Fragrance Is the Loophole: Moisturizers, Lotions, and 'Parfum'

Flip over almost any lotion at the drugstore and read the ingredient list. Somewhere after the water and the glycerin sits a single word: "fragrance." Maybe "parfum," if the brand is feeling French. That word is not an ingredient. It's a curtain, and US law says nobody has to show you what's behind it.

One word, as many chemicals as the perfumer wants

The Fair Packaging and Labeling Act, the 1960s law behind the modern ingredient list, requires cosmetics to declare what's in the bottle. It carries one famous exception: the rules can't be used to force companies to give up trade secrets, and FDA regulations treat scent blends as exactly that. Under Title 21 of the Code of Federal Regulations, a fragrance mixture can appear on the label as the single word "fragrance," no matter how many individual chemicals went into it. Dozens is routine.

For decades, one of the workhorses behind the curtain was diethyl phthalate, or DEP, a solvent and fixative that makes scent last. When a coalition of health groups paid a lab to test 72 name-brand products in 2002, phthalates turned up in nearly three quarters of them without appearing on a single label. Industry has since backed away from DEP, and CDC biomonitoring shows Americans' exposure falling. Notice, though, what you could have done about any of this at the shelf: nothing. The label said "fragrance" the whole time, before, during, and after.

Congress finally moved in 2022. The Modernization of Cosmetics Regulation Act directs the FDA to require fragrance allergens to be named on labels, something the EU has required for years. Those rules are still being written. Until they arrive, one word covers everything.

Why your dermatologist keeps repeating herself

Set the slow-poison scenarios aside for a minute, because the documented, everyday harm from fragrance is much less cinematic: it makes skin angry. Fragrance is the most common cause of allergic contact dermatitis from cosmetics in patch-test data, and the American Contact Dermatitis Society named fragrance its Allergen of the Year in 2007. When an entire medical specialty gives a chemical category an award, take the hint.

A moisturizer is the worst possible vehicle for an allergen. You apply it every day, over large stretches of skin, often skin that's already cracked or eczema-prone, and then you leave it on. That's a textbook setup for developing a sensitivity. And fragrance allergy, once acquired, tends to be permanent, at which point half the personal care aisle becomes hostile territory.

"Unscented" is a decoy word

Now the trap within the trap: "unscented" and "fragrance-free" sound like synonyms and are not. Neither term is legally defined for cosmetics, but the working definitions, spelled out in the EPA's Safer Choice program among other places, split cleanly. Fragrance-free means no fragrance materials went in. Unscented means the product doesn't smell like much, which manufacturers often achieve by adding a masking fragrance to cancel out the odor of the base ingredients.

So an "unscented" lotion can contain the exact chemicals a fragrance-sensitive person is trying to avoid. Also filed under decoy: "scented only with essential oils." Essential oils are fragrance. Lavender oil and orange oil are complex chemical mixtures that include some of the most common contact allergens dermatologists patch-test for.

The fix takes ten seconds. Ignore the front of the bottle and scan the ingredient list for "fragrance" or "parfum." If either shows up, it isn't fragrance-free, whatever the marketing wants you to feel.

What EWG gets right here, and what it overstates

Search any lotion online and you'll land on EWG's Skin Deep database, which scores fragrance harshly. On the core complaint, EWG has a point: an undisclosed mixture can't be independently evaluated by anyone, and "trust us" is not a safety dossier.

But a hazard score built on missing data measures uncertainty, not demonstrated harm, and a Skin Deep number can read like a verdict when it's closer to a shrug. If you've used a scented lotion for years with calm skin, nothing in the published science says it has been quietly hurting you. "Contains chemicals we can't see" is a genuine accountability problem. It is not the same claim as "dangerous," and blurring the two is how fear-marketing gets a foot in your door.

The boring winners, plus one for the crunchy shelf

The pleasant surprise: this problem is already solved, cheaply, by brands with no story to sell. That's exactly why they get top billing here.

Vanicream built its entire line around leaving things out: no fragrance, no dyes, no botanical extracts, none of the common preservative allergens. Its moisturizing cream has been a dermatologist default for years. The honest knock is that it looks and feels like a medical supply, because it more or less is one.

CeraVe's core moisturizers are fragrance-free, ceramide-heavy, and sold everywhere for drugstore money. The lineup has sprawled into dozens of products, though, so read the label on the specific tube in your hand rather than trusting the brand name.

If you want plants in the mix anyway, Mambino Organics, a small Los Angeles brand focused on pregnancy and baby skincare, formulates with certified organic ingredients and lists them plainly. One honest caveat: a number of its products are scented with essential oils, and your immune system does not care that the limonene came from an orange. It's a values pick, not an allergy pick.

The same ten-second label scan works on shampoo, deodorant, laundry detergent, and everything else that touches skin. One rule, every aisle. There aren't many of those in this business.
