Most perfumes are complex combinations of natural materials, such as essential oils from plants, and synthetic products that increase the lasting power and heighten the smell. Alcohol is used as a liquid base for perfume, and the ratio of alcohol to scented perfume concentrates determines what the final concoction is labeled.

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.

While these are the main classes of perfume, other products are frequently scented with perfume concentrates too. Lotions, creams, powders, body splashes, aftershaves, soaps, and other cosmetic products may contain variable (though usually small) amounts of fragrance.

Now that you have your scents straight, we're sure you'll smell like a rose all day!
