Fragrances are everywhere, from air fresheners and candles to perfumes and colognes. But are these fragrances bad for our health? Fragrances are often used as a placeholder for a wide range of volatile organic compounds (VOCs) and other toxic chemicals. VOCs are organic chemicals that can evaporate at room temperature, a process called off-gassing, which can reduce air quality. Some common VOCs found in fragrances include ethanol, acetone, acetaldehyde, and camphor, which are classified as hazardous or toxic. Other toxic chemicals found in fragranced products include parabens and phthalates, which can cause reproductive and neurological issues. While fragrances may enhance our enjoyment of products, they can also be a source of indoor and outdoor air pollution, with potential adverse health effects.

Fragrance products can emit a bouquet of VOCs
The detection of VOCs in these products is a cause for concern, as they can be a source of indoor and outdoor air pollution. VOCs can be particularly harmful to individuals with respiratory problems, and they can also trigger asthma and allergy symptoms. Furthermore, some VOCs are classified as toxic or hazardous by federal laws and can react with ozone in ambient air to form dangerous secondary pollutants, such as formaldehyde.
One example of a VOC commonly found in fragrance products is phthalates. Phthalates are used as a solvent and stabilizer in fragrances, and they have been linked to reproductive and neurological disorders. Other toxic chemicals included in fragranced personal care products include parabens, which may be harmful endocrine disruptors, and formaldehyde-releasing preservatives, which are known skin irritants.
Due to the potential health risks associated with VOCs, it is important to be aware of their presence in fragrance products. While manufacturers are not required to disclose the ingredients that make up their scents, consumers can choose to purchase from clean brands that use low-toxic or non-toxic ingredients. By being mindful of the ingredients in fragrance products, individuals can make informed decisions about their health and well-being.

VOCs in fragrances can cause health issues like respiratory diseases and cancer
Fragrances are a formulation of dozens of chemicals, including volatile organic compounds (VOCs). VOCs are emitted from fragrances and related products during indoor use, and the constituents of fragrance emissions vary significantly. For example, ethanol, propylene glycol, and 3-ethylbenzaldehyde are common VOCs emitted from chemically synthesized fragrances. While fragrances can provide an enjoyable aroma or mask an unwanted odor, some VOCs in fragrances can cause adverse health effects, including respiratory diseases and cancer.
People spend most of their time indoors, and many use fragrances in closed restrooms and bathrooms at home and in public spaces for masking odors. However, VOCs emitted from indoor fragrances have been reported to pose a risk to human health. Lower indoor air change rates were associated with significantly higher emitted concentrations of VOCs. 3-Ethylbenzaldehyde, a common VOC emitted from fragrances, is a strong respiratory irritant.
In addition to respiratory issues, VOCs in fragrances have been linked to other health problems. For example, Steinemann et al. (2010) identified 133 unique VOCs among 25 products, some of which are classified as toxic or hazardous by federal laws. These VOCs can react with ozone in ambient air to form dangerous secondary pollutants, such as formaldehyde. Furthermore, fragrance chemicals can interfere with the neuroendocrine-immune axis, promoting cancer and developmental problems. Disease symptoms related to fragrance chemicals may include neural disturbances (e.g., headaches, depression, and migraines), skin and airway hypersensitivity, reproductive issues, and increased risk of certain cancers.
The specific health effects of VOCs in fragrances can vary depending on the frequency and quantity of exposure, as well as evaporation and diffusion rates. While most fragrance chemicals are assigned a low risk through risk assessment and safety evaluation, secondary pollutants that negatively affect human health can still emerge. Additionally, undisclosed fragrance-related chemicals in product formulations can trigger or intensify episodic and chronic symptoms of allergies, headaches, and cardiovascular diseases in sensitive individuals.
It is worth noting that not all fragrances are equally harmful. Thanks to public awareness, many cosmetic and home goods producers have stopped using harmful chemicals. Consumers can enjoy candles, air fresheners, and perfumes without worrying about VOCs by choosing clean brands that use low-toxic or non-toxic ingredients.

VOCs in fragrances are often undisclosed due to trade secret laws
Fragrances are incredibly popular today, with candles, air fresheners, and perfumes being used widely. However, the presence of Volatile Organic Compounds (VOCs) in fragrances has raised concerns. VOCs can cause health issues, including respiratory diseases and even cancer.
While some companies, like SC Johnson, have started disclosing fragrance ingredients, the fragrance industry has historically kept its formulas a closely guarded secret, claiming that trade secrets are necessary to protect intellectual property. This exemption from ingredient disclosure requirements is allowed under consumer product regulations globally.
The term "fragrance" on ingredient lists often hides a multitude of chemicals—anywhere between 10 to 50 in most products. These chemicals are not disclosed because they are considered trade secrets under the US Fair Packaging and Labeling Act. However, this secrecy has been challenged by the improving accuracy of analytic technologies, which can now reveal a fragrance's chemical composition.
Additionally, the safety of fragrance chemicals is not comprehensively monitored by any governmental agency globally. Instead, the industry self-regulates and establishes its own safety guidelines, leading to concerns about the potential toxicity of certain ingredients, such as phthalates, synthetic musks, and styrene.
While trade secret laws can protect information indefinitely, once the information is acquired or independently developed by another party, it is no longer secret, and its original owner cannot prevent others from using it. This vulnerability to reverse engineering has made trade secret protection increasingly difficult for the fragrance industry to maintain.

VOCs are organic chemicals trapped in products during manufacturing
Volatile organic compounds (VOCs) are organic chemicals that are emitted as gases from solids or liquids. They are present in various household, industrial, and commercial products, and their accumulation in air and water has become a significant concern. VOCs are trapped in products during manufacturing and can be released during the use of these products, a process known as off-gassing.
Some common sources of VOCs in the home include unused chemicals such as paints, varnishes, solvents, adhesives, and caulks. Household furnishings like carpets, upholstered furniture, and composite wood items can also off-gas VOCs, especially when new. Additionally, personal care products, cleaning products, and building materials can contain VOCs.
Fragrances are a significant source of VOCs. The term "fragrance" on ingredient lists often encompasses various chemicals, including VOCs, that companies are not required to disclose. Phthalates, for example, are VOCs commonly used to stabilize fragrances, and they have been linked to reproductive and neurological disorders. Fragranced products, such as air fresheners, candles, and perfumes, can emit VOCs into the air, potentially causing health issues for those who use them.
The health effects of VOCs depend on their concentration and exposure time. Some VOCs are classified as toxic or hazardous, and they can cause eye, nose, and throat irritation, headaches, nausea, dizziness, and difficulty breathing. Long-term exposure to certain VOCs can lead to damage to organs like the liver, kidneys, and central nervous system, and some VOCs are even linked to cancer.
To reduce exposure to VOCs, it is recommended to limit the use of products containing them, improve ventilation, and opt for low-VOC alternatives when possible.

VOCs in fragrances can cause indoor and outdoor air pollution
Volatile organic compounds (VOCs) are a large group of chemicals found in many household and personal care products. They are called volatile organic compounds because they evaporate or "off-gas" at room temperature and pressure. VOCs are emitted by a wide range of products, including paints, varnishes, cleaning agents, and personal care products like fragrances, hair sprays, and air fresheners.
VOCs in fragrances can cause both indoor and outdoor air pollution. When released into the air, these compounds can react with other chemicals and sunlight to form ozone pollution, which is harmful to the environment and human health. According to a study by the National Oceanic and Atmospheric Administration (NOAA), the use of scented products emits the same amount of chemical vapors as petroleum emissions from cars, despite cars burning 15 times more petroleum as fuel. This highlights the significant impact of VOCs in fragrances on air pollution.
The presence of VOCs in fragrances has been confirmed by various studies. For example, Potera (2011) quoted Steinemann et al. (2010), noting that "133 unique VOCs [were] identified among 25 products," including fragrances. Additionally, Balducci et al. collected chemicals emitted from fragrances in two Italian indoor environments and detected the presence of carvone and camphor, as well as several endocrine disruptors. Du et al. also found d-limonene and β-pinene in lemon essential oil, with concentrations of 107 ± 36 and 24.1 ± 5.6 ppb, respectively.
The health risks associated with VOCs in fragrances are significant. VOCs can cause respiratory issues and have been linked to more severe health problems, including cancer. People with existing respiratory conditions, such as asthma, young children, the elderly, and those with heightened sensitivity to chemicals, are particularly vulnerable to the effects of VOCs.
To reduce exposure to VOCs in fragrances, it is recommended to increase ventilation by opening doors and windows and using fans to maximize fresh air circulation. Additionally, individuals can opt for clean brands that use low-toxic or non-toxic ingredients for their fragrances, perfumes, and air fresheners.
