Some perfumes contain common ingredients that can cause reactions, such as citronella, an insect repellent, which can cause skin irritation or respiratory issues in sensitive individuals. Synthetic fragrances are complex mixtures of numerous chemicals, with the average fragrance product containing around 14 additional ingredients not disclosed on the product label. These undisclosed ingredients may include chemicals associated with hormone disruption, allergic reactions, and other hazardous properties. One such chemical is diethyl phthalate, which is linked to sperm damage in human epidemiological studies. Another example is musk ketone, which concentrates in human fat tissue and breast milk. The use of these chemicals in perfumes can contribute to their resemblance to pesticides in terms of scent and potential health impacts.

What You'll Learn
Perfumes may contain volatile organic compounds (VOCs)
VOCs are emitted from fragrances and related products during indoor use, and the constituents of fragrance emissions can vary significantly. Some VOCs, such as ethanol, propylene glycol, and 3-ethylbenzaldehyde, have been identified as potential health hazards. 3-Ethylbenzaldehyde, for example, is a strong respiratory irritant. Other VOCs, such as limonene and pinene, are naturally occurring and can be found in citrus fruits and pine trees, respectively. However, when these compounds react with ozone in the air, they can form dangerous secondary pollutants, such as formaldehyde.
The potential health risks of VOCs in perfumes are a concern, especially for those who use scented products frequently or in enclosed spaces. In a telephone survey by Caress and Steinemann (2009), 19% of respondents reported unspecified health problems, and 11% noted irritation, which they subjectively ascribed to the use of scented laundry products. While these self-assessments may not be objectively confirmed by medical testing, they highlight a potential link between scented products and health issues.
Furthermore, the synthetic fragrances commonly found in perfumes are complex mixtures of numerous chemicals, with an average of around 14 additional ingredients that are not disclosed on product labels. This lack of transparency makes it difficult for consumers to make informed choices about the potential risks associated with the use of certain perfumes.
While the presence of VOCs in perfumes can contribute to their scent, it is important to be aware of the potential risks associated with these compounds. Proper ventilation and seeking alternatives with fewer synthetic ingredients can help mitigate the potential health hazards of exposure to VOCs in perfumes.

Pesticides may be toxic to humans
The use of pesticides has become a growing concern for human health and the environment. Pesticides are chemical constituents used to prevent or control pests, including insects, rodents, fungi, weeds, and other unwanted organisms. While typical household pesticide use may be safe in normal amounts, frequent spraying can elevate exposure risks. Even with very toxic pesticides, the risk remains low if there is no direct exposure. However, symptoms like irritation and discomfort may arise from even slight exposure.
The health effects of pesticides depend on the type of pesticide and the level of exposure. Some pesticides affect the nervous system, causing headaches, nausea, dizziness, vomiting, chest pain, diarrhea, muscle pain, confusion, and in severe cases, convulsions, difficulty breathing, involuntary urination, coma, and death. Organophosphates and carbamates, for example, are pesticides that act like nerve gas, interfering with nerve signal transmission. Pyrethroids, on the other hand, are synthetic chemicals that are toxic to the nervous system, and there are concerns about their impact on fetal development.
Other health effects of pesticides include acute and chronic toxicities, with some pesticides causing neurotoxicity, mutagenicity, carcinogenicity, teratogenicity, and endocrine disruption. Endocrine disruptors are chemicals that interfere with important bodily functions by mimicking or blocking hormones. Exposure to these chemicals has been linked to cancer, sterility, and developmental problems in animals, with similar impacts associated with human exposure. Children are especially vulnerable to pesticide exposure due to their developing organs, nervous systems, and immune systems. They are also more likely to be exposed through skin contact and inhalation.
Methyl benzoate (MB), a volatile organic compound (VOC) found in fermented apple juice, has been identified as a potential green pesticide. While MB is considered to be of low to moderate human toxicity by ingestion and inhalation, it is still a pesticide that needs to be registered with the EPA. MB is also used as a fragrance ingredient and preservative in personal care products, contributing to the chemical smell of some perfumes.

Some perfumes contain undisclosed chemicals
According to the Environmental Working Group (EWG), the average fragrance product tested contained 14 secret chemicals not listed on the label. These undisclosed ingredients include chemicals associated with hormone disruption, allergic reactions, and other adverse health effects. For example, diethyl phthalate, found in 97% of Americans, has been linked to sperm damage in human epidemiological studies, while musk ketone concentrates in human fat tissue and breast milk.
The use of synthetic fragrances, primarily derived from petroleum, is of particular concern. These fragrances are cheap and abundant, contributing to decreasing indoor air quality and increasing personal exposure to potentially harmful chemicals. Synthetic fragrances are complex mixtures of numerous chemicals, and even proper storage and use may not prevent their negative effects on human health.
In addition to the potential health risks, undisclosed chemicals in perfumes can also impact the environment. For example, methyl benzoate, a compound found in some perfumes, is also an effective green pesticide. While it is considered environmentally friendly, it can be toxic to humans through ingestion and inhalation.
The presence of undisclosed chemicals in perfumes highlights the need for better regulation and transparency in the fragrance industry. While some companies have voluntarily started disclosing all the chemicals in their products, more needs to be done to ensure the safety of consumers and the environment.

Fragrances can deteriorate over time
Fragrances can indeed deteriorate over time, with the oxidation process causing the scent to become sour, acidic, or metallic. The alcohol content in perfumes acts as a preservative, so the more alcohol in the formula, the better the longevity. However, exposure to heat and light can accelerate the evaporation of the alcohol, causing the fragrance to expire faster.
To prolong the life of a fragrance, it should be stored in a cool, dry, and dark place, such as a bedroom drawer, closet, or fridge. Unopened bottles kept in such conditions can last for years, with some sources stating a range of one to ten years, while others state that some perfumes can last up to two decades. Once opened, a bottle of perfume can last anywhere from three months to five years, depending on its construction, packaging, and storage conditions.
It is important to note that perfumes do not have a set expiry date, and whether a perfume has expired can be tricky to determine. The most obvious way to tell if a perfume has gone bad is to test its scent and look for any changes. A spoiled fragrance may emit a sour, metallic, or vinegar-like odour, or it may smell flat or dull. The typical signs of rancid perfume include an unpleasant scent, often described as musty or mouldy, regardless of the original notes.
In addition to changes in scent, visual indicators can also signify that a perfume has expired. A change in colour, such as a darker or more opaque appearance, can indicate that a perfume has gone bad. Another sign is a decrease in the volume of liquid in the bottle, which may be due to the evaporation of the alcohol content.
Overall, while fragrances can deteriorate over time, proper storage and attention to signs of expiration can help prolong their life and enhance the fragrance experience.

Citronellol is a common ingredient in perfumes and insect repellents (bug spray)
Some perfumes may give off a chemical-like smell due to the presence of volatile organic compounds (VOCs). One such VOC is methyl benzoate, which has a wintergreen-spicy, floral-fruity aroma and is used in perfumes and cosmetics. However, it is also being investigated as a potential green pesticide due to its toxicity against various insect pests.
Citronellol, or dihydrogeraniol, is another common ingredient in perfumes and insect repellents. It is a natural acyclic monoterpenoid with a fresh, grassy, citrus, or floral smell. Citronellol is found in citronella oils, which are derived from the Cymbopogon nardus plant, also known as the citronella or mosquito plant. The oil has been recognized as safe by the US Food and Drug Administration and is used as an insect repellent, especially against mosquitoes. It is also an active component in mosquito candles and sprays.
Citronellol is produced by the partial hydrogenation of geraniol or nerol over a copper chromite catalyst. It has two forms, (+)-citronellol and (-)-citronellol, which produce different scents. One form has a citrus smell, while the other has a sweet floral scent reminiscent of roses. Citronellol is also known for its antifungal properties and is used in skincare and beauty products to improve skin appearance and reduce signs of fine lines.
While perfumes containing citronellol can provide a pleasant fragrance, it is important to note that perfumes with expired fragrances may emit a sour, metallic, or vinegar-like odor. Proper storage helps prolong the life of perfumes, but all fragrances will eventually deteriorate.
