What is perfume made of?

By Omer Siton, founder of PerfuMate · Updated 2026-10-06

A spray perfume is made of two things: a concentrate of aromatic materials, which is the smell, and the alcohol it is dissolved in, which carries it. The concentrate is a blend of natural extracts, such as essential oils and absolutes, and synthetic aroma chemicals, often dozens of them, and it is the smaller part of the bottle. A perfume oil swaps the alcohol for a carrier oil, and a solid perfume for wax and oil.

What is perfume made of?

Aromatic materials, which are the smell, a carrier that holds them, usually alcohol, and a few helpers, in very different amounts:

Aromatic materials, the concentrate. Natural ones are distilled, pressed or extracted from flowers, citrus peels, woods, resins, roots and leaves. Synthetic ones, called aroma chemicals, are made by chemists: some are molecules also found in nature, others give notes that no plant oil provides, such as the marine note of Calone 1951. On a label, the whole blend is one word: Parfum, or Fragrance.
The carrier: perfumer's ethanol for a spray, a carrier oil such as jojoba for a perfume oil, wax and oil for a solid.
Helpers, in small amounts: a solvent such as dipropylene glycol that strong materials are diluted in, and in some products an antioxidant, a preservative or a colorant. IFRA calls these functional ingredients.

The industry's own count shows how wide the palette is. The 2025 edition of the IFRA Transparency List, compiled from what IFRA's members report using, names 3,691 ingredients: 3,312 used for their smell and 379 functional ones. Being on the list records use; it is not a safety endorsement. PerfuMate's catalog describes 2,211 perfumery materials, each with its smell, families and strength, and its strip life where one is known.

Is perfume made from flowers? Partly. Floral is the largest family in the catalog, but only about one in five of the materials filed as floral first is a natural extract; the rest are aroma chemicals and compounded bases. Some floral notes are built entirely from aroma chemicals: PerfuMate's Lilac Accord and Muguet Accord contain no natural material at all.

What is the main ingredient in perfume?

Alcohol. In a spray perfume the concentrate is the smaller share and perfumer's ethanol, usually denatured so that it cannot be drunk, is the rest. In the 30 ml example PerfuMate uses throughout, a bottle at 18 percent is 4.5 g of concentrate and 20.5 g of alcohol, so the alcohol is more than four fifths of it by weight. How small the concentrate's share is defines the concentration: the concentrations, explained.

Inside the concentrate, the biggest lines are often quiet, slow materials that give body and a long drydown, rather than the notes a description names: in the first formula on how to make perfume at home, the largest line is Hedione, 3 g of the 10. Across the 50 accords PerfuMate publishes on /accords, the most frequent material is Hedione, a transparent jasmine, in 26 of them, followed by the musk Ethylene Brassylate in 23.

Which chemicals are used in perfume?

Aroma chemicals, the single molecules perfumers buy at a known purity, and the same molecules arriving inside natural oils. A few that turn up in many formulas:

Hedione: a transparent, radiant jasmine.
Iso E Super: a smooth, velvety woody-amber.
Ambroxan: dry, warm ambergris.
Galaxolide and Ethylene Brassylate: clean, powdery musks.
Vanillin and Coumarin: the sweet base of vanilla and of hay and tonka.
Linalool and limonene: fresh floral and citrus, and also major molecules of lavender and of citrus peel.

That last point is the important one. An essential oil is a mixture of molecules, and the catalog lists the main ones for most of them: lavender carries linalool and a trace of coumarin, clove carries eugenol, tonka absolute carries coumarin. The IFRA Standards and the EU allergen rules follow the molecule wherever it comes from, so an oil can carry the same limits and labelling duties as the pure chemical. Aroma chemicals vs essential oils goes further.

Are perfume ingredients natural or synthetic?

Both, and most perfumes mix them. Naturals bring depth and a rough, living texture; aroma chemicals bring the same smell batch after batch, radiance, and notes nature does not give, including the clean musks and the ambergris molecules. On IFRA's Transparency List, 1,021 of the 3,691 entries are natural complex substances, the industry's term for an oil, absolute or extract made of many molecules. In PerfuMate's catalog, about one material in five is natural.

Natural does not mean safer or unrestricted, and synthetic does not mean harsh: safety belongs to each molecule and its dose. How to make natural perfume shows what a naturals-only formula can and cannot do.

How is perfume made, from raw material to bottle?

In three stages, often by three different companies: the raw materials are made, a perfumer composes a concentrate from them, and the concentrate is reproduced and put into the product. First the raw materials: naturals are harvested and distilled or extracted, often where they grow, and aroma chemicals are synthesised. Then a perfumer composes a formula, a concentrate of dozens or hundreds of these materials written to a client's brief and checked against the IFRA Standards. Finally the concentrate is reproduced to the formula by weight and dosed into the product; for a fine fragrance, that means diluting it in alcohol. IFRA describes industrial blending as automated, precise to parts per million and run under Good Manufacturing Practice.

At home the same sequence fits on a table:

Weigh the concentrate on a 0.01 g scale, material by material.
Dilute it in perfumer's alcohol to the strength you want.
Let it rest, cool, dark and sealed: about 60 days for an eau de toilette, 90 for an eau de parfum and 120 for an extrait on PerfuMate's schedule.
Chill it for a day, filter it and bottle it.

How to make perfume at home walks through each step with a first formula, and how long to macerate perfume covers the rest.

What does the ingredient list on a bottle tell you?

The carrier and a few named allergens, not the formula. In the EU, the whole blend of aromatic materials is written as the single word Parfum, and only the declarable fragrance allergens it contains are named in the list as well, once they pass the threshold for the product. In the US, fragrance ingredients can be listed simply as Fragrance, and the FDA notes that fragrance formulas are among the cosmetic components most likely to be trade secrets. So a line such as Alcohol Denat., Parfum (Fragrance), Limonene, Linalool, Coumarin tells you the carrier and a few named allergens, not the formula.

The named allergens do hint at the naturals inside: limonene and linalool often arrive from citrus oils and lavender, coumarin from tonka. How to label a perfume for sale reads the list line by line, and the allergen index shows which materials carry each allergen.
