Fragrance-free vs unscented: what the label really means

What the FDA says

The FDA has no regulations governing the words “unscented” or “fragrance-free”, but cosmetic labelling must be truthful and not misleading. In its explanation, an unscented product has no noticeable scent but may contain “masking” fragrance ingredients to cover the smell of other ingredients. Because “fragrance” refers to a specific kind of ingredient, a product labelled fragrance-free should not contain any added fragrance ingredients. It can still smell of something, pleasant or not, from its other ingredients.

On a US label a perfume can be listed simply as “Fragrance” (or “Flavor”), without its components, because the law that requires ingredient lists cannot be used to force a company to reveal trade secrets. The Modernization of Cosmetics Regulation Act of 2022 requires the FDA to make a rule on naming fragrance allergens, but as of 3 November 2026 no proposed or final rule has been published. “Hypoallergenic” has no federal standard either: the FDA says the term means whatever a particular company wants it to mean.

How to read an EU or UK label

EU and GB ingredient lists use INCI names. Article 19 of the Cosmetics Regulation says perfume and aromatic compositions, and their raw materials, are listed as “Parfum” or, for flavours, “Aroma”. A masking fragrance is still a perfume composition, so it shows up as Parfum too. What the EU adds is the second step: the labelled fragrance allergens above 0.001% (leave-on) or 0.01% (rinse-off) must be named after it. Since 1 August 2026, products newly placed on the EU market name up to 81 entries, including essential oils such as lavender, lemon peel and clove oil; Great Britain still uses the original list. Our fragrance allergen checker lists them all.

Plant oils are the grey area. A brand may list “Lavandula Angustifolia Oil” or “Citrus Limon Peel Oil” as a skin-conditioning ingredient rather than as Parfum, but the oil carries the same allergens whatever it is there for. The decoder flags those oils and the labelled allergens separately from the perfume, so you can decide for yourself.

Worked examples

“Unscented” face cream with “Parfum (Masking Fragrance)”. This is the default above. It matches the FDA's description of unscented: there is a fragrance, added to cover a smell. Not a choice for someone avoiding fragrance.

“Fragrance-free” lotion listing Lavandula Angustifolia Oil and Linalool. No Parfum, but a scented oil that is itself on the EU allergen list, plus linalool, one of the original 26. The decoder marks this for checking: it is not the same as no fragrance.

“Fragrance-free” cleanser with Benzyl Alcohol and nothing else scented. Benzyl alcohol is often a preservative, and Annex III only covers it when it is used for other purposes. The decoder notes it but finds the claim consistent.

Common mistakes

• Treating unscented as fragrance-free. They are different promises.
• Trusting “natural fragrance”. Essential oils are fragrance, and many contain the same allergens as synthetic perfume.
• Reading the front, not the back. The ingredient list is the part the law controls most closely.
• Using your nose as the test. A masking fragrance is designed to smell of nothing.
• Relying on “hypoallergenic”. In the US it has no federal standard or definition.

Labels you can't trust: counterfeit perfume

A label only helps if the product is genuine. On 2 November 2026 the UK Intellectual Property Office launched its “Face the Fakes” campaign after tests of seized counterfeit beauty products: one counterfeit fragrance contained around 80% methanol, a toxic alcohol, and nicotine was found in a counterfeit perfume. The IPO notes that a discount doesn't mean something is fake, but an unusually low price can be a warning sign, and that nearly three in four people who bought counterfeit cosmetics and toiletries bought them online. US Customs and Border Protection likewise warns that counterfeit perfume and makeup can be made with substandard materials that are hazardous to health.
