Triclosan: The Hotlist Limit and the Drug Line

Triclosan is one of those ingredients that trips people up twice. First on the concentration limit, then on the claim you put next to it. You can get the percentage right and still land in trouble because of what your label says the product does.

What triclosan is doing in your formula

Triclosan is an antimicrobial agent that shows up in deodorants, some soaps, and a handful of other personal care products where a maker wants preservation or odor control. It's been used for decades, and it's also been under increasing scrutiny for exactly that long, which is why it sits on Canada's Cosmetic Ingredient Hotlist as a restricted substance rather than a flatly prohibited one.

Restricted, on the Hotlist, means Health Canada allows the ingredient up to a defined concentration, in defined product types, sometimes with additional conditions attached. It's not a free pass and it's not a ban, it's a specific lane you have to stay inside.

Why the exact limit isn't something to guess at

Hotlist entries change. Triclosan's permitted concentration and the product categories it applies to are the kind of detail that gets refined as new safety data comes in, so quoting a specific percentage in a blog post risks being wrong by the time you read it. The right move is always to pull the current Hotlist entry directly before you finalize a formula, not to rely on a number you saw somewhere else, including here.

What you can rely on as a stable concept:

• Triclosan has a maximum permitted concentration in Canada, and it varies by product type.
• Some product categories may not permit it at all.
• The Hotlist is not a static document. It gets updated, and an ingredient's status can tighten over time.

Where the claim comes in

Here's the part that catches makers who've already done their concentration homework. A cosmetic in Canada is defined by what it's used for and what it claims to do, not just its ingredient list. Soap sold purely on a cleansing claim can be treated differently from a cosmetic. But the moment you add an antibacterial or antiseptic claim, killing germs, reducing bacteria, medical-sounding language, you're no longer describing a cosmetic function. You're describing a drug function.

That distinction matters because triclosan sitting in a formula at a Hotlist-compliant concentration is fine for a cosmetic notification. Triclosan in a formula you're marketing as "kills 99.9% of bacteria" is a different regulatory animal entirely, and it doesn't get fixed by adjusting the percentage. It gets fixed by either dropping the claim or accepting that the product needs to go through drug regulatory channels instead of a cosmetic notification.

A simple table to keep the two issues separate

Question	What it controls
Is triclosan within the Hotlist concentration limit for this product type?	Whether the ingredient itself is compliant
Does the label make an antibacterial, antiseptic, or medicinal claim?	Whether the product is still a cosmetic at all
Is the product a soap sold only on a cleansing claim?	Whether it may be treated outside standard cosmetic rules

You can pass the first row and fail the second. Concentration compliance doesn't rescue a product from a claim that reclassifies it.

What to do before you notify

If you're using triclosan and planning to file a Cosmetic Notification Form, check the current Hotlist entry for the exact permitted concentration and any product-type restrictions, then separately audit your own label copy and marketing language for anything that reads as a drug claim. These are two different reviews and both need a clean pass.

If your product genuinely functions as an antibacterial and you want to make that claim honestly, that's a legitimate business decision, it just means routing the product through the correct regulatory pathway instead of a cosmetic notification. Trying to make a drug claim stick to a cosmetic filing doesn't work, and it's the kind of thing that surfaces during a review rather than getting ignored.

Cosmetic Comply's ingredient screening flags restricted substances like triclosan against the current Hotlist automatically and scores your confidence on the match, but it can't read your marketing copy for you. That half of the check is still on you, every time you touch the label.
