Our range of Fragrances covers different classes of products, each class has a different concentration of perfume oil which affects the cost. Perfume oils are the expensive ingredient in fragrances and when the concentration is higher this increases the presence of the perfume or sillage (how far the fragrance extends from your body) and how long the fragrance lasts through the day. Eau de Parfum (EDP) has the highest concentration of perfume oils, between 15 and 20 percent. They are made to last on the skin all day and are more expensive, but you need only a small amount to achieve the effect. Eau de Toilette (EDT) have a lower concentration of perfume oils, around 5 to 15 percent. Eau de Cologne usually refers to masculine scents which have a still lower concentration, usually around 2 to 4 percent perfume oils and contain more alcohol.
