Fragrance
Perfume Concentration
Definition
The percentage of aromatic compounds (the 'juice') in a fragrance relative to alcohol and water. Eau de Cologne (EDC): 2–4% — lightest, 2–3 hours. Eau de Toilette (EDT): 5–15% — moderate, 3–5 hours. Eau de Parfum (EDP): 15–20% — strong, 5–8 hours. Parfum/Extrait: 20–40% — most intense, 8–24 hours.
Why it matters for dupe shopping
Budget dupes often sell as EDP at prices that suggest EDC-level concentration. Check the label: if a 50ml bottle costs $25–$35 and claims EDP, the aromatic compound cost alone makes that price impossible without severe quality compromise. Genuine EDP under $50/50ml typically indicates synthetic-only formulation at minimal concentration.
