The art and science of creating perfumes is called perfumery. It involves the use of a variety of fragrance ingredients, which are combined to create a desired scent. Perfumery is both an art and a science, as it requires a creative flair to develop new fragrance compositions, as well as a knowledge of the chemistry behind the interaction of different fragrance materials.

There are three main categories of fragrance ingredients: top notes, middle notes, and base notes. Top notes are the lightest and most volatile molecules in the perfume, which means they are the first to evaporate when applied to the skin. They provide an initial impression of the scent and typically last for 5-10 minutes. Middle notes emerge after the top notes have dissipated and form the heart of the perfume composition. They usually last for 30 minutes to 1 hour. Base notes are heavier molecules that anchor the other two types of notes and give longevity to a perfume’s scent (i.e., they make it last longer on your skin).

Perfume compositions can be either linear or complex. Linear fragrances have all their components blended together so that no one note stands out more than any other—think of it like wearing all one color from head-to-toe. In contrast, complex fragrances have distinct layers that you can smell separately as they dry down on your skin; for example, you might be able to smell each individual note in Chanel No5 .
