Can Solid Car Fresheners Catch Fire in the Car?

Solid car fresheners may catch fire in the car. Here is some information about solid car fresheners: 1. Material: The main components of car fresheners are various fragrances and beeswax. Due to the beeswax, car fresheners remain solid at room temperature. 2. Function: Good-quality fresheners use purely natural plant-extracted fragrances instead of synthetic ones, providing a relaxing and pleasant scent. 3. Harm to human health: The market offers a wide variety of car fresheners with varying brands, quality, and prices, some of which may even be unregulated products. Placing these low-quality solid fresheners in the car for a long time can cause harm to organs such as the nerves, throat, lungs, and liver, especially irritating the respiratory system to varying degrees, potentially leading to symptoms like dizziness, coughing, nausea, and vomiting.

Solid car air fresheners can indeed catch fire, especially during hot summer months. I remember one time when I parked my car in direct sunlight, and the temperature inside soared to over 50 degrees Celsius. The air freshener melted and started emitting smoke, nearly causing a fire. The reason is simple: solid air fresheners contain volatile fragrances and solvents that evaporate into gas under high temperatures. If exposed to a heat source or flame, they can easily ignite. I recommend choosing products with low-volatility labels and storing them in cool places like the glove compartment. During hot weather, use sunshades or car covers to reduce interior heat. Always park in the shade and avoid placing air fresheners near heaters or the dashboard. For safety, regularly inspect and replace them to ensure peace of mind while driving.

I've placed solid air fresheners in my car several times, and experience has taught me not to take it lightly. In winter, there's generally no issue, but during summer when the car is exposed to extreme heat, the freshener can soften, deform, or even melt, increasing the risk of fire. My approach is to only purchase car-specific air fresheners, as they have better heat resistance. On hot days, I avoid long-term storage—I only place a small box in the car during my commute and remove it when parking, storing it in my bag instead. This helps control temperature fluctuations and prevents accelerated evaporation. I also recognize the importance of ventilation inside the car; on hot days, I crack the windows slightly to let air circulate and prevent the fragrance from becoming too concentrated. From a health perspective, while high-temperature combustion is rare, taking preventive measures can save a lot of trouble.

The flammability of solid fragrance balms in cars is influenced by temperature. In the enclosed environment of a car, temperatures rise rapidly under sunlight, causing chemical substances in the balm, such as alcohol or essential oils, to evaporate into a gaseous state. When the concentration is high, they can easily ignite. For example, lemon oil has a low flash point, posing a higher risk on hot days. I usually choose balms with low-volatility ingredients and avoid storing them in direct sunlight. I remind myself to use more sun protection measures when parking in summer and to seal the balm properly after use. This theoretically reduces fire hazards while maintaining clean air inside the car.
