Do Cold Process Soap Makers Need a Cosmetic Notification

This question comes up in every soap maker forum eventually, usually phrased as "wait, do I actually need to file this?" The honest answer is: it depends entirely on what your label and marketing say, not on the fact that you made it with lye and oils in a crockpot.

The true soap exemption, and how narrow it is

Health Canada, like several regulators, treats "true soap" differently from a cosmetic. True soap means an alkali salt of a fatty acid, essentially the classic saponification reaction of oil and lye, sold with nothing but a cleansing claim. Wash your hands, clean your body, that's it. If that's genuinely your entire label and marketing, you may be sitting outside cosmetic regulation entirely, closer to how a basic detergent bar is treated.

But that exemption is narrower than most makers assume, and it evaporates the moment you make a cosmetic claim.

The claim is what flips the switch, not the process

Say "moisturizing," "nourishing," "softens skin," "reduces breakouts," "anti-aging," or anything describing a benefit beyond cleansing, and your bar soap is now a cosmetic in the eyes of the regulator, regardless of how traditional the cold process method is. This is true even if the soap is otherwise identical, same oils, same lye, same cure time. The chemistry doesn't change. The legal category does, because the category is defined by what you claim the product does.

Most artisan soap makers make at least one of these claims, often without thinking of it as a regulatory trigger:

• "Moisturizing shea butter bar"
• "Helps calm sensitive skin"
• "Nourishes with goat milk"
• "Softening oatmeal soap"

Every one of those is a cosmetic claim. The soap itself might be identical to a plain, unscented bar sold purely as "soap for washing," but the labeling has moved it into cosmetic territory.

What "being a cosmetic" actually requires

Once your bar soap is a cosmetic in Canada, the same rules apply as any other cosmetic product: you file a Cosmetic Notification Form through the Cosmetic Notification System within 10 days of first sale, listing every ingredient by INCI name with concentration or a concentration range. This is a notification, not a pre-approval process, Health Canada isn't signing off before you sell, but the filing still has to happen and has to be accurate. You'll receive a Cosmetic Notification (CN) number once it's submitted.

Your ingredients also get checked against the Cosmetic Ingredient Hotlist, and your label needs to be bilingual, English and French, same as any other cosmetic sold in Canada.

Fragrance and essential oils complicate this further

Most cold process soap contains fragrance oils or essential oils, and many of those carry allergens that need disclosure. Common ones include limonene, linalool, citronellol, geraniol, eugenol, and coumarin, all of which occur naturally in a wide range of essential oils used in soap making, lavender, citrus, clove, and more. Health Canada's fragrance allergen disclosure rules apply differently depending on whether the product is leave-on or rinse-off. Soap is rinse-off, so the threshold that triggers mandatory disclosure is higher (above 0.01%, or 100 ppm) than it would be for a leave-on lotion (above 0.001%, or 10 ppm). List 1 becomes mandatory on the CNF and label on April 12, 2026, and List 2, an expanded set, becomes mandatory August 1, 2026. If your soap uses essential oils, it's worth checking your fragrance or oil supplier's documentation against both lists now rather than waiting.

A practical way to check your own product

Ask yourself these three questions honestly:

1. Does my label make any claim beyond cleansing? (moisturizing, gentle, nourishing, anti-anything)
2. Do I use fragrance oils or essential oils that could carry allergens?
3. Would a customer reasonably expect a skin benefit, not just cleanliness, from reading my packaging?

If you answered yes to any of these, you're almost certainly in cosmetic territory and need to file.

Where this leaves most artisan makers

In practice, the overwhelming majority of small-batch cold process soap sold at markets and online carries at least one benefit claim, because that's how soap gets sold today. Plain, unscented, no-claims soap is a genuinely small niche. If that's not your product, budget for the CNF process as part of launching, not as an afterthought once a customer or retailer asks for your CN number.

Cosmetic Comply is built with exactly this kind of small-batch maker in mind, it takes your ingredient list, maps it to INCI and CAS, expands any supplier blends, screens against the Hotlist, and files the CNF once a real compliance reviewer has checked it. It's meant to be affordable enough that a soap maker selling at a Saturday market can use it the same way a larger cosmetic brand would.

If in doubt about your own label's wording, the safest move is to assume you're a cosmetic and file. Walking that back later is a lot more paperwork than filing correctly the first time.
