Scent notes are descriptions of perfumes that might be detected after the application of a scent. Notes are divideded into 3 parts; top, middle and base. All refer to groups of aromas that can be smelt with regard to the moment following the application of the perfume. These explanations are formed with the knowledge of the disappearance time of the elements in addition to the purpose for which the fragrance is planned. That said, each class of note can impact the rest. So it is not as easy to get the impression of a specific note because they will alter over a period of time. For example, the occurrence of a individual root or middle note will compliment the aroma perceived when the head notes are strongest, and likewise the aroma associated with the base notes will often change depending on the smell of the middle notes. The concept of notes is used principally to explain a scent for advertising reasons. Occasionally they are referred to by perfumers to portray the several stages of a scents aroma to the layman. Top notes. These are the smells smelt immediately after the application of a fragrance. They comprise of minute, light molecules that evaporate quickly. Top notes are vital to the selling of a cologne as it is these that create a person's initial opinion of a cologne. They are usually described as fresh, sharp or assertive. The compounds that lead to top notes are volatile, pungent in smell, and fade away swiftly. Citrus and ginger are frequent compounds for top notes. Top notes are occasionally referred to as the head notes. Middle notes. On occasion known as the heart or main body of a fragrance, they emerge in the focal point of the fragrance's diffusion process. It is the aroma of a fragrance that appears just ahead of the closing stages of the top notes. Their function is to mask the frequently disagreeable first impression of the base notes, which grow to be more appealing with time. Compunds used for a scent's middles notes are mostly more soft and rounded. The middle notes can materialise anywhere from two minutes to 1 hour later than the first application of the fragrance. Rose and lavender are usual ingredients used to form the middle notes. Base notes. The middle plus base notes collectively form the major theme of a fragrance with the base notes showing just before the departure of the middle notes. Base notes form the strength and intensity of a scent. Bass note ingredients are often the fixatives used to hold and boost the intensity of the lighter middle and top notes. The molecules contained in these compounds are big and heavy which indicate they evapourate slowly. These compounds are usually deep and rich and are not generally sensed until at least 30 minutes after the scent has been applied. This time period is regularly referred to as perfume dry-down. A quantity of of the long lasting base note compounds can still be sensed in excess of twenty four hours after application. This particularly applies to the animalic notes.
