Getting Ingredient Names Right on Your CNF Using INCI

If your recipe card says "vitamin E oil" and "emulsifying wax NF," neither of those phrases belongs on a Cosmetic Notification Form, and submitting them as written is one of the most common reasons a filing bounces back or sits stuck in review longer than it should.

Why the CNF insists on INCI

INCI, the International Nomenclature of Cosmetic Ingredients, exists precisely so that a single naming standard covers every cosmetic ingredient regardless of which supplier sold it, which country it was formulated in, or what a marketing team decided to call it on the jar. Water is Aqua under INCI everywhere. That consistency is what lets Health Canada's Cosmetic Notification System process filings at scale and cross-check ingredients against the Cosmetic Ingredient Hotlist without needing to interpret a hundred different trade names.

The CNF is a notification, filed through the Cosmetic Notification System within 10 days of first sale, and it results in a Cosmetic Notification, or CN, number. Notification is not pre-approval, but the system still depends on the ingredient data being entered in the format it expects. Trade names and vague descriptors don't map cleanly to that format, which is where delays start.

Where mismatches actually happen

Trade names standing in for INCI. "Vitamin E oil" needs to be represented by its actual INCI name, most commonly Tocopherol, sometimes as a blend with other tocopherol isomers depending on the specific product used. "Emulsifying wax NF" is a blend, not a single ingredient, and its components need to be broken out.

Supplier blends listed as one line. A single raw material purchased under one name is often several INCI-named components combined at the supplier's factory. If you list the blend by its trade name and stop there, you haven't actually told Health Canada what's in the product. You need to expand the blend into its individual components and calculate the real concentration of each one in your finished product, which means multiplying the component's percentage within the blend by how much of the blend you used.

Common names for botanicals with no standard match. Some botanical extracts genuinely have no assigned CAS number, and that's fine, the INCI name still applies and is what gets used. But a maker writing "chamomile" instead of the correct INCI form for the extract they actually used, which varies depending on whether it's an oil, a water extract, or a specific plant part, creates ambiguity that slows review.

Fragrance and essential oil constituents. As Canada's fragrance allergen disclosure rules phase in, with List 1 mandatory April 12, 2026 and List 2 mandatory August 1, 2026, allergens like Limonene, Linalool, and Eugenol need to be identified by name where they're present above the relevant threshold, not folded silently into a generic "fragrance" or "parfum" entry.

A quick reference for common mismatches

What's on the recipe card	What belongs on the CNF
Vitamin E oil	Tocopherol (or specific isomer, per supplier data)
Vegetable glycerin	Glycerin
Emulsifying wax NF	Expanded into its individual INCI components
Coconut oil	Cocos Nucifera Oil
Lye (in soap context)	Sodium Hydroxide, or Potassium Hydroxide
Preservative blend (trade name)	Expanded into individual preservative INCI names with adjusted percentages

Concentration and range reporting

Beyond just naming the ingredient correctly, the CNF expects concentration or a concentration range for each one. This is another spot where blend expansion matters: if your finished product contains 2 percent of a preservative blend, and that blend is documented by the supplier as 10 percent phenoxyethanol, the real concentration of phenoxyethanol in your product is 0.2 percent, not 2 percent. Filing the blend's own percentage instead of the calculated component percentage is a subtle error that's easy to make and easy for a reviewer to catch.

Why this is worth getting right the first time

An incorrect or incomplete ingredient name doesn't necessarily stop your product from being notified, since notification isn't a gatekeeping approval step, but it does create a filing that doesn't accurately represent what's actually in your product. That gap can surface later: during a compliance review, if a retailer asks for your documentation, or if you ever need to file an amendment and the baseline record is already wrong.

This translation step, going from a recipe card to correctly expanded INCI names with accurate percentages, is exactly the piece Cosmetic Comply automates. You give it your ingredient list as you actually understand it, and it maps every entry to its INCI name and CAS number, expands supplier blends into real components, carries the math through, and has a compliance reviewer check the result before anything gets filed.
