Perfume

Perfume is a fragrant liquid applied to the body, clothing, or living spaces to emit a pleasant scent. It typically consists of a mixture of fragrant oils (derived from plants or made synthetically), ethanol to carry the fragrance, and a small amount of water.

Perfume is one of the most widely traded products of the cosmetics industry. It is used at celebrations, in daily life, and in religious contexts. Arab countries and Somalia are known for alcohol-free fragrant oils, such as oud and small bottles of perfume sold in shops.

Chemical composition

Every perfume has three layers of scent. The top notes are the first scent detected and fade quickly; these are usually citrus or spice. The heart notes come next and are typically floral or spice. The base notes last the longest and consist of heavy substances such as wood, oud, or musk.

Types and strength

Perfumes are classified by the percentage of fragrant oil they contain. Extrait de parfum has the highest concentration, followed by eau de parfum, eau de toilette, and eau de cologne, which is the lightest. The higher the oil content, the longer the scent lasts and the higher the price.

Production methods

Fragrant oils are extracted from plants using distillation, expression for citrus oils, or solvent extraction for delicate flowers such as jasmine. Since the late nineteenth century, synthetic chemicals have become essential to modern perfumery because they are stable and produce consistent scents.

History

The use of fragrant substances dates to ancient Egypt, Mesopotamia, and India, where incense and unguents were burned at religious ceremonies. The word 'perfume' derives from the Latin per fumum, meaning 'smoke passing through'. Islamic scholars, particularly al-Kindi and Ibn Sina, advanced the science of distillation. In later centuries, France—particularly the city of Grasse—became the center of Europe's perfume industry.
