Meaning and Differences Between Perfume EDT and EDP — Is Fragrance Concentration More Than Just Different in Concentration?

You have probably hesitated between perfumes with the same name at a perfume store. One of them Eau de Toilette (EDT), in the other one Eau de Parfum (EDP)It says that, and there is quite a difference in price.

To start with the conclusion, these two words are the ratio of the fragrance concentrate. ‘The rate of incense consumption’It refers to the difference, and accordingly, the characteristics of the scent are divided as follows.

Many people are prone to dismissing it by thinking, “Isn’t the stronger one (EDP) more expensive and better?”.

However, not only is the concentration of the fragrance oil increased, but the perfumer also 'tunes' the blend to match the concentration. Therefore, even perfumes with the same name can feel like EDT and EDP have completely different scent characteristics.

Today, starting with the concept of perfume concentration, or fragrance percentage, we will look at the practical differences between EDT and EDP.,

Let's explore, one by one, how perfumers redesign fragrances by concentration, and the reasons why preferred concentrations differ across cultures.

What is fragrance ratio?

The composition of the perfume is simpler than expected.
Flavoring concentrateand ethanol (alcohol), and a small amount of water. These three are all there is.

Here, fragrance concentration refers to the proportion of the fragrance concentrate within the total perfume solution.

French perfumer Jean-Claude Ellena described this as an 'aesthetic choice'.
This is because even when using the same ingredients, the way the fragrance unfolds on the skin changes completely depending on how the concentration is set.

Abbreviations like EDT and EDP written on perfume bottles are classifications based on this fragrance concentration.
The higher the proportion of fragrance, the stronger the scent, the longer the longevity generally, and the higher the price.
However, a high fragrance concentration is not an absolute standard that implies a 'better perfume'.
(This subtle correlation will be discussed in detail later.)

From Eau de Cologne to Extrait — A History of Concentration

The concentration system of perfumes was naturally formed over hundreds of years as technology and culture for handling fragrances accumulated.

In ancient times, burning incense was a ritualistic act offered to the gods. The word 'perfume' itself is Latin. per fumum, The fact that it came from the meaning of 'through smoke' proves this.

Later, as alcohol distillation technology developed in medieval Arabia and Europe, the culture of turning fragrances into liquid and spraying them directly onto the body finally began.

The lineage of perfume concentration that began in Cologne

1709, Italian perfumer Johann Maria Farina unveiled a groundbreakingly light fragrance combining citrus and herbs in Cologne, Germany.

This is 'Eau de Cologne (Cologne),' the origin of the modern perfume concentration system.

In French Eau de CologneIt means 'water of Cologne,' and is a rare case where the city name became synonymous with perfume.

There is a record that Napoleon loved this Eau de Cologne so much that he used 60 bottles a month.

Eau de cogne of that time was not just a simple perfume ‘Aqua Mirabilis (Miracle Water)’It was called [it] and was regarded as a panacea for hygiene and health.

People not only applied this to their bodies, but also dipped it in sugar and ate it, or poured the whole thing into their bathwater.
Subsequently, the 19th-century Industrial Revolution and synthetic fragrance With the advancement of technology, perfumes began to be mass-produced.

In this process, it became necessary to establish industrial standards to distinguish uses and durations based on the concentration of fragrance, and,
The systematic classifications we use today—Eau de Cologne, Eau de Toilette, Eau de Parfum, and Extrait de Parfum—have been established.

EDT, EDP, Perfume — Comparison of Differences by Concentration

The classification of perfumes by concentration is summarized as follows. However, please note that these figures are industry conventions and not legally mandated standards, so they may vary depending on the individual perfume.

In fact, even perfume experts define the range of fragrance concentration slightly differently.

Luca Turin summarized that EDT is approximately 101 TP3T, EDP is 15–181 TP3T, and Perfume is 251 TP3T or higher.

On the other hand, Nigel Groome’s *The Perfume Handbook* describes EDT as 4–81 TP3T and EDP as 15–181 TP3T, so there are differences in ranges depending on the source.

Jean-Claude Elena also explained that there is an overlapping section between EDT 5~20% and EDP 10~20%.

As the boundaries of concentration are not clear, the labeling may vary depending on the brand's marketing strategy.

A representative example is Jo Malone London (Jo Malone London)Examples include this. They call almost all of their products 'Cologne,' but the actual fragrance concentration is at or above the level of a standard Eau de Toilette (EDT).

In fact, Jo Malone London perfumes, which are famous for their short lasting power, are often mistaken for Eau de Cologne due to their name.

This is not cologne as a technical term meaning low concentration, but rather to emphasize the brand's identity of a 'light and modern style'. Marketing nameIt is.

Comparison table by concentration

Looking at the sales ratio of women's perfumes in the French perfume market, Eau de Toilette accounts for 501 TP3T and Eau de Parfum accounts for 451 TP3T.

On the other hand, in the men's market, Eau de Toilette accounts for 901% of the total. Men's perfume extrait is still quite rare.

Why does the same perfume feel different? — The perfumer's concentration design

Many people understand the difference between EDT and EDP as a difference in concentration, or 'strength'.
It is easy to think like this: if you add more of the same concentrate, it's EDP; if you add less, it's EDT.

However, in reality, there are quite a few cases where that is not the case.

In most cases, there is no difference in the composition of fragrance oils used in EDT, EDP, and perfume.

However, houses like Hermès and Cartier sometimes use higher proportions of more expensive ingredients in their perfume versions, and in the case of Chanel No. 5, completely different compositions are used depending on the concentration.

The Difference Between EDT and EDP as Seen Through Chanel No. 5 and Dior Sauvage

Chanel No. 5The case of is the most dramatic example.

It is known that jasmine from the Grasse region of France is used exclusively in the perfume version, and the rich, deep texture created by this ingredient is difficult to experience in the EDT or EDP.

While No. 5 in EDT gives a bright and cheerful impression, the perfume can feel like a completely different fragrance.

Dior Sauvage The line shows another method of concentration design.

The EDT released in 2015 features a sharp opening of bergamot and Sichuan pepper.

On the other hand, in the 2018 EDP version, the pepperiness is significantly softened, and smoky vanilla and star anise are added, giving it a warmer and softer character.

An interesting point is that in the case of Sauvage, there are many user opinions that EDT is actually stronger than EDP in terms of silage (diffusing power).

A higher concentration does not necessarily mean it spreads more strongly; rather, the higher the concentration of the perfume, the more it tends to adhere to the skin and spread subtly.

This is precisely why perfumers regard concentration not as a tool for 'controlling intensity,' but as a tool for designing the character of the scent itself.

EDT in Asia, EDP in the U.S.? — Concentration determined by culture and body odor

Preferences for perfume concentration go beyond mere taste and show distinct differences depending on the region's climate and people's **genetic traits (body odor)**.

Asia, especially Korea and JapanThey have traditionally preferred low-concentration EDTs or colognes. This is closely related to their genetic physical characteristics of having less body odor compared to Westerners.

Because there is no need to mask body odor, strong perfumes tend to be perceived as 'harsh' or 'artificial'.

Also, due to a culture of high population density and frequent use of public transportation, not invading others' space ‘A subtle scent like the smell of skin’Skin scent is considered a virtue.

the other side US and European marketsThey prefer a concentration strong enough not to be overpowered even when mixed with their body scent. This is because they have high expectations that the perfume should act as an 'invisible garment' that clearly makes their presence known throughout the day.

Especially in the U.S., the scent spreads far even in large spaces ‘Sillage’There is a tendency to use this as a measure of perfume performance, so concentrated EDP or perfume grades are sold as the main products.

These differences also affect the brand's global strategy.

When targeting the Asian market, global brands often launch "Asia-exclusive" light versions with reduced concentration or prominently feature EDT lineups that emphasize clear and watery notes.

Concentration and Longevity — Fragrance Rate Is Not Everything

“The saying that "a higher fragrance content lasts longer" is generally true, but not always.
This is because concentration is not the only factor determining persistence.

The real factors determining longevity

The longevity of perfume is fundamentally Volatility of fragrance moleculesIt depends on.
Fragrances are classified into top notes, middle notes, and base notes according to their evaporation rate.
It explains that top notes disappear within 6 to 18 hours, middle notes last 24 to 48 hours, and strong bass notes like civet or patchouli remain on the blotter for several days or more.

This means that perfumes composed mainly of citrus notes may have short longevity, no matter how high the fragrance concentration.

Conversely, Wood, Musk, Fragrances that are solidly supported by heavy base notes like amber leave a sufficient lingering scent even at a low concentration.

This is explained more scientifically through the concept of 'substantivity' of fragrances.

How well fragrance molecules adhere to and remain on the substrate called skin is determined by their molecular weight, vapor pressure, and physicochemical affinity with the skin surface.

Choosing the right concentration for the situation

Ultimately, the most important question will be, “What is the right concentration for me?”.
There is no single right answer, but establishing a few criteria makes the choice much easier.

EDT for commuting and daily activitiesIt is convenient. It does not burden the surroundings even after a light spray, and if necessary, you can spray it once more during the day.

If you use a refreshing citrus or green-based perfume, the EDT suits that character well.

For dinner appointments or special occasions, EDPIt is a good choice. Once sprayed, a subtle lingering scent remains until the time you leave work, and because the fragrance unfolds more richly than an EDT, you can fully experience the story of the perfume.

Perfume or Extravaganza for time just for myselfLet's try this.

When applied to the skin in small amounts, it slowly releases due to body temperature, allowing you to feel layers of fragrance that are detected only at the most intimate distances.

Because the higher the concentration of the perfume, the deeper the reaction with the skin's chemistry, the same perfume shows different textures for each person.
