EDP vs Extrait: What Does Concentration Actually Change?

The abbreviation on a fragrance label actually reveals its character. The difference between EDP (Eau de Parfum) and Extrait (Extrait de Parfum) is, contrary to what many assume, not simply a matter of ratio. Let us establish the definitions first.

Fragrance concentration refers to the weight ratio of the fragrance oil (the aromatic concentrate) within the total mixture. EDP is generally accepted to contain approximately 10–20% fragrance oil. Extrait sits at 20–30%, sometimes higher. The remainder is largely alcohol (ethanol), a small amount of water, and where necessary, appropriate solvents.

But let us state this upfront: Concentration alone does not determine performance. What truly governs how long a fragrance lasts and how far it projects is the volatility (rate of evaporation) of the raw materials within it. This is why it is incorrect to say "extrait always lasts longer." When the top notes have gone, the base takes over the stage; the weight of that layer — not the concentration — is the formula's backbone.

The table below is a signpost, not an absolute rule. Brands stretch these bands according to their own formulas. We have deliberately given ranges for longevity and projection figures, because the formula determines reality far more than the ratio does.

Note: a higher ratio does not automatically mean stronger sillage (the trail a scent leaves behind). A citrus-heavy 25% extrait can fade within an hour because of its rapid evaporation. By contrast, an amber-, oud-, musk- and resin-heavy 12% EDP can sit on skin for hours — because those raw materials are heavy and evaporate slowly.

Before raising your concentration, take a step back and look at your formula's note pyramid. That is where performance is won or lost.

A fragrance is built from three layers: top notes (volatile, the first impression), middle/heart notes (the body), and base notes (the heavy, lasting foundation). Extrait formulas generally contain not just more fragrance oil, but also more base notes. That is precisely what creates the sense of longevity — not a high ratio, but the density of heavy molecules.

From a producer's perspective, extrait means "more fragrance oil = higher cost." But the story does not end there; practical considerations such as solubility, maceration and density also determine cost and quality.

Cost: When you raise the fragrance oil ratio from 12% to 25%, you roughly double the share of your most expensive ingredient. With a costly raw material, this pushes the retail price up significantly. This is why extrait demands premium positioning — otherwise it makes no economic sense.

The solubility trap: Dissolving the fragrance oil in a high-concentration extrait can become difficult. The risk of cloudiness and phase separation increases. Adding a lot of water to high-proof ethanol makes this problem worse. Keep the water proportion low, start with minimal water, test for clarity, and use a ready-made perfumer's alcohol or a suitable solvent if necessary. For solvent selection, the article "DPG vs IPM: Which Solvent and When?" will be useful.

Maceration: This is not simply "leaving the mixture to sit" — it is the process of allowing the alcohol and fragrance oil to interact, and the scent to settle through esterification. Maceration (at room temperature, approximately 15–20 °C), protection from light, and then cold filtration (to remove waxy substances) soften the harsh "alcohol hit" on first spray. This step is even more critical in dense formulas such as extrait.

In summary: choosing between EDP and extrait is not a question of "which one is stronger." It is a question of which character you want to deliver, at which price point, to which audience. Build the structure first, then choose the concentration. The rest is your signature.

One more note: raising the concentration also opens up new calculations on the IFRA side. Limits are set not by total fragrance oil percentage but by individual ingredients, allergens and product category (leave-on / rinse-off). Do not assume that "it's an extrait at 25%, so it's safe" — always read the fragrance oil's IFRA compliance statement and build your formula accordingly.
