Eau de Cologne, often abbreviated as EdC, denotes a specific concentration of fragrance oils within a solution of alcohol and water. Typically, this concentration ranges from 2% to 4%. The comparatively low concentration results in a lighter, fresher scent compared to perfumes or eau de toilettes. A classic example is the original Cologne created in Germany, known for its citrus-based aroma.
The appeal of this fragrance type lies in its refreshing and invigorating character. Due to its lower concentration, it provides a subtle and non-overpowering fragrance experience, making it suitable for everyday wear and warmer climates. Historically, this type of fragrance was associated with cleanliness and hygiene, often used as a revitalizing splash.
