Natural fragrance ingredients come from plants, such as flowers, herbs, spices, wood, and fruits. Synthetic fragrance ingredients are made by humans in a laboratory. According to Waarzitwatin from the Dutch government, synthetic fragrance ingredients usually smell stronger and remain noticeable longer because they are purer. So natural is not automatically better, and synthetic is not automatically worse. Almost every modern perfume contains both. Below, you will read how both types are created, how they smell and how long they last, what they mean for your skin and the environment, and what to look for when choosing a fragrance.
Briefly summarized
- Origin: natural fragrance ingredients are extracted from plants, while synthetic ones are built by chemists. Many perfumes combine both.
- Scent and strength: synthetic fragrance ingredients are often purer, smell the same every time, and last longer. Natural raw materials vary from harvest to harvest.
- Safety: natural does not automatically mean safer. Plant extracts can also contain allergens. How safe a fragrance is depends on the substance, the concentration, and the product.
- Environment: the impact varies by ingredient and production process. A natural label does not say everything about sustainability.
- Price: natural raw materials are often expensive because of manual labor, limited cultivation land, and changing weather. Synthetic ones are uniform and readily available.

What do natural and synthetic mean in perfume?
In a perfume, the fragrance ingredients determine how it smells. The rest of the bottle is mainly a carrier, such as alcohol and sometimes some water. Those fragrance ingredients can be divided into two groups.
Natural fragrance ingredients come directly from nature. Waarzitwatin lists herbs, spices, flowers, and fruits as examples. Think of bergamot oil from the peel of a citrus fruit, lavender oil from the flowering plant, or resin and wood for warm, deep notes.
Synthetic fragrance ingredients are human-made chemical substances. That may sound artificial, but a synthetic fragrance ingredient can be exactly the same molecule as the one found in a flower. Chemists call that a nature-identical substance. There are also aroma molecules that do not occur in nature and make new scents possible.
In practice, a perfumer rarely chooses one or the other. The international industry association IFRA explains that natural and synthetic ingredients are used side by side: synthetic materials supplement natural ones, imitate rare fragrance notes, and require fewer raw materials. The technical brochure from raw material producer H&R also describes modern compositions as mixtures of essential oils, absolutes, and aroma chemicals. This is how the perfumer achieves the desired quality while keeping the perfume within the agreed price.
So the question is usually not whether a perfume contains synthetic substances, but in what proportion, and what those substances do for the scent.
How natural fragrance ingredients are extracted
Flowers, wood, resins, spices, and citrus peels are harvested and, according to IFRA, often processed close to the harvest site into essential oil or a so-called concrete. There are three main methods.
Steam distillation
The best-known method. Steam passes through the plant material and releases the volatile aromatic compounds from the plant cells. After cooling, water and oil separate naturally, and the oil is drained off. This is described in the H&R raw materials brochure. Lavender, patchouli, and many woods are processed this way.
Pressing
Citrus oils, such as those from lemon, orange, and bergamot, are usually obtained by pressing the peel. No heat is involved, which helps preserve the fresh, sparkling scent.
Extraction into an absolute
Delicate flowers such as jasmine cannot tolerate steam. That is why the fragrance compounds are first extracted with a solvent. The result is a waxy mass, the concrete. It is then washed with alcohol to remove waxes and colorants. What remains is the concentrated absolute.
Each method yields a different fragrance profile, even from the same flower. A review by the American Chemical Society shows that headspace techniques and steam distillation produce concentrates that differ in amount, and often also in type, from one another. A distilled rose therefore smells different from the rose in your garden.
How synthetic fragrance ingredients are created
Synthetic fragrance ingredients often begin with nature. Chemists first break down a natural scent using analytical techniques such as gas chromatography. This helps them identify the molecules that define the character of the fragrance. According to NEA Netherlands, those molecules can then be recreated from other raw materials that are more readily available.
Production is changing too. IFRA reports that chemists are increasingly making synthetic fragrance ingredients through green chemistry or biotechnology, for example using enzymes or fermentation. So synthetic does not automatically mean petrochemical. The raw material may also be plant-based.
What makes synthetic substances so valuable to a perfumer:
- Consistency: every batch smells the same, regardless of weather or harvest.
- Availability: rare or vulnerable plants do not need to be harvested in large quantities.
- New scents: some notes, such as fresh aquatic or “clean” tones, exist only thanks to synthetic molecules.
- Fragrance notes that nature does not provide: some flowers, such as lily of the valley, do not yield usable oil. A synthetic molecule still brings that scent into the bottle.
Do they smell different? Scent, strength, and lasting power on the skin
For most people, this is where the difference is really noticeable.
Strength and duration. According to Waarzitwatin, synthetic fragrance ingredients are often purer and more consistent, and can smell stronger than natural substances. As a result, you notice them for longer. Many natural oils, especially citrus, are very volatile. They give a beautiful opening but have disappeared after a short time.

Character. Natural raw materials often have a complex, somewhat rougher scent, with hundreds of different molecules in one oil. Fans appreciate that complexity. The downside is that the character can vary with climate, soil, harvest, and season. Synthetic substances are tighter and more predictable. In a well-constructed perfume, the two reinforce each other: the natural materials add depth, the synthetic ones add strength and stability.
Storage life in the bottle. Natural oils are more sensitive to light, heat, and oxygen. How to store a bottle properly is explained in our article about perfume shelf life.

Is natural safer for your skin?
No, not automatically. This is the biggest misconception about this topic. A plant does not make fragrance compounds for our skin, and many essential oils contain substances that can irritate or cause an allergy. The same applies to synthetic substances: some are very mild, while others require caution. How safe a fragrance is depends on the properties of the substance, the concentration, the full formula, and how you use the product.
In the Netherlands, perfumes fall under the European Cosmetics Regulation. According to the NVWA, strict safety requirements apply. The NVWA oversees the safety of cosmetics and investigates reports of allergic reactions or unsafe products. Those rules apply to natural and synthetic ingredients in the same way.
What does that mean for you?
- Read the ingredients list. Substances known as allergens are often listed separately. We explain what those names mean in allergens in perfume.
- Test a small area first. Apply a little to the inside of your wrist or elbow and wait a day before spraying the fragrance on your neck.
- Do you get itching, redness, or bumps? Then stop using the product. If it persists or returns, see your doctor. They can refer you to a dermatologist for an allergy test so you know which substance to avoid.
- Sensitive skin? Spray on your clothes instead of your skin, and read our tips for perfume for sensitive skin.

Environment and animal welfare: what is more sustainable?
Many people think natural also means greener. It is not that simple. A natural oil can require a lot of farmland, water, and transport. A synthetic substance, on the other hand, can be made efficiently, or it may require a lot of energy and chemicals. Researchers therefore look at the entire life cycle of a fragrance ingredient, from raw material to waste. A study in Green Chemistry (2023) uses such a life cycle analysis and shows that environmental impact differs greatly by production process and raw material.
Biodegradability is not confined to one side either. An analysis in Chemistry: A European Journal (2024) estimates that about 54% of a perfumer’s palette is biodegradable. Of that, three-fifths is natural and two-fifths synthetic. The researchers say that a perfume that is 100% renewable and biodegradable remains a major challenge for chemistry.
For animal welfare, there are two questions: are there ingredients of animal origin, and was the product or its ingredients tested on animals? A vegan perfume contains no animal ingredients. Whether a brand truly works without animal testing can be identified with the tips in cruelty-free perfume.
Sustainability is not only about the fragrance ingredients either. Packaging and the amount of perfume you need also matter. A scent that lasts longer means you spray it less often. Our article on sustainable perfume goes deeper into that, and anyone who wants to know what else is in a bottle should also read microplastic-free perfume.
Why natural perfume is often more expensive
The price of a natural raw material has little to do with the scent itself and much to do with the way it is extracted. The H&R brochure gives three reasons:
- Manual labor. Many flowers and plants are harvested and processed by hand.
- Changing weather. A bad season can cause the quality of a harvest to fluctuate from year to year.
- Limited cultivation land. There is only so much land on which a plant grows well, so the quantity is limited.
According to the same source, nature-identical aroma chemicals are often cheap, uniform, and can be produced in unlimited quantities. That explains why a perfume with many rare natural absolutes can be so expensive.
Still, the raw material accounts for only part of the retail price of a designer perfume. A large share goes to advertising, famous faces in campaigns, luxury boxes, and heavy bottles. That is where you, the buyer, have the real opportunity to save money without compromising on scent.
How to choose a fragrance that suits you
Instead of choosing between natural and synthetic, it is better to focus on what you really want from a perfume.
- How long do you want to smell it? If you want a fragrance that lasts from morning to evening, choose a higher concentration of perfume oil and notes with a strong base, such as wood, amber, or musk.
- Which fragrance family appeals to you? Fresh and citrusy, floral, woody, or oriental. If you know a designer fragrance you like, you already know which direction you want to go.
- How does your skin react? Check the allergens on the label and test a small area first.
- What matters to you for animals and the environment? Look for vegan ingredients, no animal testing, and packaging without unnecessary luxury.
- What are you actually paying for? Ask yourself what part of the price goes to the scent and what part goes to marketing and packaging.
- Where is the alcohol? The carrier affects how the scent opens. You can read more about that in alcohol in perfume.

Our view on natural and synthetic
When we talk to customers about fragrance, we often hear the same question: isn’t natural simply better? We understand that question. The word natural sounds soft, honest, and healthy. But anyone who knows perfumery from the inside knows that a beautiful scent is not a choice between nature and the lab. It is craftsmanship with both.
What matters to us is what you experience on your skin: a fragrance you recognize, that you love, and that you can smell all day. That is why we focus on a high concentration of perfume oil. That way, you get a scent that lasts, even if you only spray a few times in the morning.
We also care about where your money goes. With many well-known brands, you pay for a campaign, a box, and a name. We skip those costs so you get a fragrance with the same experience as the expensive brands, without the high price tag.
And we deliberately choose vegan fragrances that are cruelty-free. We do not see that as an extra, but as a basic requirement. Thousands of positive reviews show us that many people feel the same way.

Frequently asked questions
Is a synthetic fragrance bad for you?
Not automatically. In the Netherlands, synthetic fragrance ingredients fall under the same strict European cosmetic rules as natural ones. Whether a substance irritates your skin depends on the substance, the concentration, and your own sensitivity. If your skin reacts to a perfume repeatedly, have your doctor or dermatologist find out which substance is responsible.
Why does a synthetic fragrance last longer?
Synthetic fragrance ingredients are often purer and therefore smell stronger, which means you notice them for longer. Many natural oils, such as citrus, are volatile and disappear quickly. The concentration of perfume oil and the base notes also determine how long a fragrance lasts.
Does a perfume that is completely natural exist?
Yes, they exist, but they are a small group. They often smell softer, can vary by batch, and usually last for a shorter time. The vast majority of perfumes, including those from well-known designer brands, combine natural and synthetic substances.
Is a vegan perfume the same as a natural perfume?
No. Vegan means that it contains no ingredients of animal origin. A vegan perfume can contain natural and synthetic fragrance ingredients. A natural perfume is not always vegan, because beeswax or animal-derived raw materials are also natural.
Can you smell the difference between natural and synthetic?
With a trained nose, sometimes yes: natural oils have a more complex, slightly rougher character, while synthetic substances have a tighter profile. In a well-made perfume, they are blended so that you mainly smell the whole. That is why it is better to choose based on fragrance family and longevity than on origin.
