What Are 'Notes' In Fragrance Oils?

A fragrance is divided into 3 distinct parts: top note, middle note, and base note. Each of these usually has an assortment of ingredients.

  • Top Note – This is the initial immediate smell you notice when you sniff a fragrance oil. This is known as the initial fragrance ‘burst.’
  • Middle Note – This is considered to be the heart of the fragrance and becomes more prevalent once the top note dissipates.
  • Bottom Note – The base notes are long lasting and provide depth to the fragrance. Also referred to as the 'dry down.'
