The difference between EDT, EDP, Parfum and Extrait is concentration: how much fragrance oil is in the bottle. Eau de toilette (EDT) is lightest, eau de parfum (EDP) is stronger, and parfum or extrait de parfum is the most concentrated everyday format. More oil means more projection and longer wear. It is the single most useful thing to understand before buying a fragrance, because it decides how long the scent actually lasts.
Quick answer: EDT (5-15% oil) is light and fresh. EDP (15-20%) is stronger and longer-lasting. Extrait de parfum, also called parfum (20-40%), is the most concentrated and longest-lasting of the everyday formats. If longevity is what you care about, the label to look for is extrait.
Concentrations compared
| Format | Typical oil | Longevity | Character |
|---|---|---|---|
| Eau de cologne (EDC) | 2-4% | 1-2 hrs | Very light, splash-on |
| Eau de toilette (EDT) | 5-15% | 3-5 hrs | Fresh, brighter opening |
| Eau de parfum (EDP) | 15-20% | 5-8 hrs | Rounded, most common |
| Extrait / Parfum | 20-40% | 8+ hrs | Richest, closest to skin, longest |
Ranges are industry guidelines and vary by formulation. Larcin sits at 30%, in the extrait band, across the whole range.
Is Parfum the same as Extrait de Parfum?
Yes. "Parfum," "pure parfum" and "extrait de parfum" all refer to the same most-concentrated format. It is the strongest everyday strength, richer and longer-lasting than EDP, and because it is potent you use less per application.
Which should you buy?
For longevity and value per wear, higher concentration wins, which is why designer houses reserve extrait for their most intense releases. If you want a scent that lasts through a full day, extrait de parfum is the format to choose. Larcin builds every fragrance at 30% for exactly this reason. The deeper explanation is in what is extrait de parfum.
Frequently asked questions
What is the difference between EDT and EDP?
Concentration. EDT is 5-15% fragrance oil and lighter. EDP is 15-20%, so it projects more and generally lasts a few hours longer than EDT.
What lasts longer, EDP or Parfum?
Parfum (extrait de parfum) lasts longer. At 20-40% oil it is more concentrated than EDP's 15-20%, so it projects and stays detectable for longer.
What concentration is Larcin?
Larcin is 30% concentration, the extrait de parfum band, across the whole range, in a 50ml bottle for a flat $50 AUD.
Does higher concentration always last all day?
Higher concentration is built for longer wear, but exact time still depends on skin type, climate and how much you apply.
The verdict
Concentration is the number that decides projection, longevity and value per wear. If longevity matters, choose extrait de parfum, which is exactly what Larcin is. See the range in best dupe perfumes in Australia or the longest-lasting picks.
