Perfume Raw Materials: A Complete Perfumer’s Guide
Creating a perfume does not simply mean mixing essential oils. The contemporary perfumer’s palette includes natural raw materials, aroma chemicals, fragrance bases, accords, absolutes, resinoids, musks, woody and amber molecules, solvents, and technical materials.
Some ingredients come from natural matter; others are obtained through synthesis or biotechnology; still others are professional blends already constructed to create a particular note or function. The most useful distinction, however, is not simply between “natural” and “synthetic.”
When a perfumer chooses a raw material, the main question is: what will this material do in the formula? Will it provide diffusion, volume, persistence, or a recognizable olfactory signature? Will it make an accord more transparent, creamier, drier, brighter, or deeper?
This guide explains what perfume raw materials really are, how they are classified, the difference between a raw material and an olfactory note, how to read technical information, and how to begin building a professional palette.

What are perfumery raw materials?
A perfumery raw material is a material used by a perfumer within a formula to produce an olfactory or technical effect.
It may be bergamot essential oil, jasmine absolute, a molecule such as Hedione®, a musk, a woody amber, a complex fruity base, or a solvent used to prepare a dilution.
It is important to understand one thing from the outset: an olfactory note is not necessarily a raw material.
When a perfume description mentions “pear,” “lily of the valley,” “leather,” “amber,” “sea breeze,” or “gardenia,” this does not necessarily mean that the bottle contains a natural extract of the named material.
Many notes are accords: effects built by the perfumer by combining several materials. A pear note may arise from the interaction of fruity, green, and floral molecules. A leather accord can be built with smoky, woody, animalic, and amber materials. A marine note may combine aquatic, ozonic, musky, mineral, green, and salty materials.
The professional question is therefore not only “which ingredient smells like this?”, but “which materials can I use to build this effect?” This is where the perfumer’s work begins.

What are the main raw materials used to create perfumes?
To navigate the palette, it is useful to organize it into four main groups.
| Type | What it is | Examples | Function |
|---|---|---|---|
| Natural raw materials | Extracts obtained from natural sources using appropriate processes | essential oils, absolutes, resinoids, CO₂ extracts | complexity, texture, natural signature |
| Aroma chemicals | Industrially produced substances and specialties | Hedione®, ionones, aldehydes, musks, woody ambers | structure, diffusion, precision, specific effects |
| Bases and accords | Professional blends that have already been constructed | floral, fruity, leather, and tobacco bases | creating or completing complex notes |
| Solvents and technical materials | Materials used to dilute, handle, or prepare a formula | ethanol, DPG, TEC | dilution, workability, finished product |
This classification is more useful than a simple “natural/chemical” opposition because it describes how the material actually functions in formulation.
1. Natural raw materials
Natural materials used in perfumery may come from flowers, leaves, peels, seeds, woods, roots, resins, and other sources. The extraction method profoundly changes the resulting product, so “natural” does not identify a single type of material.
Discover essential oils and natural perfumery materials →
Essential oils
Essential oils are obtained mainly through distillation or, in the case of many citrus fruits, by pressing the peel. Bergamot, lemon, orange, mandarin, lavender, and various woods and spices are classic examples.
An essential oil is not a single molecule. It is normally a complex mixture of many aromatic constituents and can therefore display several facets at once. Bergamot, for example, is not simply “citrusy”: it may appear green, floral, aromatic, bitter, and slightly spicy.
Absolutes
Some botanical materials are processed using extraction methods other than ordinary distillation, producing materials such as concretes and absolutes.
Absolutes are often exceptionally rich and distinctive. Jasmine, tuberose, and mimosa are classic examples. Here too, the name of the flower does not mean that the absolute is a perfect snapshot of the living flower: the extraction process selects certain components and produces a raw material with its own olfactory identity.
Resinoids, balsams, and resins
Benzoin, labdanum, frankincense, myrrh, and other resinous materials can create depth in amber, balsamic, woody, or gourmand accords.
Many of these materials are dense, viscous, or solid and may be supplied in a particular commercial form to make them easier to handle. This introduces a fundamental concept: the commercial form as supplied, which must not be confused with a recommended use level.
2. Aroma chemicals: the molecules of modern perfumery
Aroma chemicals are substances or specialties used to build, modify, and structure a composition. They can be obtained through different industrial processes, including chemical synthesis and, for some materials, biotechnology.
The term “synthetic” can be confusing: an industrially produced substance may correspond to a molecule also found in nature, or it may provide an olfactory effect for which no natural extract is available to the perfumer.
Synthesis has enormously expanded the palette. Modern musks, woody ambers, aquatic and ozonic materials, aldehydes, transparent floral molecules, and many highly diffusive specialties are all part of the language of contemporary perfumery.

To compare the function and behavior of some key modern materials, consider ISO E SUPER® TOCO IFF, Ambroxan Crystal (Kao), AMBROX® SUPER Firmenich, TIMBERSILK™ IFF, HEDIONE® Firmenich, and GALAXOLIDE® PURE IFF.
An aroma chemical is not “a cheap substitute for a natural”
This is one of the most common misconceptions. A synthetic molecule is not necessarily used to imitate a natural material, nor is it defined by being less expensive.
Hedione®, for example, can contribute brightness, airiness, and diffusion to a floral structure. A woody amber can build volume and presence in the base. A musk can change the texture of a formula, making it softer, cleaner, more enveloping, or more persistent. An aquatic material can introduce a sensation of air, water, or minerality without literally representing a natural extract.
This is why perfumers gradually learn to think of ingredients not only in terms of odor, but above all in terms of function.

3. Fragrance bases and accords
A fragrance base is a professional blend already constructed around a particular character. It may represent a flower, fruit, spice, texture, or abstract effect.
A Gardenia Base, for example, should not be interpreted as “gardenia oil”: it is a composition. The same logic applies to many fruity, floral, leather, or tobacco notes.
A base and an accord are not exactly the same thing
An accord may be a combination created by the perfumer within their own formula. A commercial base, by contrast, is a composed product developed and supplied as a raw material.
The perfumer can use a base as part of a formula and modify its character with other ingredients. A good base therefore does not eliminate creative work: it is another tool in the palette.

4. Solvents and technical materials
Not every material on a perfumer’s bench is intended to add an olfactory note. Ethanol, DPG, TEC, and other technical materials may be used to prepare dilutions, facilitate weighing and handling, or make the finished product.
It is essential to distinguish the fragrance concentrate formula from the preparation of the finished product. The perfumer may first develop the aromatic concentrate and then incorporate it into the carrier appropriate for the product type.

A perfume note may not exist as a natural extract
This point is essential to understanding perfumery.
When we perceive peach in a perfume, this does not necessarily mean that the perfumer used a “peach essence.” Many fruits do not yield, through ordinary extraction processes, an olfactory material capable of usefully reproducing the smell of the fresh fruit.
The same applies to several floral notes. Lily of the valley is a classic example of a constructed note. Effects such as gardenia, lilac, and freesia are also normally created through reconstructions and accords.
This is precisely where the difference between a raw material and olfactory language becomes clear: perfumers work not only with what nature allows them to extract, but also with what can be constructed.
Animal-derived materials and animalic notes: an important distinction
Historically, perfumery has used famous animal-derived materials such as musk, civet, and ambergris. In contemporary language, however, a musky or animalic note does not automatically imply the use of the historical animal material.
Modern perfumery has many synthetic musks and accords capable of creating animalic, warm, sensual, leathery, or salty effects. Here too, the name of the note and the technical identity of the ingredient are two different things.
How does a perfumer choose raw materials?
Beginners tend to choose like this: “I want a rose perfume, so I will buy something that smells like rose.”
With experience, the reasoning changes. The perfumer may ask: “I already have the rosy character. What is missing from the structure?”
Perhaps it needs more air, a green contrast, a spicy nuance, or a musky element that extends the sensation on skin. Or perhaps the heart is rich but static and needs a material that can open it up.
A raw material is therefore chosen not only for what it is, but for what it does when it meets the other ingredients. This is one of the decisive steps from simple mixing to composition.
Diffusion and persistence are not the same thing
“Strong,” “persistent,” and “diffusive” are not synonyms.
A material may remain on a blotter for a very long time yet diffuse relatively discreetly. Another may create a strong presence in the surrounding space without being the most persistent part of the base. A third may be extremely powerful even at very low dosage.
To assess a material, several dimensions must therefore be observed: intensity, diffusion, tenacity, character, and function in the formula.

Top, heart, and base: a useful map, not three rigid boxes
The olfactory pyramid is useful for introducing volatility, but it should not be interpreted as an absolute division. Raw materials evaporate in different ways, and their perception also depends on the formula, concentration, and interactions with other materials.
An ingredient may be perceptible during several stages of a fragrance’s evolution. In formulation, it is therefore more useful to observe the material’s actual time curve than to rely only on its theoretical classification.
How do you study a raw material?
Smelling a material once from the bottle does not mean knowing it. Useful work begins when it is observed over time.
A material should be evaluated on a blotter, at an appropriate concentration, and checked again at different intervals. Some materials are immediately legible; others change radically after several hours. Very powerful molecules can become easier to understand when studied in dilution.
It is useful to record not only “it smells woody”, but also its behavior: dry woody, amber, gradually warmer; increases the volume of the base; remains perceptible after several hours.
The second description is genuinely useful to a formulator because it explains what the material does.

Why are perfume formulas weighed instead of measured in drops?
A professional formula is normally constructed by weight.
A drop is not a sufficiently precise unit: dropper size, viscosity, temperature, and operator technique can all change the actual amount. Weighing allows the formula to be recorded and reproduced.
Reproducibility is essential when a trial becomes a real perfume, when successive modifications are compared, or when the same composition must be produced again.
Why are some materials diluted before they are studied?
Not all raw materials should be evaluated in the same way. Some are extremely powerful; some are solid or crystalline; others are viscous and difficult to dose.
Preparing a dilution can make a material easier to weigh and, above all, easier to read olfactorily. A study dilution does not mean that the material must be used at that same concentration in the final formula: it is a working tool.
What does 10%, 50%, or 55% in a raw material’s name mean?
A commercial material may be supplied pure or already in a particular commercial form.
If the manufacturer specifies a percentage concentration and a carrier, that information describes the product in its commercial form as supplied. It is not automatically a dosage recommendation for the formula.
Commercial concentration, study dilution, and percentage in the finished perfume are three different concepts.

CAS, trade name, and INCI are not the same thing
A professional data sheet may list several identifiers. The trade name identifies the quality or specialty with which the perfumer works. A CAS number is a chemical identifier used for substances and, in some cases, for descriptions associated with complex materials. INCI belongs to the system used to name cosmetic ingredients.
The manufacturer and commercial quality can be equally important. Two materials with the same CAS number should not automatically be considered identical from an olfactory standpoint.
A compound base, moreover, should not be treated as though it were necessarily a pure molecule identifiable by a single CAS number.

SDS, IFRA, and use percentage: three different things
This is one of the topics that creates the most confusion for beginners.
An SDS — Safety Data Sheet primarily describes the product’s classification, hazards, handling, storage, and safety information. It is not a formula and, by itself, does not answer the question “how much can I put in a perfume?”
IFRA information, where applicable, concerns standards for use in different categories of finished products. A manufacturer’s recommended use level, on the other hand, is formulation guidance and must not automatically be confused with an IFRA limit.
A perfumer must learn to keep these levels of information separate.
How to read an SDS · How to read IFRA Category 4
How can you tell whether a raw material is high quality?
Price alone says little. For professional work, the identity and traceability of the material are what matter most.
Where available, you should be able to determine who manufactures it, its trade name, the form in which it is supplied, its concentration, and the technical information associated with the product.
For natural materials, botanical origin, extraction process, and batch quality also become important. For a manufacturer’s specialty, the original trade name may be essential to identify the material precisely.
A raw material does not become professional because it is sold in an elegant bottle. It becomes a professional tool when we know what we are putting into the formula.
Read more: Why the same raw material can have different prices
Natural or synthetic: which is better?
It is an understandable question, but for a perfumer it is framed in the wrong way.
A composition is not automatically better because it contains more natural materials, nor automatically more modern because it contains more synthetics. The two categories offer different possibilities.
A natural material can bring extraordinary intrinsic complexity. A synthetic molecule can make it possible to control diffusion, texture, volume, or character with great precision. A professional chooses a material because the formula needs it, not because it belongs ideologically to one category or the other.
Nor does “natural” automatically mean “safer”: ingredients must be assessed individually according to composition, classification, applicable restrictions, and use in the finished product.

Two examples: how a note arises from composition
Building a floral effect
Suppose we want to create a floral effect. A beginner might simply look for a “flower essence.” A perfumer might instead build the body of the flower first, then add brightness, a green component suggesting the stem, a creamy nuance giving volume to the petals, a more indolic element to increase naturalness, and finally musky or woody materials linking the flower to the base.
The result can clearly evoke a flower without corresponding to a single botanical extract. This is the logic of an accord.

Creating a marine effect
The sea is not a bottle of “sea essential oil.” A marine accord can be constructed from very different materials.
Calone can introduce a marine-aquatic character with a distinctive melon facet. Other materials may bring air, ozone, floral transparency, minerality, salinity, or wet woods. By adding citrus, musks, green elements, or woody materials, the same aquatic core can become Mediterranean, mineral, tropical, cold, or abstract.
This is a perfect example of how a perceived note is the result of a composition and not necessarily the name of an ingredient.
Raw materials for aquatic and marine accords →
How many raw materials do you need to begin?
You do not need 300 bottles. In fact, an enormous palette can slow down learning.
It is more effective to begin with a limited group of materials that demonstrate different functions and to know them properly. A first palette should make it possible to compare at least floral, woody, musky, sweet, and fresh structures, including both natural and synthetic materials.
The initial goal is not to be able to create any perfume imaginable. It is to learn to answer questions such as:
- What happens if I increase this material?
- Which ingredient is creating volume?
- Which one makes the accord more transparent or denser?
- Which one connects the heart to the base?
- Which one completely changes the accord even in a minimal amount?
Once you begin to answer these questions, the palette stops being a collection of smells and becomes a composition tool.

Where can you buy raw materials for creating perfumes?
When buying formulation ingredients, especially online, it is useful to distinguish a genuine raw-material catalog from a generic assortment of “fragrance oils.”
Anyone who wants to learn composition should look for identifiable materials, clear technical information, and quantities suitable for study. A professional catalog may include specialties from international manufacturers, selected natural materials, bases, aroma chemicals, and solvents.
Small sizes are especially useful during study because they make it possible to build a palette without immediately purchasing industrial quantities. Larger quantities become relevant once a formula has been developed and the material is actually used in production.

How to begin creating perfumes professionally
The starting point is not buying everything. It is building a method.
- Study materials individually and over time.
- Compare materials from the same family.
- Build small accords with only a few ingredients.
- Work by weight and record every change.
- Evaluate the formula immediately, after several hours, and over the following days.
- Whenever possible, change one variable at a time.
An apparently minimal change can completely transform a composition. A perfumer’s laboratory is therefore not merely a place filled with bottles: above all, it is a system of observation, formulation, and olfactory memory.
Conclusion: raw materials are the alphabet, not the perfume
Knowing hundreds of names does not mean knowing how to compose.
Raw materials are the perfumer’s alphabet. Essential oils bring botanical complexity. Absolutes and resinoids introduce texture and depth. Aroma chemicals allow precision, diffusion, and new olfactory territories. Bases make it possible to work with structures that are already articulated. Solvents make it possible to handle different materials and products.
But an alphabet alone does not create a sentence.
Composition begins when the perfumer understands why a material should be present, what function it performs, and how it changes all the others. This is the difference between collecting ingredients and formulating a perfume.

Frequently asked questions about perfume raw materials
What raw materials are used to create perfumes?
The main categories are natural raw materials, aroma chemicals, bases and accords, as well as solvents and technical materials. A professional formula may combine materials from different categories according to the desired effect.
What is the main ingredient in perfume?
There is no single main olfactory ingredient that applies to every perfume. In a finished alcohol-based perfume, ethanol may represent a large part of the product, but its olfactory character comes from the concentrate composed of odorant materials.
What ingredients do you need to make a perfume?
Formulation requires odorant materials with different functions: natural materials, synthetic molecules, musks, floral, woody, amber and fruity materials, bases, and solvents where needed. The choice depends on the project and the structure you want to build.
Are synthetic perfume ingredients harmful?
Safety cannot be assessed by dividing ingredients into “safe natural” and “dangerous synthetic” materials. Safety depends on the substance, concentration, product type, exposure, and applicable rules.
Can a perfume be created using only natural ingredients?
Yes. Natural perfumery is a valid creative choice, but it involves a different palette and does not provide all the effects available in contemporary perfumery in the same way.
What is the difference between a note and a raw material?
A raw material is an actual ingredient in the formula. A note is the olfactory effect that is perceived or described. A note may come from a single material, but it very often arises from the interaction of several ingredients.
Where can professional perfumery raw materials be purchased?
It is best to choose suppliers that clearly identify their materials, provide the manufacturer, trade name, concentration, and technical documentation where available, and offer quantities appropriate for study or production.
