Is Car Cooling Spray Harmful to the Human Body?

[DelilahRose]

Car cooling spray is not harmful to the human body. Cooling spray is a specialized product designed for vehicles, which can rapidly reduce the temperature inside the car within minutes by simply spraying it on the car's surface or any interior decorations. The following is an introduction to car cooling spray: 1. Definition and Composition: Car cooling spray is a formulation that can quickly lower the temperature inside the car, primarily composed of dry ice, softened water, and a small amount of fragrance. 2. Features: Rapid cooling, non-toxic, non-corrosive, pollution-free, environmentally friendly, with no side effects on the human body, and it is also portable and easy to use.

I've specifically studied the ingredient list of this stuff. Many car cooling sprays contain flammable compressed gases like dimethyl ether and propane, which can cause a stinging sensation when sprayed on the skin, especially for those with sensitive skin. Last time my friend used it, his entire arm broke out in red rashes, and the doctor said it was due to chemical solvent irritation. What's worse is that spraying large amounts in enclosed spaces can cause dizziness and nausea from inhaling those volatile organic compounds, and long-term exposure may even damage respiratory mucosa. When choosing products, check if they have an MSDS (Material Safety Data Sheet). Never buy unregulated products just to save money. It's recommended to wear gloves and ensure proper ventilation when using them.

I've disassembled over a dozen mainstream cooling sprays and found that 80% of the cans are labeled 'Keep away from environments above 60°C'. Last summer, a repair shop encountered a case where a can exploded after being exposed to direct sunlight—shrapnel embedded directly into the leather seats. Be especially wary of certain off-brand products that add industrial fragrances to mask the solvent smell; what smells like mint may actually contain chlorofluorocarbons. The safest method of use is to spray quickly from 30 cm away and avoid sitting on the surface immediately afterward. Parents should be particularly cautious, as these cans resemble children's sunscreen sprays—inhaling even a small amount can potentially trigger laryngospasm.

Component testing reveals that most sprays can achieve an instant low temperature of -20°C. When sprayed onto a steering wheel, the temperature difference exceeds 70°C. While leather aging and cracking are minor concerns, the sudden contact of palms with extreme cold may trigger vascular spasms. I've even seen someone spray it directly into an air conditioning vent, resulting in frozen compressor condensate that blocked the airflow. Experiments prove that cooling towels are over three times safer than sprays. Soaked in water and wrung out, they provide physical cooling without damaging interiors or posing inhalation risks, making them particularly suitable for pregnant women and those with asthma.

According to chemical storage regulations, these pressurized cans must be stored upright in a cool place. However, many people casually leave them in door storage compartments. In summer, car interior temperatures can easily exceed 80°C, causing the internal pressure to triple. Last month's fire drill demonstrated that the explosion of inferior aluminum cans in a sun-exposed car cabin can be as powerful as a grenade. The truly safe practice is to carry them personally and remove them when exiting the vehicle. If the can appears swollen or the valve shows frost formation, it should be treated as hazardous material. As a side note, liquid-type sprays actually provide the best cooling effect—they evaporate slowly but offer long-lasting performance.
