Ätherische Öle vs. Duftöle: Was ist der Unterschied?
Ätherische Öle vs. Duftöle: Was ist der
Walk into any health shop or search online for essential oils and you will see the word „pure“ everywhere. Pure lavender oil. Pure peppermint oil. 100% pure essential oils.
But what does „pure“ actually mean when it comes to essential oils — and how can you tell when a product is genuinely pure versus something quite different wearing the label?
This guide cuts through the confusion. You will learn exactly what makes an essential oil pure, why purity directly determines whether aromatherapy actually works, and how to identify and buy oils you can trust.
—
A pure essential oil is a concentrated plant extract that contains only the volatile aromatic compounds recovered from a single botanical source — without synthetic additives, dilutions, or chemical alterations.
That sounds simple, but the reality of the essential oil industry makes it complicated. A bottle labelled „pure lavender oil“ might contain:
All four of those additions are common. None of them are „pure.“
True pure essential oil means:
—
The method used to extract essential oils from plants has a direct effect on purity and quality.
The most common method. Steam passes through plant material, carrying volatile compounds with it. The resulting condensate separates into essential oil and hydrosol (plant water).
Used for: Lavender, eucalyptus, peppermint, most herbs and woody plants.
Mechanical extraction without heat. The peel or rind is literally pressed to release oils.
Used for: Citrus oils — orange, lemon, grapefruit, bergamot.
Uses a chemical solvent (typically hexane or ethanol) to dissolve the aromatic compounds from delicate plant material that heat would damage.
Used for: Jasmine, rose, neroli. The resulting product is called a „concrete“ or „absolute“ — not technically a pure essential oil, but still a concentrated botanical extract.
What to watch: Some mass-market products use solvent extraction but label the result as a „pure essential oil.“ If you want purely steam-distilled or cold-pressed products, check the label carefully.

This is where buyers most commonly get misled.
| Property | Pure Essential Oil | Fragrance Oil |
|---|---|---|
| Source | Single botanical plant | Synthetic lab-created compounds |
| Aroma complexity | Multiple compounds, evolves as it diffuses | Consistent, flat scent profile |
| Therapeutic use | Used in aromatherapy for physiological effects | Designed only for scent |
| Price | £10–£200+ depending on plant | £3–£20 |
| Regulatory definition | No legal standard in the UK/EU | Must list ingredients |
| Allergen risk | Natural allergens present | Synthetic allergens may be undisclosed |
Using an impure essential oil is not just a waste of money — it can cause real problems.
Synthetic fragrance compounds are among the most common causes of contact dermatitis. When diluted in a „pure“ essential oil at high concentration, they can cause serious skin irritation, particularly in people with sensitivities.
EU cosmetic regulations (including UK post-Brexit) require disclosure of 26 specific fragrance allergens on product labels. Many mass-market „pure“ oils do not comply with this — either because they use non-disclosed synthetic versions of these allergens, or because they are simply mislabelled.
The case for using essential oils in aromatherapy rests entirely on their chemical composition. A synthetic fragrance oil may smell identical but lacks the full spectrum of natural compounds that interact with the olfactory system and the body. You are diffusing perfume, not therapy.
Some adulterated essential oils — particularly patchouli, cedarwood, and tea tree — have been found to contain synthetic compounds that act as endocrine disruptors. This is documented in peer-reviewed toxicology literature.
—
You cannot fully verify purity without a laboratory gas chromatography-mass spectrometry (GC-MS) test, but there are several home checks that will flag obvious problems.
Place one drop of essential oil on a white paper towel. Pure essential oils evaporate completely within 1–2 hours with no oily residue. If there is a persistent greasy stain, the oil has been diluted with a carrier oil.
Note: Citrus oils will leave a slight residue because they contain non-volatile waxes — this is normal.
Look for:
If a 10ml bottle of Rose damascena (rose Otto) costs less than £30, it is not pure rose essential oil. It takes approximately 60 roses to produce one 10ml bottle of genuine rose Otto. The maths do not work for a £6 price tag.
Pure essential oils smell complex — the scent profile changes from the moment you open the bottle to a few minutes after application. Synthetics smell exactly the same from first sniff to last. This takes experience, but your nose learns quickly.

Given the regulatory gaps in the essential oil industry, here is what to look for when purchasing:
Look for:
Brands that publish third-party GC-MS test results for every batch — including Aroma Sentia’s own ecological essential oil range — are demonstrating transparency that adulterated products cannot fake.
Extremely low prices almost always indicate dilution, synthetic blending, or mislabelling. A trustworthy pure essential oil costs what the raw botanical material costs — and some plants are simply expensive to produce in pure form.
If a supplier cannot tell you the botanical name, country of origin, and extraction method of their oils, that is a warning sign. Legitimate suppliers maintain this information as standard practice.

Understanding how oils are commonly adulterated helps you recognise the warning signs:
—
You will see bottles labelled „therapeutic grade essential oils“ — this has no official legal or scientific definition in the UK or EU. It was coined by doTERRA in 2008 as a marketing phrase, not a quality standard.
What actually matters:
—
Even a genuinely pure essential oil will degrade if stored improperly. Essential oils are volatile — they evaporate and oxidise when exposed to heat, light, and oxygen.
Storage best practices:
—
The word „pure“ on an essential oil label means very little without context. What matters is:
At Aroma Sentia, every essential oil is sourced from traceable ecological farms and supplied with full botanical transparency — because purity is not a marketing claim, it is the baseline standard for anything we sell.
