Perfumes are a type of fragrance that can be made up of a variety of different components, including AROMAS, censes, attars, ESSENCES, ODORS, SCENTS, SPRAYS, and roseoils. AROMAS, censes, attars, and ESSENCES are all derived from natural sources, such as flowers, herbs, and spices, while ODORS, SCENTS, SPRAYS, and roseoils are synthetic fragrances created in a laboratory. Perfumes are used to enhance the smell of a person or an object, and can be used for a variety of purposes, such as to create a pleasant atmosphere or to mask unpleasant ODORS.
