Chemistry

How Chemistry Plays a Role in Fragrance:

Fragrance creation is a mix of art and chemistry. The volatility (or rate of evaporation) of each note depends on the molecular weight of the compounds. Top notes are small, lightweight molecules that evaporate quickly. Mid notes have medium-sized molecules that last longer, and base notes are made of heavier molecules that linger on the skin.

The balance of oils, alcohol, and fixatives (like glycerin or resins) in a perfume affects how these notes are released and how long they last. Alcohol helps disperse the fragrance by evaporating quickly, while fixatives slow the evaporation of the oils, allowing the scent to evolve gradually.

How to Choose a Fragrance Based on Notes:

When selecting a fragrance, it’s helpful to understand how it will change over time. A scent might start with a bright, citrusy top note but evolve into a rich floral heart and finish with warm, woody base notes. When you first spray a fragrance, you're smelling primarily the top notes, but give it time to let the heart and base notes reveal themselves.
