EDP Parfum

By admin  

When shopping online, or even the old fashioned way in high street shops there is a bewildering array of perfumes and aftershaves. Looking across the ranges available from Armani to Versace or Banan Republic to Yves Saint Laurent there is a huge range of products to choose from. However many people get confused over the difference between Eau de Perfum (EdP), Eau de Toilette (EdT) and Eau de Cologne (EdC). Because of the difference in the products ingredients the price between these can be considerable.

Most manufacturers of designer label perfumes and aftershaves provide various versions of each product. The difference between these is the concentration of the aromatic compounds that are contained within the finished scent.

The most concentrated of these is called ‘Perfume Extract’ (Extrait) where the aromatic compounds can be between 15% and 40%. That said you will rarely find this as it can iritate the skin it is so strong.

Eau de Parfum (EdP) is the next most concentrated and is also sometime known as  Parfum de Toilette (PdT). The aromatic compounds for this fragrence are typically 15% but can range from 10% to 20%. It is sometimes listed as “eau de perfume” or “millésime”.

Eau de Toilette (EdT) is the next strongest with a typical concentration of about 10%, but again this can range from between 5% to 15% of the aromatic compounds that give it its distinctive smell.

With a typical concentration of 5% (but again varying, this time between 3 and 8%) is Eau de Cologne (EdC). In this category you will find Chypre citrus type perfumes.

Finally, Splash and After shaves contain about 1% to 3% of the aromatic compounds.

Perfume oil has to be diluted with a solvent because undiluted oils contain high concentrations of chemical components  that will likely result in allergic reactions and possibly injury when applied directly to skin or clothing. Also the pure forms of the scents tend to be very expensive, diluting with a cheap solvent makes the product cheaper. Also somewhat suprisingly the high concentration of aromatic compounds in pure perfumes make them rather unpleasant and most people would be put off by them. By far the most common solvents for the dilution of perfume oil  are alcohol and water. The alcohol normally used is ethanol. However other substances can be used to dilute perfume oil with fractionated coconut oil, or liquid waxes such as jojoba oil being frequently used.

The intensity and longevity of a perfume is based on the concentration, intensity and longevity of each of the aromatic compounds (natural essential oils / perfume oils) used. The ingredients in a perfume evaporate at different rates. This is why a freshly applied perfume or aftershave smells different a couple of hours later.  As the proportion of aromatic compounds increases in the product, so does the intensity and longevity of the scent created. Different perfumeries or perfume houses assign differing amounts of oils to each of their perfumes which they produce. Consequently, 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. So be warned, an EdT from one house may be stronger than an EdP from another!

Men’s fragrances, which normally referes to aftershaves, are rarely as EdP or perfume extracts. Also  women’s fragrances are rarely sold in EdC concentrations. Although this gender specific naming trend is most common for attributing fragrance proportions, it does not directly have much to do with whether a fragrance was intended for men or women.

So when you are shopping online for your favorite scent, be it a perfume or an aftershave by Jean Paul Gaultier or Givenchy, check to see what concentration you normally buy and then compare the prices for the same concentration of the product.

Extrascents is an example of a UK based online perfume store retailing cheap perfume for women and for men a range of cheap aftershave.
