Fragrance notes are descriptions of fragrances that are often sensed preceding the use of a cologne. Notes are divideded into three parts; top, middle plus base. Each refer to groups of smells that can be smelt with regard to the time subsequent to the application of the scent. These details are produced based on the knowledge of the vanishing period of the substances plus the use for which the fragrance is planned. That said, each class of note can compliment the rest. Hence it is not as simple to be aware of a individual note because they will vary over a period of time. For instance, the occurrence of a specific base or heart note will impact the aroma perceived when the top notes are strongest, and equally the bouquet associated with the base notes will often change based on the smell of the middle notes. The theory of notes is used for the most part to describe a cologne for marketing and pr purposes. Occasionally they are referred to by perfumers to illustrate the various phases of a scents smell to the layman. Top notes. These are the smells smelt immediately preceding the application of a aftershave. They consist of tiny, lightweight molecules that disappear speedily. Top notes are important to the promotion of a perfume as it is these that shape a person's opening opinion of a scent. They are usually described as fresh, sharp or assertive. The ingredients that lead to top notes are volatile, pungent in smell, and fade away rapidly. Citrus along with ginger are usual elements 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 middle of the fragrance's diffusion process. It is the bouquet of a perfume that appears just before the end of the top notes. Their role is to mask the frequently disagreeable first impact of the base notes, that turn out to be more appealing with time. Compunds used for a scent's middles notes are regularly more mellow and rounded. The middle notes can occur anywhere from 2 minutes to one hour later than the first use of the perfume. Rose and lavender are normal ingredients used to establish the middle notes. Base notes. The middle plus base notes jointly develop the key theme of a fragrance with the base notes showing immediately before the end of the middle notes. Base notes generate the strength and intensity of a perfume. Bass note components are frequently the fixatives used to hold and enhance 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 generally deep and rich and are not usually sensed until at least thirty minutes after the scent has been applied. This time frame is frequently referred to as perfume dry-down. Some of the longer lasting base note compounds can still be sensed in excess of twenty four hours after application. This for the most part applies to the animalic notes.
