Why Your Fragrance SDS Just Says Parfum and What to Do

You ask your fragrance supplier for a full ingredient breakdown, and what comes back is a safety data sheet with a single line under composition: Parfum. That is it. No list of the forty-odd aroma compounds actually blended into that oil. It feels like a stonewall, and a lot of makers assume the supplier is hiding something shady. Usually they are not. Usually this is just how fragrance disclosure has always worked, and there is a specific document you need to ask for instead.

Why "Parfum" is allowed to be the whole answer

Fragrance formulas are treated as trade secrets across the industry, largely because a finished fragrance blend can represent real intellectual property, sometimes decades of formulation work, and disclosing the full recipe would let anyone reverse-engineer it. So the convention that developed lets fragrance be declared as a single umbrella term, Parfum, without breaking out every individual aroma chemical, similar to how a cola company does not have to disclose its exact flavor formula.

An SDS has 16 standard sections, and section 3 is where composition information lives. For a fragrance blend, seeing "Parfum" in section 3 with no further breakdown is normal, expected, and not a sign your supplier is being difficult. It reflects the same trade-secret logic that applies industry-wide.

But allergen disclosure is a separate carve-out

Here is the part that trips people up: the trade-secret protection covers the overall fragrance formula, not specific allergen components once they cross a disclosure threshold. Fragrance allergens like Limonene, Linalool, Citronellol, Geraniol, Eugenol, and Coumarin have their own disclosure requirement layered on top of the general "Parfum" convention. In Canada, disclosure kicks in above 0.001 percent (10 ppm) in leave-on products and above 0.01 percent (100 ppm) in rinse-off products. A supplier can protect their overall formula as a trade secret while still being expected to tell you which specific allergens are present above those thresholds and at roughly what level.

This is why the SDS alone often is not enough. A generic SDS is built for workplace safety and hazard communication, not for the granular allergen percentage data a cosmetic notification needs. What you actually want is an allergen declaration or allergen statement specific to fragrance and cosmetic use, which reputable fragrance houses do provide on request, separate from the standard SDS.

What to actually ask your supplier for

Instead of pushing back on the SDS itself, which is doing exactly what it is supposed to do, ask specifically for:

• A fragrance allergen declaration listing which of the recognized allergens are present in the blend and their approximate concentrations.
• Confirmation of the blend's total usage recommendation, so you can calculate real finished-product concentrations.
• IFRA compliance documentation if available, since IFRA certificates often accompany allergen breakdowns as a package.

Most established fragrance suppliers have this documentation ready to send, because cosmetic makers ask for it constantly. If a supplier genuinely cannot produce any allergen data at all, that is a more legitimate reason for concern than the plain SDS looking sparse.

Doing the math once you have the numbers

Say your supplier's allergen declaration says their fragrance blend contains linalool at roughly 3 percent of the blend, and you use that fragrance oil at 0.5 percent in a leave-on lotion. Multiply those two figures: 0.5 percent times 3 percent gives 0.015 percent linalool in your finished product, well above the 0.001 percent leave-on threshold, meaning it needs to be named specifically as an allergen, not left buried inside "Parfum."

Document	What it tells you	What it usually will not tell you
Standard SDS	Hazard, handling, general composition	Specific allergen breakdown or percentages
Allergen declaration	Which allergens are present and roughly how much	The full proprietary fragrance formula
IFRA certificate	Compliance with international fragrance safety limits	Finished-product concentration in your specific recipe

Getting from supplier paperwork to a real filing

Chasing down allergen declarations from every fragrance supplier you use, then doing the multiplication for every product in your line, adds up fast once you have more than a couple of scents in rotation. This is a good chunk of what Cosmetic Comply handles for you: it takes the supplier data you feed it, expands the blend into its real components, carries the percentages through to your finished product, and flags which allergens cross the disclosure line for your specific formula, so you are not left squinting at a one-word SDS entry wondering what you are actually allowed to sell.
