The Curious Case of the New Car Smell

The enticing 'new car smell' is a phenomenon that many of us can't resist. We perceive it as a sign of freshness, but is it really that innocent? This article explores the science behind this popular scent, its composition, and its potential health implications.

What is Giving off the Smell?

The smell of a new car isn't just due to plasticizers like dioctyl phthalate (DOP) that are used to make plastic components. When your car is exposed to heat, especially on a sunny day with the windows closed, it can release a complex mixture of volatile organic compounds (VOCs), contributing to both the odor and possible health concerns.

The Role of PVC and Plasticizers

During production, PVC (polyvinyl chloride) granules are suspended and polymerized. Raw PVC is heated, blended with chemical plasticizers, and colors to meet customer specifications, forming pellets that are packaged and shipped. With leather interiors, there would be less need for plasticizers, leading to a more natural and pleasant aroma.

Volatile Organic Compounds (VOCs)

The 'new car smell' is largely caused by a cocktail of VOCs released from rubber, plastics, and adhesives. Some common compounds include toluene, benzenes, alkanes, acetones, aldehydes, and other hydrocarbons. If you have leather seats, you may also find musk, civetone, or their chemical analogs in the air.

A Hidden Health Hazard

Despite the pleasant odor, the chemical cocktail present in new cars is not without risks. Toluene and benzene, found in car petrol and paraffin candles, are known to be carcinogenic. We have become accustomed to this smell, associating it with newness and freshness, but it's essential to recognize the potential health hazards.

Health Concerns and Advice

Given the presence of harmful chemicals, it's advisable to open your car windows to allow the VOCs to dissipate. This is especially important in the case of new carpets, which may also release these chemicals if made from rubber or plastic materials. Regular exposure can adversely affect your health, and it's crucial to prioritize your well-being over the allure of a new scent.

Is There Something You Can Do?

The health implications of VOCs in new cars are serious enough to warrant caution. If you are concerned about your health, consider purchasing a slightly used car instead of a brand-new one. This approach not only reduces the impact on your health but also makes financial sense.

Common Sense Conspiracy Theory

In my opinion, the dangers of VOCs in new cars are significant and should not be overlooked. A conspiracy theorist might suggest that Steve Jobs, known for his love of new Mercedes, could have been exposed to harmful chemicals that contributed to his untimely health diagnosis. The plastic coating on a yacht's hull takes over a year to cure, remaining fresh and potentially harmful. Similarly, the new car smell is an indicator of the same harmful chemicals in plastic components.

Addressing the Global Issue

While individual actions can make a significant difference, systemic changes are also needed. If manufacturers were required to wait at least nine months after production before selling new cars, it would significantly reduce the immediate exposure to these harmful chemicals. Unfortunately, such regulations are unlikely to be implemented.

Your Best Bet: Buy a Slightly Used Car

Ultimately, your health and well-being are the most important factors to consider. If you encounter a new car that smells incredibly strong, it might be wise to reconsider your purchase. By opting for a slightly used car, you can enjoy the benefits of a newer vehicle without the immediate exposure to harmful chemicals.

Remember, staying informed and taking steps to protect yourself is the best course of action. Trust your intuition and make choices that prioritize your health and safety.

Conclusion

While the new car smell may be pleasant, it's essential to recognize the potential health risks it represents. By understanding the composition of these chemicals and taking appropriate precautions, you can minimize your exposure and make informed decisions about your purchases.
