What makes a perfume different from the other is the amount of aromatic compound concentrated or mixed in the solvent used in it. When buying a perfume, surely you have seen the labels eau de parfum, eau de toilette or eau de cologne. So what are the differences?
If it only says parfum, extrait perfume, or what is also called as perfume extract, this is the most concentrated form. Typically this has 15% to 40% concentration of the perfume essence. This mix has the least alcohol or water content. Parfum is applied by dabbing, due to its high concentration of perfume.
Eau de Parfum (EDP)
The concentration of a eau de parfum ranges from 10% to 20% (usually 15%). This means that EDP is more lighter, subtler and less more expensive than the extract perfume, while still having the sophisticated quality of a fine fragrance. The scent of this type of concentration lasts around three to five hours from the time of application.
Eau de Toilette (EDT)
The concentration of a eau de toilette is lower than that of eau de parfum. Its concentration is only within the range of 5% to 15%. It is less expensive than a eau de parfum and lasts for around two to four hours. Historically, the eau de toilette was known as toilet water. This is because it was originally formulated to be splashed all over the body to freshen and instantly wake people up in the morning.
Eau de Cologne (EDC)
This is the lowest concentration of them all at only 3% to 5% concentration. This is also the cheapest form. The scent lasts only for around two hours. Therefore, its application must be properly timed.
Eau fraiche, which literally means “fresh water,” is the most diluted type of fragrance available. It is much lighter than cologne, having only about one to three percent concentration of aromatic compound. From the name itself, eau fraiche has less alcohol content than eau de cologne. But in most cases, it is free of any alcohol. The base of solution of eau fraiche is about 95-97% water. This makes it the cheapest fragrance you can find on the store shelves. It is great to use everyday, and it makes a good substitute to cologne since it has lesser alcohol, which can dry the skin.
