    Understanding Fragrance Strengths & Perfume Oil Concentrations

    Fragrance strengths and perfume concentrations play a vital role in the world of perfumery. These terms are closely intertwined, referring to the concentration of raw material oils within a fragrance. The varying concentrations have a direct impact on the scent's sillage, projection, and other characteristics.

    The quality and blending techniques employed by different brands can lead to interesting variations in perfume performance. It's not uncommon to discover that an eau de toilette can project more strongly than an eau de parfum. This is due to the way the perfume oil interacts with the surrounding environment when it is diluted with alcohol in the fragrance bottle. 

    It's amazing to think the performance of EDT vs EDP can sometimes be so very different indeed, more than a case of adding a little more oil into the mix.

    Moreover, it's important to note that many western-style perfumes are not composed solely of fragrance essence. They often include additional ingredients such as perfumers alcohol, purified water, perfume oils, and aromatic compounds. These elements contribute to the overall composition and character of the fragrance.

    Strength Variants

    Below is our perfume strength guide, where you will understand the differences in fragrance oil concentrations per variant, what that means for performance, but also price.

    Eau Fraiche:

    🇫🇷 Meaning - "Fresh Water"

    • Eau Fraiche has the lowest concentration on the market, around 1% to 3%.
    • Great for a very quick refresh of a short burst of fragrance, lasting 1 to 2 hours.
    • The cheapest variant on the market due to low fragrance concentration and longevity.

    Eau de Cologne (EDC):

    🇫🇷 Meaning - "Water From Cologne"

    • It has a light and refreshing scent that lasts for a short duration, usually up to 2 to 3 hours.
    • EDC is very inexpensive variant due to its low fragrance concentration.

    Eau de Toilette (EDT):

    🇫🇷 Meaning - "Grooming Water/Toilette Water"

    • EDT contains a higher concentration of fragrance oils than EDC, usually between 5% and 15%.
    • It offers a moderately lasting scent, typically lasting around 3 to 4 hours.
    • EDT is a popular choice for daily wear and is more affordable compared to higher concentrations.

    It is extremely important to understand that perfumes can vary in their performance due to the unique composition of aromatic compounds used in each individual fragrance.

    Interestingly, you may come across lower concentration perfumes that perform just as well, if not better, than those with the highest concentration, such as Extrait de Parfum.

    The reason behind this lies in the fact that the perfume industry does not have standardised intensity levels for different perfume concentrations. Therefore, the performance of a fragrance cannot be solely determined by its concentration.

    This underlines the importance of utilising fragrance samples when embarking on the journey of discovering your next signature scent, as it is relatively inexpensive vs the cost of a full-sized bottles.

    Perfume 101: Longevity vs Sillage vs Projection

    EDT vs Eau De Parfum... does strength really matter that much?

    We certainly think it does - perfume and aftershave strengths no longer follow the same composition like the good old days. There's now so many variables to pay attention to when buying a fragrance.


    Perfume concentrations have become increasingly diverse. Circling back to the the importance of perfume samples - it's crucial to conduct a thorough "test-drive" of a fragrance and allow it to settle for at least 30 minutes. This gives the perfume time to develop and reveal its true longevity.

    Certain fragrance notes, such as patchouli and amber, tend to have a longer-lasting effect compared to citrus and aquatic notes. Many modern popular releases lean towards a milder scent profile. If you're seeking better performance in terms of longevity, starting with an Eau de Parfum fragrance would be a wise choice.

    Projection & Sillage

    Although closely related, projection and sillage hold distinct meanings in the world of perfumery. Projection refers to how far the scent radiates from your body, while sillage pertains to the lingering trail or scent bubble you leave behind.

    Eau de Toilettes, with their higher alcohol concentration, generally have a stronger projection compared to more concentrated forms like Eau de Parfum or Pure Perfume scents.

    Unfortunately, misconceptions often arise regarding this important aspect of fragrance purchase. Higher perfume concentrations primarily enhance longevity rather than projection and sillage. It's important to consider your preferences and desired effect when choosing the right concentration for your needs.


    Variations Between Perfume Lines
