Allergen Declaration for Perfume and Eau de Toilette

Perfume is the one product category where the allergen disclosure question basically flips on its head. With a lotion or a shampoo, you're often checking whether a given allergen clears the threshold at all. With a fine fragrance at 15 to 30% fragrance concentrate, the real question becomes which allergens don't need declaring, because at that dosage, almost everything in the blend does.

Why perfume is different from every other product type

Most cosmetics carry fragrance at a small fraction of the formula, often under 1%. A lotion might use 0.5% fragrance oil. A shampoo might use 1%. At those dosages, individual allergens within the fragrance blend often stay under the leave-on disclosure threshold of 0.001% (10 ppm), unless that particular allergen is a major constituent of the blend.

Perfume and eau de toilette work completely differently. Fragrance concentrate in fine fragrance products commonly runs anywhere from around 15% up to 30% or more of the total formula, since fragrance isn't an additive here, it's the entire point of the product. That order-of-magnitude difference means allergens present at even a small percentage within the fragrance concentrate itself can easily clear the finished-product threshold.

Running the math

Take a fragrance concentrate that's 3% linalool by weight, used at a 20% concentration in an eau de toilette. The finished-product concentration of linalool is 0.6%, which is 6,000 ppm, wildly above the leave-on threshold of 10 ppm. Compare that to the same fragrance concentrate used at 1% in a body lotion: finished-product linalool concentration drops to 0.03%, still well above the threshold, but you can see how the multiplier compounds. In a fine fragrance, it's not unusual for six, eight, or more individual allergens in a single blend to each independently clear the disclosure threshold.

This means for perfume specifically, you should assume most or all common allergens present in your fragrance concentrate need individual declaration, and treat the exercise as confirming which ones you can leave off, rather than assuming most will be excluded by default.

What you actually need from your fragrance house

A full allergen breakdown of the concentrate is non-negotiable for a fine fragrance filing. You need, at minimum:

• A list of every regulated allergen present in the compound
• The percentage of each within the concentrate
• Confirmation of which regulatory lists each allergen falls under, since Canada's List 1 and List 2 don't necessarily match every other market's allergen set exactly

Fragrance houses that supply fine fragrance concentrates are generally used to providing this, since IFRA-certified suppliers already track allergen content for other markets. If your supplier is reluctant to share a breakdown, treat that as a real blocker to filing correctly, not a formality you can skip.

The two Canadian deadlines, and why perfume feels them first

List 1, the original fragrance allergen set, becomes mandatory on the CNF and the label on April 12, 2026. List 2, an expanded set aligned with international lists, becomes mandatory August 1, 2026. Because fine fragrance products run such high fragrance concentrations, they're the product category most likely to have several allergens from both lists clearing threshold simultaneously. A lotion maker might find they have zero or one declarable allergen. A perfume maker is more likely to be managing five, seven, or more across both lists.

A short table to frame it

Product type	Typical fragrance concentration	Allergens typically clearing threshold	Practical takeaway
Body lotion	0.3 to 1%	Usually just the major constituents of the blend	Check each, expect a handful to clear
Shampoo (rinse-off)	0.5 to 1.5%	Fewer, since rinse-off threshold is 10x higher	Check each against the 100 ppm rinse-off line
Eau de toilette	8 to 15%	Most significant constituents of the blend	Assume most will need declaring, confirm which don't
Perfume / parfum	15 to 30%+	Nearly all significant constituents	Plan your label layout around a longer allergen list from the start

Practical label planning

Given how many allergens are likely to clear threshold in a fine fragrance, it's worth planning label real estate for a longer ingredient declaration from the start of your packaging design, rather than finalizing bottle art around a short ingredient list and then discovering you need room for six additional allergen names. This is a genuinely common last-minute scramble for indie perfume brands who assumed "just a few drops of oil" would keep the label simple.

Getting the concentrate math right across a full allergen list, especially when you're multiplying several allergen percentages by your fragrance load, is exactly the kind of repetitive, error-prone calculation Cosmetic Comply automates, carrying the percentages through from your fragrance house's breakdown to a finished list of what needs to appear on your CNF and label before either April or August deadline arrives.
