By Huma Vance • August 29, 2026 • 4 MIN READ

Confused by the French terms on luxury perfume bottles? Here is your definitive guide to understanding concentration percentages, sillage, and projected longevity.

Understanding Aromatic Concentrations

When selecting fine fragrance, the label indicates the exact ratio of pure aromatic fragrance oils to cosmetic-grade alcohol solvent. Here is how they stack up:

The Four Primary Grades

Eau de Cologne (EDC): 2% to 4% oil concentration. Crisp and invigorating, lasting 1 to 2 hours.
Eau de Toilette (EDT): 5% to 15% oil concentration. Bright and airy, optimal for casual daytime wear, lasting 3 to 5 hours.
Eau de Parfum (EDP): 15% to 20% oil concentration. The industry standard for high luxury. Rich, expressive sillage lasting 8 to 12 hours.
Extrait de Parfum / Pure Parfum: 20% to 40% oil concentration. The rarest tier. Dense, deeply intimate, and enduring 24+ hours on fabrics.

The Elora Standard

All fragrances curated by Elora by Huma are bottled strictly at Eau de Parfum and Extrait de Parfum potencies (22% to 28% pure oil density), guaranteeing that your investment delivers unforgettable prestige from the moment you spray.
