Here’s the basic understanding on EDC, EDP, EDT and the other scent language that labels often confuse us with —
Eau de Cologne: Eau de Cologne is three to five percent perfume oil in a mixture of alcohol and water. It tends to be lighter and refreshing, typically with a citrus oil component.
Eau de Toilette: Eau de Toilette contains a slightly higher percentage of perfume oil, and is mixed with alcohol instead of water, making it more fragrant.
Eau de Parfum: With a higher percentage of perfume oil (roughly 15% to 18%), mixed with alcohol, Eau de Parfum is heavier than Eau de Cologne and Eau de Toilette, but lighter than Perfume.
Perfume: With 15% to 30% perfume oil mixed with alcohol, perfume contains the highest percentage of oil, making it the most concentrated and potent.
