Notifying an AHA or BHA Exfoliant Without Drug Claims

Glycolic acid toners and salicylic acid exfoliants are two of the most popular categories a small skincare brand launches, and also two of the easiest to accidentally turn into an unapproved drug with one bad line of marketing copy. The chemistry is straightforward. The labeling is where people trip.

Filing the formula itself

An AHA (alpha hydroxy acid, typically glycolic or lactic acid) or BHA (beta hydroxy acid, typically salicylic acid) exfoliant notifies in Canada the same way any other cosmetic does. You file a Cosmetic Notification Form through the Cosmetic Notification System within 10 days of first sale, listing every ingredient by INCI name with its concentration or a concentration range, including the acid itself. You get back a Cosmetic Notification (CN) number.

The acids themselves sit on Canada's Cosmetic Ingredient Hotlist with concentration and use conditions attached, so the exfoliant's formula needs to be checked against those limits before you file, not after a customer complaint forces the question. Free acid content, not just total acid percentage, tends to be the detail people miss, since a formula's pH determines how much of the acid is actually active versus buffered.

Where the claim, not the chemistry, decides the category

Here is the part that actually determines whether Health Canada treats your product as a cosmetic or something that needs drug-level review: what you say it does.

Cosmetic-appropriate language for an exfoliant tends to describe surface effects and appearance:

• Exfoliates and smooths the skin's surface
• Improves the look of texture and tone
• Reduces the appearance of fine lines
• Helps refine pores

Language that pushes toward a drug claim tends to describe treating a medical condition or altering skin function beyond appearance:

• Treats acne
• Clears breakouts caused by bacteria
• Penetrates and dissolves sebum to cure blemishes
• Reduces inflammation associated with a skin condition

The same 2% salicylic acid toner can be marketed two completely different ways, and only one of those ways keeps it a cosmetic notification instead of triggering drug regulation. This is not unique to Canada. In the US, an acne-treatment claim on a BHA product is a well-known trigger for OTC drug status, since acne treatment sits in drug territory regardless of the active ingredient's cosmetic pedigree.

A side-by-side on wording

Claim style	Category outcome	Example wording
Appearance and texture	Cosmetic	"Smooths rough texture, brightens the look of dull skin"
Exfoliation mechanism, no medical outcome	Cosmetic	"Gently exfoliates to reveal softer skin"
Named skin condition	Drug	"Clears acne"
Therapeutic or curative language	Drug	"Treats blemishes and reduces breakouts"

Practical formulating notes

A few things worth building into your process before the first CNF filing:

• Confirm the free acid percentage at your working pH, not just the raw acid input percentage, since the Hotlist conditions are tied to what is actually active in the finished product
• Keep a sun-sensitivity warning on the label where applicable, since AHAs in particular increase photosensitivity
• If your exfoliant includes an essential oil for scent, check it against the upcoming fragrance allergen disclosure rules in Canada, since citrus-derived exfoliating toners often carry limonene naturally
• Write your marketing copy and your ingredient deck in the same sitting, so nobody on the team accidentally slaps an acne claim on a product that was formulated and filed as a cosmetic

Cosmetic Comply matches your AHA or BHA formula's ingredients to INCI and CAS, checks the acid concentrations against the Hotlist, and has a compliance reviewer confirm the result before filing, so the chemistry side of the notification is handled while you focus on getting the claim language right.
