Perfumery notes are descriptions of perfumes that tend to be detected preceding the application of a scent. Notes are divideded into three parts; top, middle plus base. Each refer to groups of smells that can be sensed with regard to the moment in time following the application of the scent. These notes are produced with the knowledge of the evaporation period of the elements as well as the function for which the perfume is planned. That said, every class of note can compliment the others. So it is not as simple to be aware of a distinct note as they continually alter over a period of time. For example, the occurrence of a certain base or middle note will effect the smell perceived when the top notes are strongest, and similarly the smell linked with the base notes will frequently vary based on the fragrance of the middle notes.
The theory of notes is used mainly to explain a aftershave for marketing, pr and advertising purposes. Occasionally they are referred to by perfumers to portray the different phases of a scents aroma to the layman.
Top notes.
These are the aromas smelt instantly upon the application of a scent. They consist of minute, lightweight molecules that disappear speedily. Top notes are key to the selling of a scent as it is these that form a person's first view of a fragrance. They are typically described as fresh, sharp or assertive. The ingredients that lead to top notes are volatile, strong in aroma, and fade promptly. Citrus in addition to ginger are common ingredients for top notes. Top notes are occasionally referred to as the head notes.
Middle notes.
Sometimes known as the heart or main body of a fragrance, they emerge in the central point of the fragrance's diffusion process. It is the bouquet of a fragrance that appears just before the last part of the top notes. Their role is to mask the often unpleasant first impact of the base notes, which become more appealing with time. Compunds used for a scent's middles notes are usually more mellow and rounded. The middle notes can appear anywhere from two minutes to one hour following the initial application of the perfume. Rose in addition to lavender are typical compounds used to form the middle notes.
Base notes.
The middle plus base notes collectively create the central theme of a fragrance with the base notes appearing immediately before the departure of the middle notes. Base notes make the strength and intensity of a scent. Bass note components are often the fixatives used to support and boost the intensity of the lighter middle and top notes. The molecules contained in these compounds are sizeable and heavy which mean they evapourate slowly. These compounds are commonly deep and rich and are not usually sensed until at least 30 minutes after the cologne has been applied. This time frame is often referred to as perfume dry-down. Several of the long lasting base note ingredients can still be sensed in excess of twenty four hours after application. This particularly applies to the animalic notes.
