The Aging of Perfumes: Changing Colors and Odors
Share
Perfumes, like fine wines, evolve over time. However, unlike wines, this evolution is not always desired. Here's a look at how perfumes change color and smell as they age, tips for storing them properly, and when you should be concerned about these changes.
Change of Colors and Odors
Over time, it is common for perfumes to change color and smell. These changes can be due to several factors:
- Oxidation : Exposure to air can cause fragrance components to oxidize, changing its color and scent. For example, citrus notes may become duller and floral notes may lose their freshness.
- Light : Exposure to light, especially direct sunlight, can degrade fragrance molecules, causing color changes and altered olfactory notes.
- Temperature : Temperature variations can also affect the stability of fragrances. Excessive heat can accelerate the degradation process, while temperatures that are too low can alter the chemical composition.
- Humidity : Humidity can also play a role in fragrance degradation. A humid environment can promote mold growth and alter the scent components. Therefore, it is important to store fragrances in a dry place to avoid these problems.
How to Store Perfumes Properly
To preserve the quality of your perfumes and slow down their aging, here are some storage tips:
- Storage Away from Light : Store your perfumes in a dark place, away from direct sunlight. Cupboards or drawers are ideal places.
- Constant Temperature and Dry : Keep your perfumes in a cool, dry place at a constant temperature. Avoid bathrooms where temperature and humidity fluctuations are frequent.
- Tightly Sealed Cap : Make sure your bottle cap is tightly sealed to minimize exposure to air and reduce the risk of oxidation.
- Opaque Bottles : If possible, opt for opaque or dark bottles that better protect the contents from light. Otherwise, remember to keep the original packaging to store your perfume in.
Should I be concerned about a change in color and/or odor?
A slight change in color or scent isn't necessarily a sign that your perfume has become unusable. However, there are a few signs to look out for:
- Rancid or Sour Odor : If your perfume develops a rancid or sour odor, this may indicate that the components have degraded significantly.
- Drastic Color Change : A very pronounced color change can also be a sign of advanced degradation.
- Loss of Sillage : If your perfume no longer projects as well or lasts as long as it used to, it may indicate that the top notes have evaporated or degraded.
Vanilla Based Perfumes
It is important to note that perfumes containing vanilla may darken over time. This color change is due to the natural oxidation of vanillin and does not usually affect the quality or scent of the perfume. So if your vanilla-based perfume darkens, there is no need to worry.
The shelf life of well-preserved perfumes
Perfumes, thanks to their high concentration of essential oils, can be stored for between 5 and 20 years. The lightest notes degrade first, between 3 and 10 years, then the heavier notes such as vanilla or oud wood for example, can take between 10 and 20 years to degrade. The higher the concentration, the longer the perfume will last. Eau de Toilette and Eau de Cologne, these lighter formulas, containing less essential oils, are more sensitive to oxidation and are generally stored for between 2 and 5 years.
To maximize the life of your perfumes, it is essential to keep them away from light, heat, humidity and air, as mentioned above. By following these tips, you will be able to enjoy your favorite fragrances for longer.
In conclusion, although perfumes can change over time, proper storage can extend their life and preserve their quality. If you notice significant changes, it may be time to replace your bottle. By following these tips, you will be able to enjoy your favorite fragrances for longer.
