Phenoxyethanol: Its Limit and Status on the Hotlist

Ask ten indie makers whether phenoxyethanol is banned in Canada and you'll get a confident "yes" from at least half of them. It's one of the most persistent myths in the small-batch skincare world, usually inherited from a Facebook group post that misread a restriction as a prohibition. It's worth clearing up properly, because phenoxyethanol is one of the most widely used preservatives in cosmetics for good reason: broad-spectrum activity, decent stability, and a long track record.

Restricted is not the same as prohibited

The Hotlist has two categories and they behave completely differently. A prohibited substance cannot appear in a cosmetic sold in Canada, period. A restricted substance can be used, but only under specific conditions, usually a maximum concentration in the finished product, sometimes limited to certain product types. Phenoxyethanol sits in the restricted category with a concentration ceiling. It is legal to use, it is legal to sell products containing it, and it shows up in a huge share of the leave-on and rinse-off products already notified through the Cosmetic Notification System.

The myth almost certainly comes from phenoxyethanol's more complicated history in a couple of other markets, where at various points its use in specific product types (like products intended for very young children) was tightened. That's a different regulator with a different rule. Health Canada's Hotlist entry for phenoxyethanol is a concentration limit, not a ban.

Where the limit actually applies

The ceiling is set against the finished product as it reaches the consumer, not the raw preservative or a supplier's preservative blend. This matters because phenoxyethanol rarely arrives in a formula on its own. It's frequently sold pre-blended with other preservatives such as ethylhexylglycerin, caprylyl glycol, or a small amount of an organic acid, under a trade name that gives no hint of the actual phenoxyethanol content unless you check the supplier's technical data sheet or SDS section 3.

If your preservative blend is 90% phenoxyethanol and you're using it at 1% of your total formula, your actual phenoxyethanol concentration is:

0.90 x 1% = 0.9%

That's the number that needs to sit under the Hotlist ceiling, not the "1%" you wrote on your batch sheet as the blend's use rate.

Why the finished-concentration distinction trips people up

What gets checked	What it should be checked against
Blend's use rate on the batch sheet	Not the compliance-relevant number
Trade name percentage claim	Often vague or blend-specific, not the pure ingredient
True phenoxyethanol concentration in finished product	This is what the Hotlist limit is measured against

A maker who never opens the SDS or technical data sheet for their preservative blend is essentially filing a notification without knowing their real concentration. That's not a Hotlist violation by itself, but it's the kind of gap that turns into one the moment you increase your preservative blend's use rate for a new product without rechecking the math.

What to put on your CNF and label

Phenoxyethanol goes on the ingredient list by its INCI name, which is simply "Phenoxyethanol," alongside every other component of the blend it arrived in, each listed separately by its own INCI name at its own true concentration. Trade names for the blend never appear on the notification or the label. If your supplier's blend includes a fragrance-relevant component, unlikely for a phenoxyethanol blend but worth checking on any multi-component additive, that component gets evaluated on its own terms too.

The practical takeaway

Phenoxyethanol is fine to use in Canada, well within its Hotlist limit, in the vast majority of ordinary formulations. The actual risk isn't the ingredient, it's makers assuming a restriction is a ban and either avoiding a perfectly good preservative out of unfounded fear, or worse, assuming "it's legal" means "there's no limit to check" and skipping the concentration math on a blend they've never actually calculated through.

If you want that math done for you rather than trusted to memory, Cosmetic Comply pulls the real component percentages out of your ingredient list, including supplier blends, and checks each one against the current Hotlist limit before your notification goes in.
