Leaving perfume in a hot car can cause it to degrade quickly, leading to changes in scent, discoloration, evaporation, and potential explosions. The original packaging of a perfume is designed to shield it from light and heat, and storing perfume in a cool, shaded area is ideal. However, some people choose to keep perfume in their car for convenience, especially if they attend social gatherings often or have housemates who are allergic to fragrance. While it may seem appealing to have perfume on hand for a quick refresh, the extreme temperatures in a car can negatively affect its quality.

What You'll Learn
Heat and sunlight can degrade perfume
Heat and sunlight can significantly impact the quality of perfume. Leaving perfume in a hot car can cause it to degrade and change its scent. This is because heat accelerates the degradation process, making the perfume expire faster. Sunlight exposure, in particular, can cause the breakdown of fragrance molecules due to UV rays.
The composition of the perfume, the type of bottle, and the duration of heat exposure all influence how quickly the fragrance spoils. Dark or opaque bottles offer extra protection against light, helping to preserve the fragrance for longer. Additionally, the original packaging of a perfume is designed to shield it from light and heat, so keeping it in its box can help maintain its integrity.
When exposed to high temperatures, the alcohol component in perfume is likely to evaporate, destroying the fragrance. This can also lead to an expansion of gas inside the bottle, which may cause it to explode. The heat can also cause the top notes of a perfume, which are the most volatile, to evaporate quickly, altering the overall balance of the scent.
To prevent perfume from spoiling, it is recommended to store it in a cool, dark place. A basement or an air-conditioned room can be ideal during the summer months. When travelling, it is best to store perfume in a cool, shaded area of your luggage, avoiding direct sunlight.
While it may be convenient to keep perfume in a car for quick touch-ups, the extreme temperatures can negatively affect its quality. It is advisable to store perfume properly, keep it tightly sealed, and avoid exposing it to heat to extend its shelf life.

The alcohol in perfume may evaporate or explode
Perfumes contain alcohol, which is used to dilute and “carry" the fragrance blend. This alcohol is different from consumable alcohol, and is legally declared undrinkable. It is completely safe to wear perfumes with alcohol, and it will not enter your bloodstream. In fact, most of the alcohol in a perfume will evaporate within a minute of spraying on the skin. The evaporation of alcohol helps the fragrance project better than pure perfume oil.
However, the alcohol in perfume can be flammable and needs to be kept away from heat or open flames. If exposed to high temperatures, the alcohol vapors can ignite and cause an explosion. This is why it is not recommended to leave perfume in a hot car, as it can accelerate the degradation process and cause potential evaporation or even an explosion.
The composition of the perfume, the type of bottle, and the duration of exposure to heat all play a role in how quickly the fragrance degrades. Exposure to sunlight, high temperatures, and humidity can affect the chemical stability of the perfume and accelerate the evaporation and oxidation processes.
To extend the shelf life of your perfume, it is important to store it properly, keep it tightly sealed, and avoid exposing it to extreme temperatures. The original packaging of a perfume is designed to protect it from light and heat, so keeping it in its box can help maintain its integrity. Additionally, dark or opaque bottles offer extra protection against light, helping to preserve the fragrance for a longer time.

Humidity can affect chemical stability
It is not advisable to leave perfume in a car, especially in hot weather. Exposure to high temperatures can cause the perfume to degrade, leading to changes in scent, discoloration, and potential evaporation. The heat can also cause the gas inside the bottle to expand, which may lead to an explosion.
Now, let's focus on the impact of humidity on chemical stability:
Humidity can indeed affect the chemical stability of perfume. High humidity can negatively impact the chemical processes in refineries and chemical plants, and this principle can be applied to understanding how humidity affects perfume. The presence of water vapor in the air, a key characteristic of high humidity, can influence the rate of evaporation and oxidation processes. This is because water vapor in the atmosphere contains "latent" energy, which plays a role in cooling the Earth's surface through transpiration or evaporation. In the context of perfume, this can impact the evaporation rate of the alcohol component, altering the chemical composition and stability of the fragrance.
Additionally, humidity can affect the ambient oxygen concentrations in the air. In dry air, oxygen levels are typically around 20.9%, while at 100% relative humidity, oxygen levels drop to approximately 20.4%. This change in oxygen concentration can influence the chemical processes and stability of the perfume, as oxygen is a crucial element in many chemical reactions.
The impact of humidity on chemical stability also extends beyond perfumes. For example, in baking, high humidity can accelerate the baking process or even cause burning, while low humidity slows it down. This is because high humidity increases the thermal conductivity of the air around the baked goods. Similarly, in the human body, high humidity can affect heat dissipation through perspiration and evaporation, leading to physical fatigue and heat-related health issues.
To minimize the impact of humidity on perfume, it is recommended to store it in its original packaging, in a cool, dark place, and away from direct sunlight. The original box and opaque bottles provide protection from light and heat, helping to maintain the integrity of the fragrance for a longer period. Proper storage can help extend the shelf life of perfumes, which is typically between three to five years.

Perfume should be stored in its original packaging
Storing perfume in a car is not recommended, as direct sunlight and high temperatures can cause the fragrance to degrade and evaporate. The perfume's alcohol component is also likely to evaporate, which can cause the bottle to explode.
The packaging also helps to keep the bottle upright and stable, preventing accidental spills or breakage. Additionally, the box can provide cushioning if the bottle is accidentally dropped, reducing the risk of shattering.
Another benefit of keeping the perfume in its original box is that it makes storage easier. The boxes can be stacked and stored in a cool, dry place, such as a bedroom drawer or cupboard, away from direct light and temperature fluctuations.
Proper storage is essential to ensure the lifespan and maximize the scent of the perfume. By keeping it in its original packaging and storing it in a suitable location, you can maintain the quality and longevity of your favourite fragrance.

Decanting perfume is a good option for on-the-go
Leaving perfume in a hot car can cause it to degrade quickly, leading to changes in scent, discoloration, and potential evaporation. Extreme temperatures can also cause the gas inside the bottle to expand, which may lead to an explosion.
To decant perfume effectively, you'll need the right tools. Here's a list of what you'll require:
- Perfume bottles: Choose glass or plastic containers with tight-fitting caps to prevent evaporation and leakage. Glass is preferable for larger decants as it helps preserve the perfume better. You can also source glass vials that block UV light.
- Funnel: A small funnel with a narrow spout, preferably metal or glass, will help you pour the perfume accurately without spilling. Plastic funnels can also be used but be sure to use them only for the same perfume or clean them thoroughly after each use.
- Pipettes or atomizers: These are useful for transferring the perfume from the original bottle to the smaller containers.
- Labels: Clearly label each decanted bottle with the name of the perfume, its brand, and any other relevant information. You can use a simple label maker or a sharpie pen, but be aware that the ink may disappear due to the alcohol and oils in the perfume.
By mastering the art of perfume decanting, you can create your own collection of travel-friendly fragrances that are exquisite and convenient for on-the-go use.
