Perfume
|
Perfume is a mixture of fragrant essential oils and aroma compounds, fixatives, and solvents used to give the human body, objects, and living spaces a pleasant smell.

The precise formulas of commercial perfumes are kept secret. Even if they were widely published, they would be dominated by such complex chemical procedures and ingredients that they would be of little use in providing a useful description of the experience of a scent. Nonetheless, connoisseurs of perfume can become extremely skillful at identifying components and origins of scents in the same manner as wine experts. |

Perfume oil is necessarily diluted with a solvent because undiluted oils (natural or synthetic) contain high concentrations of volatile components that will likely result in allergic reactions and possibly injury when applied directly to skin or clothing. By far the most common solvent for perfume oil dilution is ethanol or a mixture of ethanol and water. Perfume oil can also be diluted by means of neutral-smelling lipids such as jojoba, fractionated coconut oil or wax. The concentration by percent/volume of perfume oil is as follows: |
|
Perfume extract
|
20%-40% aromatic compounds
|
6 – 8 hours
|
|
Eau de parfume
or EDP |
10-30% aromatic compounds
|
5 – 7 hours
|
|
Eau de toilette
or EDT |
5-20% aromatic compounds
|
4 – 6 hours
|
|
Eau de Cologne or EDC / Aftershave
|
2-5% aromatic compounds
|
2 – 3 hours
|
| As the percentage of aromatic compounds increases, so does the intensity and longevity of the scent created. Different perfumeries or perfume houses assign different amounts of oils to each of their perfumes. Therefore, although the oil concentration of a perfume in eau de parfum (EDP) dilution will necessarily be higher than the same perfume in eau de toilette (EDT) from within the same range, the actual amounts can vary between perfume houses. An EDT from one house may be stronger than an EDP from another. |
| The price of a fragrance product will depend on its strength (% of perfume oil) as well as the bottle size. For example, a 30 ml Eau de Parfum bottle will usually cost more than a 30 ml Eau de Toilette as it is stronger. The more alcohol a product contains, the quicker its scent will evaporate. Aftershave has the highest alcohol content. Although an Eau de Toilette is cheaper, it is not necessarily more economical, as it will not last as long. EDT is the most popular and affordable concentration available. |
