Fragrance Concentration Levels Explained
Fragrance concentration levels, Eau Fraiche, Eau de Cologne, Eau de Toilette (EDT), Eau de Parfum (EDP), Parfum/Extrait, describe the percentage of perfume oil in the formula, directly affecting strength, longevity, projection, and price. Understanding these distinctions helps you choose appropriate concentration for your lifestyle, predict how fragrances will perform, compare value across products, and avoid frustration from buying wrong strength for your needs.
The Complete Fragrance Concentration Hierarchy
Concentration describes the percentage of perfume oil (aromatic compounds) mixed with alcohol and water. Higher percentages mean more intense smell, typically longer duration, and higher price per volume. The Full Spectrum (weakest to strongest): EAU FRAICHE (1-3% perfume oil): Characteristics Extremely light, barely-there scent Mostly water-based (vs.
EDT vs More Than Just Strength Differences
Most people assume EDT and EDP versions of same fragrance are simply "weaker vs. stronger" intensity. Reality is more nuanced, they often smell meaningfully different, with different note balances and character.

When purchasing decants, understanding concentration critically affects which size makes sense for your needs and how much value you're getting. Same ml amount performs very differently across concentrations.

What Is a Decant? (And Why It's Better Than Blind Buying)
A decant is a small portion of fragrance transferred from a full bottle into a smaller container, typically 1ml to 10ml. It's the smart way to test expensive niche fragrances before committing to full-size bottles.
Decant Sizes Explained (1ml vs 2ml vs 5ml vs 10ml)
Choosing the right fragrance decant size fundamentally depends on your specific testing goal, initial exploration vs. thorough decision-making evaluation vs. travel convenience vs. extended wearing before bottle commitment. Each size (1ml, 2ml, 3ml, 5ml, 10ml, occasionally 15ml) serves distinct purpose with practical advantages and limitations: 1ml offers quick sampling across multiple options without significant investment; 2-3ml provides weekend-length testing revealing more development; 5ml delivers optimal thorough evaluation (our most popular choice for informed bottle-purchase decisions); 10ml+ enables extended testing or serves as travel/backup bottles. Understanding the applications-per-milliliter math (roughly 10-15 sprays per ml depending on atomizer efficiency and nozzle design), how many applications constitute sufficient testing for different fragrance types (simple compositions vs. complex evolving fragrances requiring more wears), what contexts you need to test (daily work wearing vs. special occasions vs. seasonal appropriateness), your personal decision-making style (quick intuitive vs. methodical thorough), and cost-value optimization (balancing testing sufficiency against decant pricing) enables informed size selection matching your specific situation.
How Many Sprays Are in a 1ml / 2ml / 5ml / 10ml?
Understanding precise application capacity in each decant size, how many sprays per milliliter, how many full wearings each size provides, how long decants last with daily vs. occasional use, enables informed size selection matching testing goals and usage patterns. The fundamental calculation depends on atomizer efficiency (spray mechanism converting liquid to mist), individual application patterns (minimalist single-spray vs. generous 5-spray approaches), fragrance characteristics (viscosity affecting spray volume, concentration level influencing how many sprays needed for desired effect), and wearing contexts (full-day office requiring longevity vs. evening event allowing reapplication). Standard industry baseline approximates 10-15 sprays per milliliter (depending on atomizer design, nozzle diameter, pump pressure, liquid viscosity), with typical wearing application using 2-3 sprays (conservative minimal) to 4-5 sprays (moderate generous).
