Perfume


Perfume (English: /ˈpɝː.fjuːm/, French parfum pronounced: [paʁ.fœ̃]) is a mixture of fragrant essential oils and/or aroma compoundsfixatives, andsolvents used to give the human body, animals, objects, and living spaces a pleasant scent.[1] The odoriferous compounds that make up a perfume can be manufactured synthetically or extracted from plant or animal sources.
Perfumes have been known to exist in some of the earliest human civilizations either through ancient texts or from archaeological digs. Modern perfumery began in the late 19th century with the commercial synthesis of aroma compounds such as vanillin or coumarin, which allowed for the composition of perfumes with smells previously unattainable solely from natural aromatics alone.


Concentration

Perfume types reflect the concentration of aromatic compounds in a solvent, which in fine fragrance is typically ethanol or a mix of water and ethanol. Various sources differ considerably in the definitions of perfume types. The intensity and longevity of a perfume is based on the concentration, intensity and longevity of the aromatic compounds (natural essential oils / perfume oils) used: As the percentage of aromatic compounds increases, so does the intensity and longevity of the scent created. Specific terms are used to describe a fragrance's approximate concentration by percent/volume of perfume oil, which are typically vague or imprecise. A list of common terms is as follows:
  • Perfume extract, or simply perfume (Extrait): 15-40% (IFRA: typical 20%) aromatic compounds
  • Esprit de Parfum (ESdP): 15-30% aromatic compounds, a seldom used strength concentration in between EdP and perfume
  • Eau de Parfum (EdP), Parfum de Toilette (PdT): 10-20% (typical ~15%) aromatic compounds, sometimes listed as "eau de perfume" or "millésime"
  • Eau de Toilette (EdT): 5-15% (typical ~10%) aromatic compounds
  • Eau de Cologne (EdC): Chypre citrus type perfumes with 3-8% (typical ~5%) aromatic compounds
  • Perfume mist: 3-8% aromatic compounds (typical non-alcohol solvent)
  • Splash and After shave: 1-3% aromatic compounds
