Masking fragrance
This concern covers the gap between "unscented" and fragrance-free. A product can carry the word on its front label and still list a fragrance ingredient meant to cover other smells.
Start with [fragrance-free vs unscented](/guide/fragrance-free-vs-unscented/). It reports that the FDA says even some products labeled "unscented" may contain fragrance ingredients, added to mask the smell of other ingredients, so the ingredient list is better evidence than either front-of-pack word.
[How to read an ingredient list for fragrance, parfum and aroma](/guide/how-to-read-an-ingredient-list-parfum-aroma/) says to scan every position on the list. [Fragrance allergen names on ingredient labels](/guide/fragrance-allergen-names-on-ingredient-labels/) covers seven chemical names that can appear.
Two product pages show the point in practice. [Fragrance-free laundry detergent](/fragrance-free-laundry-detergent/) reads each maker list. [Unscented trash bags](/unscented-trash-bags/) reports that bags publish no list, so only a maker statement of "unscented" exists. [Fragrance-free perfume](/guide/fragrance-free-perfume/) reports that the phrase does not fit DermNet's description of a perfume.
What the evidence says
The pages rest on FDA and EPA statements, DermNet, and maker ingredient lists read on the dates shown. No page here tests how much masking fragrance a given product contains.

What we don't fully know
- Products without published ingredient lists, such as trash bags, cannot be checked beyond a maker statement.
- A list entry of fragrance or parfum does not reveal which chemicals are inside.
Product guides
- Best fragrance-free laundry detergent
Six detergents pass our fragrance-free check on the maker's own ingredient list, retrieved 2026-11-11 and 2026-11-12: All Free Clear, Arm & Hammer Sensitive Skin Free & Clear, ECOS Free & Clear, Seventh Generation Free & Clear, Tide Free & Gentle and Charlie's Soap powder. A product marketed as unscented or free and clear is not the same thing, so check the list for fragrance, parfum or aroma. Several well-known brands could not be verified and are not recommended or rejected here. - Best unscented trash bags
Two bags have a confirmed maker statement of "unscented", Seventh Generation Extra Strong Tall Kitchen and Glad ForceFlex Quick-Tie. Bags publish no ingredient list, so that statement is all there is, and it does not make them fragrance-free.
Guides and explainers
- Fragrance allergen names on ingredient labels
This guide covers citronellol, geraniol, coumarin, eugenol, benzyl salicylate, hexyl cinnamal and benzyl alcohol. For each we give what PubChem and PubMed abstracts say, and where a source is missing we say so. We found no source for how any of them is spelled on a label. - Fragrance-free perfume
DermNet describes a perfume as a liquid mixture used to emit a pleasant odour, so the phrase "fragrance-free perfume" does not fit that description. We found no source defining it, so read the ingredient list and treat the name as the maker's wording. - Fragrance-free vs unscented, and what masking fragrance is
They are not the same thing on a label. The FDA says even some products labeled "unscented" may contain fragrance ingredients, added to mask the smell of other ingredients, so the ingredient list is the better evidence than either front-of-pack word. - How to read an ingredient list for fragrance, parfum and aroma
Read the full list, not just the top. US labels may say "fragrance"; EU labels use "parfum" or "aroma". Scan every position for Fragrance, Parfum, Aroma, Perfume or essential oils, because order and the 1 percent rules do not make position a safe guide. - "Unscented" and "sensitive" don't mean fragrance-free: what the ingredient lists show
A word on a product name or maker page is not the ingredient list. On six maker pages we re-read on 14 November 2026, three products use "unscented" wording and four carry "sensitive" in the name or description (one has both), and every one lists "Fragrance" or "Fragrance (Parfum)" among its ingredients. The FDA says even some products labeled "unscented" may contain fragrance ingredients.
