Are essential oils fragrance-free?

The short answer

We work from documents and have not tested any products. We looked for a regulator, allergy society or dermatology society that says essential oils count as fragrance, and we found no such statement. What we did find is a set of statements that point the same way without saying it outright. The rest of this page lays them out, then states the rule this site applies.

What DermNet says

DermNet’s page on allergic contact dermatitis to essential oils, retrieved 2026-11-14, describes essential oils as “volatile aromatic substances obtained from plant material” and says they have been widely used in aromatherapy, balneotherapy and perfumery. It says they are also increasingly used in household products and aerosol diffusers, and that allergic contact dermatitis can develop as a delayed hypersensitivity reaction when essential oils contact the skin. It reports cases of airborne contact dermatitis caused by fragrance diffusers.

Its page on fragrances and perfumes says a perfume “is formed from fragrant essential oils derived from plants and spices or synthetic aromatic compounds.” That puts essential oils inside perfumery. It is a description of how perfume is made, not a labelling rule.

The fragrance allergy page says fragrances “can either be made from a natural extract or synthesised.” It also says a 2011 review by the European Scientific Committee on Consumer Safety listed 82 substances established as contact allergens, 54 synthetic chemicals and 28 natural extracts. And it says products labelled “fragrance-free” could still include masking fragrances, and that a product may contain an unidentified fragrance if it lists “botanical”, “herbal” or “natural” ingredients.

What the FDA excerpts say

The FDA’s Fragrances in Cosmetics page, retrieved 2026-11-11, states: “There is no regulatory definition for ‘essential oils,’ although people commonly use the term to refer to certain oils extracted from plants. The law treats Ingredients from plants the same as those from any other source.”

The same page says fragrance and flavor ingredients can be listed simply as “Fragrance” or “Flavor” on a cosmetic label. It describes fragrance formulas as “complex mixtures of many different natural and synthetic chemical ingredients.” It also says even some products labeled “unscented” may contain fragrance ingredients. Our fragrance-free vs unscented guide covers that wording.

None of these excerpts says an essential oil must be declared as “Fragrance”. They also do not say it may be declared separately. We make no claim either way.

One example: lavender oil

A 2016 study in Acta Dermato-Venereologica, which we classify as observational, describes lavender oil as an essential oil whose main components, linalool and linalyl acetate, autoxidize in air and form sensitizing hydroperoxides. Among patients already being patch-tested for suspected allergic contact dermatitis, 2.8% reacted to oxidized lavender oil, and 52% of those reacted to the fragrance markers of the baseline series. The authors say oxidized lavender oil showed among the highest frequencies of contact allergy of the essential oils studied.

That population was patients under investigation, so it does not give a rate for the general public. It does show a dermatology paper treating a common essential oil as relevant to fragrance allergy.

This site’s rule

Everything above is background. The test we apply is ours:

On this site, a product whose ingredient list includes essential oils is not called “fragrance-free.”

This is an editorial rule, not a regulation and not a statement from the FDA or any society. We use it because the lens of this site is the absence of added scent ingredients, and the DermNet material above ties essential oils to perfumery and to fragrance-type allergy. Our guide to fragrance-free products and the fragrance-free perfume page apply the same test. For help reading a list, see how to read an ingredient list.

On the label

The EU’s glossary of common ingredient names (Commission Decision (EU) 2019/701, text retrieved 2026-11-14) lists names that can appear on a cosmetic ingredient list. We looked up the substances this page mentions and found an exact entry for each:

Substance	Glossary name	Entry number
Lavender oil	LAVANDULA ANGUSTIFOLIA OIL	13204
Tea tree oil	MELALEUCA ALTERNIFOLIA LEAF OIL	14026
Linalool	LINALOOL	13416
Linalyl acetate	LINALYL ACETATE	13420

There was no name in this lookup without an exact entry. A glossary entry only tells you what a name is called in the glossary. It does not say whether the substance counts as fragrance, and we make no such claim.

Fragrance is not inherently harmful

Fragrance is not harmful in itself, and this page does not argue that it is. The practical issue is information. People who have been told to avoid fragrance, or who react to certain products, need a label they can read. Essential oils are one of the places where wording such as “natural” or “botanical” can leave the reader unsure. Browse the essential oils concern hub for related pages, or the ingredients and materials category.
