Parfum contains between 20-25% of oil concentration. Parfum have the highest fragrance concentration (more than 20% oil concentration), this means that it is likely to be noticeable and last all day. As a consequence, parfum will also demand the highest price. 

Eau de Parfum contains between 15-20% of oil concentration, this is the next highest fragrance concentration. Eau de parfums are made to last on the skin without giving people next to you a headache, or transferring onto someone else’s neck after a hug. These are the most common fragrance category. The scent will be prominent from morning to evening, and should still be detectable when you undress at night. 

Eau de Toilette contains between 8-12% of oil concentration. This is one of the most popular type of fragrances, with a concentration of between 8% to 12%, it is cheaper than the eau de parfum. 

Eau de Cologne/Fragrance Mist contains between 2-6% of oil concentration. With a much lower fragrance concentration about 2% to 6% and a high alcohol content, the eau the cologne is considerably cheaper than those above.

Eau Fraiche contains between 1-2% of oil concentration. This last fragrance is quite similar to the previous one, However, it has an even lower fragrance concentration of only 1% to 2%. The main difference is that eau fraiche/fragrance mist does not contain a high amount of alcohol. Eau fraiche/ fragrance mist is mostly water so this is also good for those with sensitive skin. 

On a final note, along with fragrance types it is important to know that there are also fragrance notes which determine the final scent.
