Perfume is made up of alcohol combined with a fixative, essential oils or chemical scents. Cologne is essentially a diluted version of perfume. Perfumes generally contain up to 30% essential oils whilst colognes only contain 1 -2% oils.
Some perfumes contain just one scent such as verbena but most have a combination of a high note, the first scent that reaches you, middle notes, sometimes called heart notes, which is the personality of the perfume and finally the base note which lingers on.
It is important to remember that perfume reacts with each person’s body scent to create a unique aroma. That’s why the same cologne can smell so differently on different people. This is why you should try perfume on your own skin before buying otherwise you may be disappointed. A good rule of thumb is to never test more than three perfumes at a time.
Fragrance falls into six basic groups:
Florals: jasmine, lilac, gardenia, rose

The perfume can have top, heart, and base notes all from one category or mix the notes from different categories.

The precise formula of commercial perfumes are kept secret. Even if they were widely published, they would be dominated by such complex ingredients and odorants that they would be of little use in providing a guide to the general consumer in description of the experience of a scent. Nonetheless, connoisseurs of perfume can become extremely skillful at identifying components and origins of scents in the same manner as wine experts.
The most practical way to start describing a perfume is according to the elements of the fragrance notes of the scent or the family it belongs to, all of which affect the overall impression of a perfume from first application to the last lingering hint of scent.
Perfume compositions are an important part of many industries ranging from the luxury goods sectors, food services industries, to manufacturers of various household chemicals. The purpose of using perfume or fragrance compositions in these industries is to affect customers through their sense of smell and entice them into purchasing the perfume or perfumed product. As such there is significant interest in producing a perfume formulation that people will find aesthetically pleasing.
