Can Essential Balm Be Kept in a Car?

Keeping essential balm in a car poses certain risks. Here are some details about essential balm: 1. First point: Essential balm is mainly composed of menthol, camphor, methyl salicylate, eucalyptus oil, eugenol, chlorophyll, and fragrances. Although it does not contain alcohol and is not classified as a flammable item, these active ingredients can have a combustion-promoting effect. If a fire occurs in the car, essential balm may contribute to the combustion. 2. Second point: If essential balm is left for a long time in front of a car window exposed to sunlight during high temperatures, it may explode. In fact, items like car perfumes and lighters are also flammable. Especially during hot summer months, it is best not to keep such items in the car, as both the external and internal temperatures of the car can become very high, increasing the risk of explosion or fire.
I'm the type who likes to keep small items in the car, and menthol oil is indeed quite refreshing. But in summer, car temperatures can easily reach 60-70 degrees Celsius, causing plastic bottles to expand and deform—something that happens all too often. Once, the cap of my menthol oil popped open, and the liquid spilled all over the seat seams. The mix of mint and leather scent lingered for two months. Now, I store it deep inside the glove compartment, wrapped in aluminum foil for insulation. If you really need a pick-me-up, I’d recommend trying small-packaged wet wipes or simply sticking a cooling patch on the back of your neck—it’s much safer than risking chemical spills. Long drives can make you drowsy, and safety should always come first.
Having driven for over a decade, I've witnessed numerous troubles caused by items left in cars. The alcohol and camphor components in essential balm evaporate rapidly under high temperatures. Last year, a colleague's car experienced bottle explosion due to excessive internal pressure, with the liquid corroding plastic parts on the center console. This is especially risky when parked under direct sunlight, where dashboard temperatures can get hot enough to fry an egg. My personal practice is carrying a small amount of essential balm in a travel-sized bottle and taking it with me when leaving the car. Actually, there are many safer alternatives for staying alert, such as drinking iced mint tea or using cooling fragrance clips on AC vents, which work just as effectively.
