's impurity profile | A verified low-furocoumarin isolate, with the test result to match |
Symphytum sits on the prohibited list because the plant carries pyrrolizidine alkaloids — echimidine and lasiocarpine among them — that are hepatotoxic and potentially carcinogenic. The entry is not a blanket ban. It reads Symphytum spp., with the exception of Symphytum officinale, so the species most often used in cosmetics has sat outside the prohibition since the entry was added in December 2004 — the Hotlist changes log records Symphytum spp., with the exception of Symphytum officinale under Items Added that month. That exception is now proposed for removal: the consultation on the proposed Hotlist update opened on 19 November 2025, closed on 17 February 2026, and the final wording has not been published. A brand screening a comfrey extract today is not reading a settled rule. It is reading a window that has not closed yet.
Psoralea corylifolia, the Babchi seed that is also the natural source of bakuchiol, is the ingredient most often described as banned in Canada. It does not appear on the Hotlist under that name, and neither does bakuchiol. What the list regulates is the molecule behind the concern: an entry for Furocoumarins, except for naturally occurring in plant extracts, restricted to a maximum of 1 mg/kg (1 ppm) in sun tanning products. Psoralens are why a Babchi-derived extract is hard to place — not a Latin name printed on a government page. The consultation proposes tightening that condition: no intentional addition of furocoumarins, and the 1 ppm cap stretched to every leave-on product rather than sun tanning products alone.
Salicylic acid is the one that surprises K-beauty and "clean" brands. Derived from willow bark and used as a BHA, it sits on the restricted list with a maximum concentration permitted of 2%. That ceiling is higher than the rhetoric suggests and lower than some hero toners assume. The fix is a lower percentage or a rinse-off vehicle, not a fight with the regulator.
Bakuchiol clears Canadian screening by absence. It has no entry of its own, so the question shifts from "is it listed?" to "what is in the drum?" An extract standardized to a high bakuchiol content can still carry the very furocoumarins the Hotlist caps — which is why a furocoumarin test result matters more than a purity claim on a spec sheet.
Hotlist vs EU 1223/2009 vs FDA: Where the Three Systems Diverge
A single formula rarely clears all three markets unchanged. The table below shows how the same ingredient lands in Canada, the EU and the US.
Key Takeaway: An ingredient cleared in the EU is not automatically cleared in Canada — retinol is the cleanest proof, because the two systems cap it at different numbers for different product types.
| Ingredient | Canada (Hotlist) | EU (Reg. 1223/2009) | US (FDA) |
|---|---|---|---|
| Hydroquinone | Restricted: 0.3% in oxidizing hair dyes, 0.1% in nail products and eyelash/eyebrow adhesives | Limited to 0.3%, nail products only | Prohibited in OTC skin bleach; prescription only |
| Salicylic acid | Restricted: 2% maximum | Up to 2% leave-on, 3% rinse-off (warnings required) | OTC acne up to 2%; cosmetic caps apply |
| Retinol (Vitamin A) | 0.2% total retinol equivalents in full-body leave-on; 1.0% in other cosmetics | 0.3% facial / 0.05% body (retinol equivalent) | No formal cosmetic limit; MoCRA safety substantiation applies |
| Sunscreen UV filters | Not a cosmetic — NHP / drug pathway | Authorized under Annex of 1223/2009 | OTC monograph / GRASE list |
Hydroquinone hides the widest gap between reputation and permitted use. Canada restricts it to 0.3% in oxidizing hair dyes and 0.1% in nail products and eyelash or eyebrow adhesives — a set of permitted uses that has nothing to do with the skin-lightening products the ingredient is famous for. The EU confines it to nail products at 0.3%, and the US routes it to prescription.
Salicylic acid reads as a near-miss rather than a divergence. Canada and the EU both land on 2% for leave-on use, and the US OTC acne monograph matches at 2%, so a lower-ceiling story does not hold. The EU's additional 3% rinse-off allowance is where the two written rules part. Retinol diverges more usefully: Canada allows 0.2% total retinol equivalents in full-body leave-on and 1.0% in other cosmetics, while the EU works to 0.3% facial and 0.05% body.
Sunscreen breaks the comparison. Canada routes UV-filter products through the Natural Health Products or drug pathway, not the cosmetic file. The EU authorizes filters under Annex of Regulation (EC) No 1223/2009, and the US runs an OTC monograph system. If your line spans markets, build a per-market version matrix rather than one global formula.
Registration and listing rhythms differ per market, packaging rules move on their own clock, and a sunscreen SKU leaves the cosmetic file behind in both Canada and the US. None of that shows up in a formula review.
Beyond the Plant Actives: What Is Proposed and What Is Settled
Two clocks run against every new SKU, and only one of them is waiting for the law to move.
Key Takeaway: Sort these four by status before you plan. Settled: fragrance allergen disclosure at 81 substances, the 10-day CNF window, bilingual labelling. Still in draft: adding PHMB to the restricted list, and tightening the furocoumarin condition.
Fragrance allergen disclosure moves from 24 substances to 81. The change is registered, not proposed: SOR/2024-63 incorporates the EU's Annex III fragrance-allergen list by ambulatory reference — 81 entries today, up from the original 24 — and it has been in force on this point since 12 April 2026 — the second anniversary of registration. New products had to comply by 31 July 2026; existing stock sells through until 31 July 2028. Disclosure bites above 0.01% in rinse-off products and 0.001% in leave-on products, so a fragrance "mix" certificate without the full substance breakdown no longer covers you — pull the complete allergen declaration from your supplier. The Canada Gazette notice for SOR/2024-63 carries the thresholds and the RIAS behind the list.
Preservative screening runs on a wider net than the Hotlist alone. Polyhexamethylene biguanide is the example to keep straight: the spray and leave-on restrictions brands cite come from the EU regulation, not from a Canadian entry — there is no entry for it under that name or any synonym. That is proposed to change: the same consultation would add Polyaminopropyl Biguanide (also listed as Polyhexamethylenebiguanide and PHMB) as a restricted entry, with spray and aerosol formulations prohibited and 0.2% proposed for other cosmetics. Until the final wording lands, the Canadian duty is the general safety obligation — the evidence burden sits on your supplier file, not on a printed limit.
The Cosmetic Notification Form (CNF) carries a short filing window. Section 30(1) of the Cosmetic Regulations requires the documents "at the latest 10 days after the manufacturer or importer first sells a cosmetic" — a 10-day clock from first sale, with no grace period. The Cosmetic Notification Form portal is where you submit, and it is free.
Filing is a notification, not an approval: there is no "cleared" stamp, but the regulator can request your Product Information File and act at any time. These duties sit under Canada's broader SOR/2024-63 modernization; read how SOR/2024-63 affects manufacturers.
Bilingual labelling (English / French) is the cost brands underestimate. Every claim, warning, and ingredient line must appear in both official languages. This is settled under the Food and Drugs Act, not a 2026 novelty — but it is where first-time Canada entrants burn budget.
One more thread: comfrey moves toward a full prohibition as the PA-risk route closes, and the deciding document is the consultation that ended in February 2026, not anything already printed on the list. The proposal is written down before it takes effect, so the version of the list you read matters.
A K-Beauty Brand's Canada Friction (Anonymous Industry Case)
The pattern below is drawn from desensitized trade accounts, not a named client.
Key Takeaway: A formula legal at home can be non-compliant in Canada. What it costs depends on when the gap surfaces.
One brand built its hero SKU on a K-beauty "glass skin" story around a high-strength BHA toner — salicylic acid at a concentration legal for leave-on toners at home. Before pitching a Canadian retailer, it ran the formula against the Hotlist and found the level exceeded the Canadian maximum of 2%. The remedy was a lower concentration or a rinse-off format. Because it surfaced early, the cost was a single revision.
The same brand had assumed its EU compliance file would carry weight in Canada. It did not — the two lists diverge on exactly the ingredient in its hero product. That assumption stalls Canada entry for otherwise export-ready brands.
If you are building a Canada-ready line from a blank formula, the Canadian skincare OEM regulations explain what a local-compliant manufacturer handles end to end. On a related note, squalane on the Canada Hotlist covers a specific ingredient brands often flag when screening.
How to Self-Check Your Formula Against the Hotlist
The screen takes an afternoon. Every later fix costs more.
Key Takeaway: Steps 2 to 4 are where formulas change; steps 1 and 5 catch the errors that only surface later, at the retailer.
- List every INCI name, not the marketing name. One botanical carries many synonyms, and the list is indexed by CAS number as well.
- Cross-check each INCI against the Health Canada Cosmetic Ingredient Hotlist. Note whether each hit is prohibited or restricted, and the exact condition.
- Confirm concentration and format. A restricted ingredient may be fine at 1% in a rinse-off but banned at 2% in a leave-on. Match the limit to your vehicle.
- Pull supplier certificates that address the specific restriction. PAs for any Symphytum extract, furocoumarins for Babchi-derived material, the 81-allergen breakdown for fragrance. A generic CoA will not defend you.
- Confirm bilingual labelling and file the CNF within 10 days of first sale. The notification goes to Health Canada through its online portal.
A blacklisted plant ingredient is rarely a surprise in hindsight. The Hotlist is public and the conditions are written down. The surprise arrives from a retailer delisting notice instead of a formula screen — which is why Custom OEM/ODM programmes run the check before tooling.
If your line is heading to Canada, the cheapest compliance work you will ever do is the screen before the batch is made. For brands building a Canada-ready formulation from scratch, our Canadian compliance OEM service runs the Hotlist screen, bilingual labelling, and CNF filing as part of a custom run above 2,000 units. Finding out early costs a formula edit; finding out at the border costs the batch.
