Fragrances are chemical compounds designed to evaporate and linger in the air, creating a pleasant aroma. They are typically sprayed into the air as a fine mist of fragrance or released as droplets that transition into vapour. However, concerns have been raised about the adverse effects of fragrances on the environment and human health. Some evidence suggests that fragrances contribute to indoor air pollution and may pose health risks, particularly with long-term exposure. In addition, fragrances are susceptible to changes in air pressure, which can affect their composition and scent. While the impact of fragrances on the environment and human health is still being studied, it is clear that they have the potential to cause harm and require careful consideration and handling.

What You'll Learn
Air pressure and radiation may alter perfume
Let's start by discussing air pressure. When travelling with perfume, particularly on flights, changes in air pressure can cause leakage. This is because the pressure inside the bottle increases, which can lead to potential leaks or, in extreme cases, cause the bottle to crack or the cap to loosen. However, the impact of air pressure on the fragrance itself is less clear. Some people have reported that their perfume smelled differently after flying, with an increased alcohol scent.
Now, let's turn to the potential effects of radiation on perfume. The available information on this topic is limited, and it is challenging to establish definitive cause-and-effect relationships due to the ubiquitous presence of radiation in our environment. However, it is important to distinguish between radiation itself and contamination with radioactive materials (fallout). The latter poses a more significant concern, especially in the event of a nuclear disaster or proximity to radioactive sources. Sun radiation, for example, has been suggested to affect DNA but may have less impact on inorganic materials.
The impact of radiation on perfumes may also depend on their ingredients. Perfumes containing natural materials such as oak moss, sandalwood, or ambergris might be more susceptible to radiation-induced changes since these substances originate from living organisms. Additionally, the presence of alcohol in perfumes could be a factor, as alcohol is sensitive to heat and radiation can affect its chemical structure.
While the direct impact of radiation on perfumes may be minimal, it is worth noting that regulatory practices regarding radioactive content in consumer products vary across countries. Historically, radioactive substances like radium were added to cosmetics and healthcare products, including perfumes, with unproven health benefits. Today, some commercially available products still incorporate radioactive materials, and prolonged use of such products may contribute to cancer risks. Therefore, proper regulatory inspections and certifications are crucial to ensure consumer safety.
In summary, while air pressure may primarily affect the physical state of perfumes (e.g., leakage or evaporation), radiation's influence is more complex and dependent on various factors. The potential risks of radiation exposure lie more in the possibility of contamination with radioactive materials and the cumulative effects of daily exposure to radioactive consumer products.

Air fresheners can be toxic
Air fresheners are commonly used to mask unpleasant odours. While many of these products are designed to simply add fragrance to the air, others use disinfectants to remove odours. However, some evidence suggests that air fresheners increase indoor air pollution and pose a health risk, especially with long-term exposure.
Air fresheners release volatile organic compounds (VOCs) into the air. VOCs are types of chemicals that turn into vapour or gas at room temperature. Health problems are thought to occur as a result of the chemicals in the air fresheners and from their secondary pollutants. Secondary pollutants are formed when a product's chemicals combine with the ozone already in the air.
Some air fresheners contain ethanol, which is also found in alcoholic beverages. Others contain formaldehyde, acetaldehyde, benzene, toluene, and alpha-pinene, which is used in pine-scented fresheners. Phthalates are another common ingredient in air fresheners, which are chemicals that embed a fragrance in plastic or wax.
Air fresheners can cause skin irritation and redness, and fragrances are known to cause allergic-type skin reactions. Small amounts of air freshener in the eye can cause redness and irritation, and a small amount ingested can cause toxicity ranging from minor irritation of the mouth to life-threatening effects.
There is also evidence that long-term use of air fresheners can affect heart function, especially in individuals with lung disease. Air fresheners have also been linked to adverse effects on reproductive health, as they can impact a person's balance of hormones. Additionally, there is growing evidence that phthalates, aldehydes, and 1,4-dichlorobenzene, a common deodorizer, can cause cancer.
While air fresheners can have toxic effects, the degree of risk depends on the formulation and the amount of exposure. Inhaling small amounts of most air fresheners is usually not dangerous, but ingesting gel-type evaporative beads or reed diffuser solutions can cause serious health issues.

Air fresheners can cause indoor air pollution
Air fresheners are commonly used to mask or remove unpleasant odours. However, they contain a variety of chemical and biological components that can negatively impact indoor air quality and pose health risks, especially with long-term exposure.
Air fresheners emit over 100 chemicals, including volatile organic compounds (VOCs) such as formaldehyde, acetaldehyde, benzene, toluene, ethylbenzene, and xylenes. These VOCs are often odourless and can irritate the eyes, nose, and throat, causing headaches, nausea, and respiratory issues. They can also react with naturally occurring compounds in the air, such as ozone, to form secondary pollutants, further worsening indoor air quality.
The toxic effects of air fresheners vary depending on their formulation. While inhaling small amounts is usually not harmful, swallowing certain types, such as gel-based or reed diffuser solutions, can have serious consequences. Additionally, some air fresheners contain disinfectants like ethanol, which are intended to kill bacteria or mould but may contribute to indoor air pollution. High-tech versions that are heat-activated or automatically spray throughout the day can also pose fire hazards if ignited by a nearby flame.
The Environmental Working Group has assessed that over 75% of air fresheners contain either "likely" or "potentially significant" hazards to health or the environment due to exposure to their ingredients. These hazards include adverse health effects such as migraine headaches, asthma attacks, breathing difficulties, dermatitis, and neurological problems, especially for sensitive individuals.
It is important to note that even homemade or "natural" air fresheners made with essential oils may not be free of potentially harmful chemicals. These oils contain highly concentrated combinations of naturally-derived chemicals, and their safety has not been comprehensively tested.
Therefore, while air fresheners may improve odours, it is important to be aware of their potential to cause indoor air pollution and associated health risks.

Air fresheners can be flammable
While air fresheners are commonly used to mask unpleasant odours, some of them can be flammable and pose health and safety risks. Air fresheners are available in various forms, such as sprays, scented oils, reed diffusers, solids, gels, and plug-in devices. The most common types are aerosol sprays and plug-in air fresheners.
Aerosol sprays use compressed gas propellants like butane, propane, or nitrogen, which are flammable. There have been reported cases of burns caused by flammable aerosol sprays that ignited due to a nearby flame. In one case, a woman suffered burns to her face, ears, and scalp when the spray air freshener she was using near a cigarette ignited. It is important to note that the use of aerosols has declined due to health and environmental concerns, and manufacturers have since reformulated air fresheners to use alternative delivery methods.
Plug-in air fresheners can also be a fire hazard. These devices usually contain a concentrated solution of oily fragrance that is gradually warmed and released, or an aerosol spray that is automatically released at set intervals. While the oil should be warm and not hot to the touch, it still poses a potential fire risk. There have been incidents where plug-in air fresheners have caught fire or started smoking, leading to dangerous situations.
In addition to the flammability risks, air fresheners can also have adverse effects on health and the environment. Inhaling small amounts of most air fresheners is typically not harmful, but ingesting gel-type evaporative beads or reed diffuser solutions can cause serious health issues. The toxic effects can range from minor irritation to life-threatening consequences, especially in children. Furthermore, air fresheners release volatile organic compounds (VOCs) into the air, contributing to indoor air pollution and posing potential health risks, especially with long-term exposure.
Therefore, it is crucial to be cautious when using air fresheners, particularly those with flammable components or chemicals that may have negative health impacts. It is important to follow safety guidelines, keep these products out of the reach of children and pets, and be mindful of potential hazards to minimise risks associated with their use.

Removing perfume odours from a room
Airing out a room is a simple and effective way to remove perfume odours. Open windows and doors to allow cross-ventilation, and switch on fans to boost airflow and help clear the odours more quickly. Exhaust fans in kitchens and bathrooms can also help pull the air and scent out of your space more efficiently.
To speed up the process, you can place bowls of natural deodorisers like baking soda, activated charcoal, or coffee grounds around the room. These will continue to absorb and neutralise odours, ensuring your space smells fresh by morning.
For a deeper clean, you can use a steam cleaner on carpets and upholstery to remove embedded fragrances. You can also spray a mixture of vinegar and water on hard surfaces like tables and countertops. Wipe them down with microfiber cloths to leave everything streak-free and fresh. If perfume has gotten into fabrics, try covering them with a generous layer of baking soda. Let it sit for 15-30 minutes to soak up the odour, then vacuum well. You can also add around half a cup of baking soda to the wash for bed linens and curtains to effectively remove strong smells.
For a touch of ambience, use essential oil diffusers or electric burners to introduce subtle, pleasant aromas that can help mask any remaining odours.
