Fragrance products are categorized based on the concentration of aromatic compounds they contain. Parfum, also known as extrait de parfum or perfume extract, represents the highest concentration, typically ranging from 20% to 30% of perfume oils. Eau de toilette, conversely, features a lower concentration, generally between 5% and 15%. This difference in concentration significantly impacts the longevity and intensity of the scent. For example, a perfume might last for six to eight hours on the skin, while an eau de toilette may fade after two to three hours.
The degree of concentration determines both the price point and the intended use of the fragrance. Higher concentrations, such as in perfumes, often command a premium due to the greater amount of expensive fragrance oils used in their formulation. These are often reserved for special occasions or evening wear due to their potent and long-lasting nature. Lower concentrations, like eau de toilette, are generally more affordable and appropriate for everyday wear, offering a lighter and more subtle scent profile.
