Compound perfume is a type of fragrance made by combining multiple ingredients, such as essential oils, absolutes, and aroma compounds. The most common components of compound perfume are esters, which are organic compounds derived from the reaction of an acid and an alcohol; attars, which are fragrant oils derived from botanical sources; and essences, which are concentrated aromatic oils extracted from plants. Together, these components create a unique scent that can be used in perfumes, colognes, and other fragrances.
