Fragrance-Free vs. Unscented, and Why the Difference Matters

What each label is actually claiming

“Fragrance-free” is a claim about an ingredient: nothing was added purely to make the product smell like something. According to the American Academy of Dermatology, “unscented” is a claim about a sensory result instead — the product has no noticeable smell, which manufacturers commonly achieve with a masking fragrance added specifically to neutralize the odor of other ingredients in the formula, not by omitting fragrance chemicals. Both labels can land you with a scent-free product. Only one of them tells you whether a fragrance ingredient is actually in the bottle.

Why the distinction matters if you react to fragrance

Fragrance is one of the most common triggers of contact dermatitis from personal care and cleaning products, and a masking fragrance is still a fragrance chemical, whether or not you can smell it. The AAD’s own guidance for eczema-prone skin is specific on this point: choose products labeled fragrance-free, because an unscented product can still contain the fragrance ingredients that trigger a flare — the masking scent just cancels out the smell of them, not the exposure. If you’re shopping around a fragrance sensitivity, “fragrance-free” is the label that’s actually answering your question; “unscented” is answering a different one.

Neither claim is independently verified — but you can check the ingredients yourself

No U.S. agency certifies a “fragrance-free” or “unscented” claim on cleaning product packaging. They’re both self-declared by the manufacturer. What you can check independently is the ingredient list itself: California’s Cleaning Product Right to Know Act requires manufacturers of designated cleaning products sold in the state to disclose any fragrance allergen present at or above 0.01% concentration (100 parts per million), counting contributions from every ingredient in the product, including essential oils. That disclosure has applied to manufacturer websites since January 2020 and to the product label itself since January 2021 — though the label can take a shortcut, printing only “Contains fragrance allergen(s)” and pointing to the website for the specific list. If a product claims “unscented,” that online ingredient disclosure is where you’d actually find out whether a masking fragrance, and which one, is in it.

How to shop around a fragrance sensitivity

Treat “fragrance-free” as the claim that matters and “unscented” as marketing about smell, not formulation. If a product is fragrance-free, that’s stated plainly, not implied by the absence of a scent. When in doubt, the manufacturer’s own online ingredient disclosure — required for designated cleaning products sold in California, and commonly published nationwide since it’s cheaper to maintain one ingredient list than several — settles it either way.
