Unscented means a product is made to have no noticeable smell — but it may still contain fragrance ingredients, added in small amounts to mask the odour of its other ingredients. Fragrance-free usually means that no fragrance ingredients have been added at all, though the product may still smell faintly of its other ingredients. Neither term has a strict legal definition in the United States, and usage varies between brands and countries. If you are avoiding fragrance, the reliable guide is the ingredient list, not the front of the pack.
Why "unscented" can contain fragrance
Many cosmetic ingredients — oils, waxes, emulsifiers, some active ingredients — have a smell of their own, often fatty, chemical or medicinal. To make a product smell of nothing, a manufacturer may add a little fragrance, just enough to neutralise or cover those odours without giving a recognisable scent. The result is unscented to the nose, but not free of fragrance.
The US Food and Drug Administration notes on its page about fragrances in cosmetics that even some products labelled "unscented" may contain fragrance ingredients, and suggests that people concerned about fragrance sensitivities choose fragrance-free products and check the ingredient list carefully.
What "fragrance-free" usually means
Fragrance-free is usually taken to mean no fragrance ingredients were added — neither to give a scent nor to mask one. But:
- It may still smell. The base ingredients can have a faint natural odour.
- It is not always defined. In the United States, the FDA does not have regulations that define either term, though labelling must not be misleading. Other regulators treat the words differently; Health Canada’s guidance, for example, describes "fragrance-free" or "unscented" as meaning no fragrance was added, or only a masking agent.
- Some ingredients have a scent but another purpose. A plant extract or essential oil added for another stated purpose may still smell. Read the list.
The front of the bottle makes a promise; the back tells you how it was kept.
How to check the ingredient list
On cosmetics, fragrance usually appears as one word:
- "Parfum" — the name used in the European Union and many other markets, under the international naming system for cosmetic ingredients.
- "Fragrance" — the name used in the United States. FDA rules allow fragrance and flavour ingredients to be listed simply as "fragrance" or "flavor", because their formulas can be trade secrets.
Look also for named fragrance substances — linalool, limonene, citral, geraniol and others — that EU rules require to be listed above certain amounts because they can cause allergies in sensitive people. A product listing these, or essential oils, is not fragrance-free in practice. Our full guide to the label is How to Read the Ingredient List on a Perfume.
"Masking fragrance" and "masking agent"
Some products list a "masking fragrance" or "masking agent". These are present to cover an odour, not to give a scent. They are a common reason an "unscented" product still contains fragrance materials.
Unscented, fragrance-free and "clean"
None of these is the same as "clean" — a word used both for a style of perfume and for a marketing claim about ingredients. A perfume can smell "clean" while containing a great deal of fragrance; see What Does "Clean" Mean in Perfume?. And "natural" does not mean free of fragrance substances or allergens; see Is Natural Perfume Better Than Synthetic?.
Why it matters for people who wear perfume
If you wear perfume, unscented and fragrance-free products help in two ways:
- No clashes. A scented lotion, deodorant or hair product can compete with your perfume. Unscented ones let your fragrance be the only scent. See Perfume vs Deodorant and How to Layer Perfume.
- Better longevity. Unscented moisturiser under perfume is one of the simplest ways to make a fragrance last. See How to Make Perfume Last Longer.
Anyone with a diagnosed fragrance allergy or a skin condition should follow a doctor’s or dermatologist’s advice about which products to use.
Common questions
Is unscented the same as fragrance-free?
No. Unscented products may contain a small amount of fragrance to mask other odours; fragrance-free products usually contain none added.
Can a fragrance-free product have a smell?
Yes. Its other ingredients can smell faintly, even with no fragrance added.
What does "parfum" mean on an ingredient list?
It is the name for the fragrance mixture in a product, used in the EU and many other markets. In the US the word "fragrance" is used.
Which should I choose if I am sensitive to fragrance?
Fragrance-free products, with the ingredient list checked — and the advice of a doctor if you have a diagnosed allergy.
