There are thousands of chemicals used in perfumes and colognes, and some of these have been linked to harmful health effects, including endocrine disruption, allergies, asthma, and even cancer. While there is no direct evidence that perfumes cause cancer in humans, studies have shown that certain fragrance ingredients can cause cancer in laboratory animals, and some perfumes contain chemicals that are known human carcinogens. With the lack of transparency in the fragrance industry regarding ingredient disclosure, it is challenging to determine the exact health risks associated with perfume use. However, some sources claim that the risk of cancer from perfume exposure is low compared to other carcinogenic substances we encounter daily.
| Characteristics | Values |
|---|---|
| Cancer-causing agents in perfumes | Styrene, phthalates, parabens, triclosan, salicylates, terpenes, aldehydes, benzene, toluene, aluminium-based salts, beta-myrcene, and thousands of other chemicals |
| Health issues | Allergies, asthma, breast cancer, endocrine cancer, endocrine disruption, reproductive harm, respiratory harm, neurotoxicity, nervous system damage, migraines, autism, dermatitis, cardiovascular disease, thyroid issues, immune system dysfunction |
| Regulatory issues | No legal requirement to list ingredients, companies argue that fragrance mixtures are trade secrets, only 11 out of 10,000 chemicals banned or restricted by the US FDA, lack of safety data, outdated federal laws |
| Recommendations | Wear appropriate personal protective equipment, avoid undiluted essential oils on skin, avoid lavender/tea tree oil on young boys, choose safer products, support Rep. Jan Schakowsky's Safe Cosmetics and Personal Care Products Act |
| Other considerations | Natural fragrances can also be harmful, exposure to multiple products with fragrances increases risk, fragrances in household products also contribute to exposure |

Perfume ingredients linked to cancer
While there is no direct evidence that perfume causes cancer in humans, certain ingredients in perfumes have been linked to cancer. Perfumes are a mixture of several chemicals, and some of these chemicals are known to cause cancer, hormone disruption, and reproductive harm.
The International Fragrance Association (IFRA) has a palette of approximately 4,000 fragrance ingredients that are used to create the scents in personal care products, cosmetics, cleaning products, and fine fragrances. However, not all of these ingredients are safe. Some common pollutants in perfumes include phthalates, parabens, triclosan, salicylates, terpenes, aldehydes, benzene, toluene, styrene, and aluminum-based salts. These pollutants have been linked to various health issues, including allergies, asthma, cardiovascular disease, central nervous system damage, breast cancer, endocrine cancer, respiratory disorders, reproductive issues, thyroid problems, and immune system dysfunction.
One particular ingredient, styrene, has been identified by an expert panel as a human carcinogen. Styrene is a chemical building block used in a wide range of everyday products, including perfumes and household care products. The issue is exacerbated by the "`fragrance loophole'" in federal labeling laws, which allows companies to list fragrance ingredients under the generic term "fragrance" without disclosing specific chemicals. This makes it difficult for consumers to identify and avoid potentially harmful ingredients.
While the link between perfume ingredients and cancer is concerning, it is important to note that the concentration of harmful ingredients in consumer products is typically much lower than in laboratory studies. Regulatory bodies and expert panels worldwide evaluate and assess the safety of fragrance ingredients to protect consumers. However, there is a growing call for reform in the regulation of these products to ensure that only safe ingredients are used and that consumers have access to full ingredient disclosure.

Lack of ingredient transparency
The fragrance industry has traditionally been shrouded in secrecy, with regulatory frameworks classifying fragrances as trade secrets. However, there is a growing trend towards transparency due to changing consumer attitudes and expanding regulations. Consumers are becoming more conscious and informed about the products they use and are demanding more transparency from brands.
The term "fragrance" or "parfum" on an ingredient list is not an individual ingredient but rather an umbrella term for the dozens or even hundreds of chemicals that make up a product's fragrance. The International Fragrance Association (IFRA), a self-regulating body, has a list of over 3,000 ingredients used as fragrance compounds, but many of these chemicals lack safety data and have been linked to negative health effects, including cancer.
The "fragrance loophole" in federal labelling laws allows manufacturers to list fragrance ingredients under the generic term "fragrance" without disclosing the specific chemicals used. This makes it difficult for consumers to know exactly what they are putting on their bodies and increases the risk of exposure to potentially harmful chemicals.
Some brands, such as Skylar and Henry Rose, have started disclosing their entire ingredient lists to provide transparency to their customers. L'Oréal, the world's largest cosmetic company, also announced in 2018 that it would begin disclosing the secret fragrance ingredients in its products. However, their announcement lacked specifics, and they have yet to provide detailed information on which products and brands will be covered by this new policy.
The lack of ingredient transparency in the fragrance industry makes it challenging for consumers to make informed decisions about the products they purchase. It also raises concerns about the potential health risks associated with exposure to undisclosed chemicals in fragranced products. To address these concerns, regulatory bodies are increasingly mandating the disclosure of more ingredients, and consumers are demanding more transparency from brands to ensure their safety and align with their values.

Harmful effects of 'natural' perfumes
Natural perfumes are extracted from plants, lichens, seaweed, and special oils obtained from different parts of a plant. They can also be divided into aromatic compounds and musk. However, the term "natural" does not always mean safe. Natural fragrances can contain harmful constituents such as endocrine disruptors, carcinogens, and allergens.
Essential oils, which are a type of natural perfume, are naturally occurring complex mixtures that are highly variable in their chemical composition. Their composition depends on factors such as geographic origin, extraction method, season of harvest, and other biological conditions.
Natural perfumes can contain Volatile Organic Compounds (VOCs), which can be irritating and disruptive to our airways and have other negative health effects. VOCs are also harmful to the atmosphere. Terpenes, which are natural or synthetic fragrance compounds, can react with ozone and the hydroxyl radical to produce secondary pollutants like formaldehyde and ultrafine particles that can persist in indoor air.
Some fragrance ingredients have been shown to cause cancer in laboratory animals, but at much higher concentrations than those used in consumer products. An expert panel has also confirmed that styrene, a chemical used to produce a wide variety of everyday products, can cause cancer.
Other harmful effects of natural perfumes include allergic reactions such as itchy/watery eyes, congestion, a runny nose, throat irritation, coughing, and wheezing. They can also cause skin allergies, nervous system damage, and migraine headaches.

Contaminants in perfumes
The use of perfumes and colognes can have side effects on consumers. A study identified 562 relevant articles, and after a screening process, 37 articles were included in the study. The results showed that phthalates, aldehydes, parabens, and aluminum-based salts are the most important contaminants in aromatic products that cause side effects such as allergies, reproductive disorders (especially in males), skin allergies, nervous system damage, and migraine headaches.
Terpenes (e.g. beta-pinene, limonene, and alpha-pinene) are important contaminants in aromatic products that can react with ozone and spectrum to form secondary contaminants such as formaldehyde, acetaldehyde, and secondary organic aerosols. Formaldehyde and fine particles may also be created as a result of the high content of terpenoids in air fresheners. These contaminants can affect the health of other people by producing secondary pollutants in indoor air.
Most perfumes contain high amounts of ethanol, which can be dangerous for children if ingested. The most toxic ingredient in perfumes, colognes, and aftershaves is often ethanol or isopropyl alcohol. The scented ingredients in perfumes are infused into these alcohols to preserve and stabilize the product's scent.
Fragrances can consist of approximately 4,000 chemicals used by the fragrance industry to formulate scents for use in personal care products, cleaning products, perfumes, and home care products. Many fragrance chemicals are linked to cancer, birth defects, hormone disruption, and other chronic health problems.
It is important to note that there is currently no evidence linking the use of fragranced products to an increased risk of cancer in humans. However, some fragrance ingredients have been shown to cause cancer in laboratory animals at very high concentrations.

Allergies and other side effects
While there is no direct evidence that perfume causes cancer, some of its ingredients have been linked to this and other chronic illnesses. The fragrance in perfumes is formulated from about 4,000 chemicals, some of which are safe, while others have never been tested for safety. The International Fragrance Association (IFRA) estimates that 900 expert perfumers use these ingredients to create 60,000 to 80,000 unique proprietary fragrance blends annually.
Perfumes and colognes have been found to contain several toxic chemicals, including phthalates, parabens, triclosan, salicylates, terpenes, aldehydes, benzene, toluene, styrene, and aluminum-based salts. These pollutants have been linked to adverse health effects such as asthma, allergies, cardiovascular disease, central nervous system damage, endocrine cancer, respiratory disorders, reproductive harm, thyroid, adrenal gland function, and immune system issues.
In a study conducted in skin clinics on patients with allergic dermatitis, perfume was considered the second main cause of allergic reactions. Another study in European centers found that 1.5–3% of contact allergies were caused by perfume. Different compounds in aromatic products can cause allergic symptoms in humans, and perfumes have been mentioned in several studies as one of the main allergens.
In addition to allergies, perfumes have been linked to other side effects, including breast cancer, skin allergies, neurological disorders, and migraine headaches. Studies have also shown that aromatic products emit more than 100 volatile organic compounds (VOCs), which can seriously threaten human health.
It is important to note that the specific effects of perfumes on individuals may vary depending on factors such as age, gender, race, amount of substance consumed, and duration of use.
