What is the difference between Perfume, Eau de Parfum and Eau de Toilette?

Perfume

This is the extract of a fragrance and represents the scent in its purest form. This often creates a smooth and round texture, which is hard to achieve with the dilution represented in the other concentrations of fragrance.

Eau de Parfum

Eau de Parfum or EDP is one of the most popular forms of fragrance. Eau de Parfum contains between seven to fourteen per cent of essential oils and is the second strongest and longest lasting means of wearing a fine fragrance.

Eau de Toilette

Eau de Toilette or EDT is fast becoming the most common means of wearing a fragrance. EDT's are not as highly concentrated in essential oils as an EDP or Perfume would be and contain one to three per cent of fragrance oils. This impacts the ability of the fragrance to last and around eighty percent of the oils in an EDT fragrance will evaporate within three hours of application.
