From highest concentration to least, the different forms of perfume are:
- Perfume, also called extract or extrait perfume, can include 15-40% perfume concentrates. This is the purest form of scented product and is the most expensive as a result.
- Eau de parfum contains about 7-15% perfume concentrates. This is the most popular and common form of perfume. It provides a long-lasting fragrance and generally doesn't cost as much as extract perfume.
- Eau de toilette has around 1-6% perfume concentrates. This makes for a light scent that doesn't linger as long as the more intense versions. It was originally intended to be a refreshing body splash to help people wake up in the morning.
- Eau de cologne is sometimes used interchangeably with the term eau de toilette. However, the concoction began as the name of a light, fresh fragrance mixed with citrus oils and was made popular by Napoleon. Some perfumers today have a version of this called eau fraiche.
