Sprays / Concentration
What determines which category a perfume belongs to is its concentration of odorous materials. This is because perfume is composed of a concentrate that has been diluted in alcohol. A concentrate is a mixture of pure raw materials: essential oils, natural absolutes, and/or synthetic substances :
Eau de toilette remains the least concentrated solution, with a percentage between 8% and 10%.
Eau de parfum has a percentage of essences between 10% and 20%.
Perfume, also known as “essence” or “extract” is the most concentrated preparation, with a percentage between 20% and 30% of raw materials diluted in alcohol.
The higher the concentration in a fragrance, the more results you get for a longer lasting and more aromatic application.
