The Art of Fragrance
Fragrance, or perfume, is a mixture of natural or synthetic substances that emits a pleasant smell upon application to the skin. Perfumes have been worn throughout history and are used in many industries from the fashion sector to food service and manufacture of scented household products. The job of composing perfumes and smelling substances that appeal to consumers is known as fragrance composition, and it is the duty of an expert in the field who is often called a “perfumer”. The art of combining and producing fragrance compositions is sometimes compared to the skill of playing musical instruments. This is because a harmonious scent accord is made up of three sets of olfactory components that unfold in time, beginning with the top notes which are then followed by the middle notes and finally the base notes. The top notes are the first scents a person perceives, usually within two minutes of applying a perfume, and they are composed of small, light molecules that evaporate quickly. Middle notes are a little longer-lasting than the top notes and are based on a variety of aromatic compounds that give a perfume its heart. Base notes are the scents that remain for an hour or more and are composed of larger aromatic compounds. Historically, fragrances have been derived from flowers, herbs and spices that can be extracted by distillation or synthesis. Modern fragrance technology allows the creation of complex scents with a large number of different aroma chemicals. Perfumers use these chemical components to make perfumes that can be marketed as eau de parfum, eau de toilette, or eau de cologne. The concentration levels of these perfumes are determined by the amount of aromatic compound in each bottle: the higher the concentration level, the more intense and lasting the perfume. A perfume can be classified according to a specific scent family such as floral, woody, or fruity. However, the naming of fragrance families is not objective or definitive and many perfumes contain aspects of multiple scent groups. Additionally, even a fragrance composed of a single aromatic substance may have subtle undertones of other chemicals in the perfume’s composition. In recent research, it has been found that the way a person smells is important to women in their choice of a romantic partner. This is especially true for men, who are more likely to be chosen by a woman if they have a pleasant smell. The reason that women choose certain fragrances is not fully understood, but it has been speculated that their mood may influence their preferences. Perfumes that evoke memories of a happy or positive event are popular choices among women. Studies have also shown that perfumes can influence a person’s behavior in some ways, such as making her more attractive to men or improving her chances of being selected for a date. It has been suggested that this behavior is a subconscious reward for the sensory pleasure of a pleasant smell.
