Essential oils are fragrance too: the natural scent loophole

Read the front of a "naturally scented" body wash and you will not find the word fragrance anywhere. Read the back and you may find Lavandula Angustifolia Oil, Citrus Limon Peel Oil and, further down, Limonene and Linalool. That product is fragranced. It just did not use the word.

What an essential oil is

An essential oil is the concentrated aromatic part of a plant: the oil steamed out of lavender flowers, pressed from lemon peel, distilled from tea tree leaves. It is used in cosmetics for one reason, its smell, and occasionally for a second, a mild antimicrobial effect. Chemically it is a mix of the same molecules a perfumer uses: limonene, linalool, geraniol, citral, eugenol.

Why it counts as fragrance

Those molecules are the ones EU rules make brands declare by name because a meaningful share of people react to them. The rule does not care whether the limonene came from a lab or a lemon. If you are patch testing or you know your skin dislikes perfume, an essential oil is the same question in a different bottle.

That is why the fragrance-free check treats lavender, citrus peel, mint, rosemary, eucalyptus, tea tree, ylang-ylang, geranium, rose, sandalwood and the rest of the aromatic plants as fragrance when they appear as an oil or absolute.

What does not count

Carrier oils. Simmondsia Chinensis Seed Oil (jojoba), Helianthus Annuus Seed Oil (sunflower), Argania Spinosa Kernel Oil (argan), Prunus Amygdalus Dulcis Oil (sweet almond), Cocos Nucifera Oil (coconut) are fats, not scents. They are usually listed as seed, kernel or fruit oils, and they leave the fragrance-free answer untouched. So do plant extracts and floral waters, which carry far less of the aromatic fraction.

The names to watch

Look for an oil, absolute or resin from these plants: Lavandula, Citrus (limon, aurantium, bergamia, paradisi), Mentha, Rosmarinus, Eucalyptus, Melaleuca, Cananga (ylang-ylang), Pelargonium (geranium), Rosa damascena, Santalum, Cymbopogon (lemongrass), Cinnamomum, Eugenia (clove), Salvia, Thymus, Origanum, Pinus, Juniperus, Boswellia (frankincense), Pogostemon (patchouli), Vetiveria.

The short version

Fragrance-free is about whether scent was added, not about whether the scent came from a plant. If a product lists an essential oil, it is scented, and the declared allergens below it are the proof.
