PERFUME 101 – Concentration
The concentration of a fragrance refers to the concentration of aromatic compounds (pure perfume oils) in the solvent; in fine fragrances this it is typically ethanol or a mix of water and ethanol, as denoted on the list of ingredients/allergens on the box. For the most past this also determines the longevity (how long) the fragrance/perfume will last… Although general guidelines are presented about the ratio of aromatic compound percentage/concentrations, different perfume houses (companies) assign and adhere to different amounts of essences/oils to each of their perfumes. However the chart below is basically a rule in which the majority of Fragrances companies are following these days, details below:
Perfume Extract (Extrait): The highest level of concentration, typically sold only in the top-of-the-line fragrance families. Concentration levels are between 16% and 40% at the highest point, with 20% being the typical level of concentration.
Eau de Parfum : The next highest level of fragrance and perfume concentration. At this level, fragrance concentration is between 15% and 20% with 15% being typical. This level is also sometimes called Eau De Perfume or Millesime. For example, the house of CREED releases almost all of its scents in the Millesime strength/concentration. This is the strength level preferred by most upper class and rich households. The best brands typically release their fragrances at this concentration level.
Eau de Toilette: This is the strength of most fragrances you will find at department stores frequented by the middle class (think J.C. Penney, Macy’s, etc.). A typical Eau de Toilette may cost between $65 to $95, making it affordable, therefore more attainable.
Eau de Cologne: Typically, these are citrus type scents that work well in low concentrations because they have no base notes. An Eau de Cologne has somewhere between 2% and 5% fragrance oils, with 5% being common.
Splash and After Shave: Products sold as after shaves or splashes have very little fragrance and it will quickly dissipate because the concentration levels of aromatic compounds stand at only 1% to 3%.
