SUMMARY

This discussion explores the longevity of perfume scents, emphasizing that perfumes are complex mixtures of various substances designed to last longer than simple liquids. The evaporation rate of individual compounds plays a crucial role in scent persistence, as some components evaporate slowly, allowing the fragrance to linger. Additionally, the interaction of perfume with skin can create a chemical reservoir that further enhances scent retention. Understanding these factors is essential for both consumers and creators of fragrances.

PREREQUISITES
  • Basic knowledge of chemistry, particularly regarding evaporation rates.
  • Understanding of perfume composition and the role of fixatives.
  • Familiarity with the concept of chemical reservoirs in skin absorption.
  • Awareness of the different types of fragrance notes (top, middle, base).
NEXT STEPS
  • Research the role of fixatives in perfumery and their impact on scent longevity.
  • Learn about the evaporation rates of various fragrance compounds.
  • Explore the concept of chemical reservoirs and their effects on fragrance retention.
  • Investigate the classification of fragrance notes and their contributions to overall scent profiles.
USEFUL FOR

Perfume enthusiasts, fragrance creators, chemists, and anyone interested in understanding the science behind scent longevity and composition.

When we put on perfume for a small amount, the smell could last for a few hours, or at least, an hour, I am wondering why it can last this long? If perfume is
in liquid form, we shouldn't be able to detect it because liquid won't go into our nose. If it's in gaseous form, it should be quickly brought away by the air, the gas shouldn't be able to stay around the person as he/she walks. Or is it a kind of liquid that slowly evaporates?

Also keep in mind that perfume is not a single compound.
They are mixes of lots of different substances put together by the perfume making person, with the goal of making something that will last a while.
A smelly compound might evaporate slowly, until it is gone, based on its rate of evaporation along.
When mixed with something else, it could heave a greater tendency to stay in that solution then go into the air.
It could also soak into the skin, producing a chemical reservoir in the skin that might be less likely to get airborne.
