Will Perfume Be Affected if Left in a High-Temperature Car?
2 Answers
Perfume left in a high-temperature car can have significant effects. Since perfumes often contain alcohol and industrial fragrance ingredients, and alcohol is highly volatile, perfume is considered a flammable and explosive substance. When the temperature inside the car reaches a certain level, the alcohol in the perfume can evaporate, potentially causing the perfume bottle to burst and explode. Below are some precautions for driving in high temperatures: 1. Check if the air conditioning is low on refrigerant: The air conditioning is one of the most frequently used components in summer and is also prone to malfunction. It is recommended to check if your car's air conditioning is low on refrigerant before the peak of summer. Generally, insufficient refrigerant is one of the reasons for air conditioning failure. Next, check for any leaks. Most dryer tanks have a glass inspection window, and the flow of bubbles can give a preliminary indication of its condition. Finally, check if there is a lack of refrigeration oil. 2. Avoid prolonged driving when possible: In extreme heat, try to avoid long drives. Take breaks as needed during the trip. When parking, choose shaded and well-ventilated areas, and if conditions allow, open the engine hood for ventilation and cooling. 3. High-temperature road conditions can increase tire pressure: Due to the hot weather and high temperatures in summer, avoid carrying flammable or explosive items in the car and refrain from smoking inside to prevent fires. Before driving, regularly check for short circuits or leaks in the electrical system, and ensure plugs are secure. Inspect fuel line connections for leaks and the exhaust pipe for backfiring. If any issues are found, repair them immediately. Also, ensure the battery's vent holes remain unobstructed.
That day I drove out and forgot my newly purchased perfume on the dashboard. After a few hours of sun exposure, I found the bottle had deformed when I returned. A perfumer friend explained that the alcohol in perfume evaporates faster under high temperatures, increasing internal pressure and making leakage more likely, while the scent also becomes particularly pungent. The worst are those with metal caps—they get so hot you can burn yourself touching them. Now I either store perfume in the shaded glove compartment or simply don’t bring it in the car. If you really want a car fragrance, solid scent clips are much safer—at least they won’t leak sticky liquid all over the car.
