Why Listing Parfum Alone No Longer Covers You

For years, "Parfum" was the polite way of saying "trust us, it smells nice, don't ask what's in it." One line covered dozens of fragrance components, and that was allowed because fragrance formulas were treated as proprietary. That era is ending in Canada, on a specific timeline, and it's worth understanding why the shift happened and not just that it happened.

The problem parfum was hiding

A fragrance oil or compound can legitimately contain dozens of individual chemical components. Some of those components, including ones that occur completely naturally in essential oils, are known to cause allergic skin reactions in a meaningful subset of people. Limonene, linalool, citronellol, geraniol, eugenol, and coumarin are common examples, and they show up constantly in citrus oils, lavender, rose-type fragrances, clove-derived scents, and more.

The trouble is that "Parfum" as a single umbrella term gave consumers with known sensitivities no way to check whether a specific allergen they react to was actually present. Someone allergic to linalool couldn't look at an ingredient list and know if the lavender-scented lotion in front of them contained it, because it was buried inside one opaque word.

What's actually changing

Canada is moving to itemized allergen disclosure on both the Cosmetic Notification Form and the product label, on a two-part schedule:

• List 1 (the original, narrower fragrance allergen set) becomes mandatory on April 12, 2026.
• List 2 (an expanded set aligned with international lists) becomes mandatory on August 1, 2026.

Once a substance on the applicable list is present above the disclosure threshold, it needs to be named individually, both on the CNF and on the label, rather than folded silently into a generic "Parfum" entry.

The thresholds that trigger disclosure

The trigger isn't about how much fragrance oil you added, it's about the concentration of the specific allergenic component in the finished product:

Product type	Disclosure threshold
Leave-on	Above 0.001% (10 ppm)
Rinse-off	Above 0.01% (100 ppm)

These are low numbers. A fragrance oil doesn't need to be a large percentage of your formula for an individual allergen inside it to cross the threshold, especially in a leave-on product where the bar is ten times lower than for rinse-off.

Why this catches natural formulators off guard

A lot of makers assume this is a synthetic-fragrance problem and that using essential oils sidesteps it. It doesn't. Essential oils are frequently where these allergens come from in the first place. Lavender essential oil naturally contains linalool. Citrus oils are a common source of limonene. Clove oil contains eugenol. If your "unscented, all-natural" positioning is built on essential oils rather than a synthetic fragrance compound, you may still be carrying disclosable allergens, and you need your supplier's documentation to show the actual component percentages, not just "100% pure essential oil" on the label.

What you need from your suppliers now

1. Ask any fragrance or essential oil supplier for a full allergen breakdown of their product, not just a generic compliance statement.
2. Get the percentage of each disclosable allergen within the fragrance or oil itself.
3. Multiply that percentage by your use level in the finished formula, the same math you'd do for any supplier blend.
4. Compare each result against the leave-on or rinse-off threshold that applies to your product.

If a supplier can't or won't give you that breakdown, that's worth treating as a real gap, not a formality, because you'll need the data regardless of whether you fill it in yourself or lean on a tool to do it.

Getting ahead of the deadline

If you're formulating something scented now, whether it launches before or after these dates, it's worth doing the allergen math up front rather than scrambling when List 1 becomes mandatory. Reformulating a fragrance load after the fact, or discovering post-launch that you need to amend a filing to add itemized allergens, is more work than getting the breakdown right the first time.

Cosmetic Comply tracks these thresholds and the List 1 and List 2 schedule as part of screening your formula, so when you enter a fragrance or essential oil ingredient, it flags which components need individual disclosure based on your product type and use level, rather than leaving you to work out the ppm math on your own.
