There is growing concern that certain chemicals found in perfumes could be disrupting our hormones and causing other health issues. The endocrine system, which includes the pituitary gland, thyroid, ovaries, and testes, regulates hormones in our bodies. Endocrine-disrupting chemicals (EDCs) found in perfumes can interfere with the endocrine system by mimicking hormones and triggering inappropriate responses. While not all fragrances are harmful, some contain unregulated and potentially toxic chemicals such as parabens, phthalates, and synthetic musks, which can lead to health issues. The fragrance industry, particularly in the US, is largely unregulated, allowing manufacturers to label their products simply as fragrance without disclosing the specific chemicals used. However, studies have found endocrine disruptors and other harmful substances in popular perfumes, raising concerns about their impact on our health and the environment.

What You'll Learn
Endocrine-disrupting chemicals (EDCs)
The main issue with EDCs is that they can "trick a receptor by mimicking a hormone." This can lead to an inappropriate hormone response or block the activation of natural hormones, causing potential health issues. For example, EDCs have been linked to infertility and an increased risk of hormone-related cancers, including thyroid, prostate, testicular, uterine, ovarian, and breast cancer.
EDCs can also have neurological effects, especially for pregnant women and young children, potentially affecting brain development and increasing the risk of neurobehavioral outcomes like ADHD. Other health concerns include metabolic issues (insulin resistance and weight gain), adverse reproductive health outcomes (decreased sperm count), skin irritation, allergic reactions, and potential damage to the environment.
Some common EDCs found in fragrances include parabens, phthalates, octoxynols, nonoxynols, and synthetic musk compounds. These chemicals can be found in perfumes, air fresheners, candles, face wash, shampoo, skin care products, and other household items. To avoid potential exposure to EDCs, consumers can choose products labelled "phthalate-free," "paraben-free," or "BPA-free," opt for natural essential oils and botanical extracts, and look for transparent ingredient lists and third-party certifications.

Synthetic fragrances
The fragrance industry is mostly self-regulated, and manufacturers are not required to disclose what is in their fragrances. They can simply label their products as "fragrance" even if there are dozens of different compounds included in the blend. This lack of transparency makes it impossible to know what consumers are exposing their bodies to. According to the Environmental Working Group (EWG), the word "fragrance" can capture over 3,163 different chemicals, a quarter of which the EWG has identified as being moderately to severely hazardous to human health.
Some of the chemicals used in synthetic fragrances that can disrupt hormones include:
- Parabens: These are common preservatives used by beauty companies that mimic estrogen, the primary female sex hormone responsible for the proper function of the menstrual cycle and growth of female sexual organs. Parabens can mix with estrogen and disrupt the reproductive and hormonal systems of the body. They have also been linked to metabolic and reproductive health issues, including PCOD/PCOS and painful conditions like endometriosis.
- Phthalates: These preservatives are known to affect thyroid function and reproductive health. They can interfere with the release of natural hormones or cause their excess production.
- Synthetic musks: These chemicals mimic the natural scent of musk and are known to accumulate in the body, the environment, and fat cells. They can create endocrine disruption, carcinogenic effects, and allergic reactions.
- Octoxynols and nonoxynols: These emulsifiers can affect hormone balance and cause allergic reactions.
- Volatile Organic Compounds (VOCs): Gases like formaldehyde are emitted from perfumes and other products. Short-term exposure can cause headaches, dizziness, or irritation of the eyes, nose, and throat, while long-term exposure can increase the risk of cancer.
Until laws change or more endocrine-disrupting chemicals are banned, consumers can protect themselves by choosing products labeled "phthalate-free," "paraben-free," or "BPA-free." It is also recommended to avoid fragrances and personal care products that list "fragrance" as an ingredient and instead opt for natural essential oils and botanical extracts.

Lack of transparency in the fragrance industry
The fragrance industry has traditionally been shrouded in secrecy, with perfume formulas treated as industry secrets. Manufacturers are not required to disclose what goes into their fragrances, and can simply label the long list of ingredients as "fragrance". This lack of transparency makes it impossible for consumers to know what they are exposing themselves to.
While the fragrance industry has started to move towards transparency, spurred by expanding regulations and changing consumer attitudes, there is still a long way to go. Regulatory bodies are increasingly mandating the disclosure of more ingredients to ensure consumer safety, but lobbying by industry trade associations has blocked efforts to federally require full ingredient disclosure.
The fragrance industry is mostly self-regulated, with the IFRA (the industry's self-governing agency) setting the rules. However, there are brands and perfumers doing the work to be more transparent. For example, Les Indémodables lists the exact percentages of raw materials used in each scent, and Régime des Fleurs and Chronotope go beyond industry standards for sustainability, perfumer attribution, and transparency.
Consumers are increasingly demanding to know more about raw ingredients, perfumers, and sustainability initiatives. They want to purchase products that align with their values of health, sustainability, and ethical production, but they need clear information to do so. As conscious consumerism continues to shape markets, the fragrance industry will need to adapt to meet the changing demands of its customers.

Increased risk of hormone-related cancers
The use of perfumes and other fragranced products has been linked to an increased risk of developing hormone-related cancers. Endocrine-disrupting chemicals (EDCs) are believed to be the main culprits. EDCs can interfere with the endocrine system, which includes glands like the pituitary, thyroid, ovaries, and testes, that secrete hormones and regulate bodily functions.
EDCs can mimic hormones and inappropriately trigger or block hormone responses in the body. This interference with hormone signaling and transport can lead to adverse health effects. For instance, studies have shown that exposure to EDCs may increase the risk of thyroid, prostate, testicular, uterine, ovarian, and breast cancer.
In 2018, the Breast Cancer Prevention Partners tested 338 fragrance chemicals found in 25 popular personal care products. They discovered that many of these chemicals were known carcinogens, and 99 of them had links to at least one health concern.
The fragrance industry is largely self-regulated, and manufacturers are not required to disclose all the ingredients in their products. This makes it challenging for consumers to make informed choices and avoid potentially harmful chemicals. However, consumers can take some steps to protect themselves, such as choosing products labeled phthalate-free, paraben-free, or BPA-free, and opting for natural alternatives.

Neurological effects
While there is debate on the topic, some sources claim that certain chemicals found in perfumes can have neurological effects on the human body. These effects can range from dizziness, convulsions, headaches, fainting, and imbalance to more severe outcomes such as autism, depression, and neurological problems in children.
One study found that exposure to phthalates during childhood was associated with lower levels of active thyroid function in 3-year-old girls, potentially leading to neurological and behavioural issues later in their lives. Phthalates are a group of chemicals used in hundreds of products to make plastics more flexible. The phthalate commonly used in fragrances is diethyl phthalate (DEP), which has been deemed safe for human use by the FDA and CDC.
Endocrine disruptors are molecules that can interfere with the proper functioning of the endocrine system, which is made up of glands that secrete hormones. These disruptors can either interfere with the release of natural hormones or cause their excess production. Synthetic fragrances, commonly found in perfumes, are one such example of endocrine disruptors.
The effects of endocrine disruptors are not always linear, meaning that the amount of the substance present does not always determine the effect on the endocrine system. However, it is important to note that the majority of lab-based studies tend to use perfume ingredient doses far higher than what one would spritz on their skin.
While the specific mechanisms of action for mixtures are not well understood, it is believed that endocrine disruption occurs when several molecules simultaneously bind to a hormone receptor. This can then inappropriately turn on a hormone response or block activation, preventing normal hormonal processes in the body.
To avoid potential neurological effects from toxic fragrances, one can opt for products that use natural essential oils, have transparent ingredient lists, and third-party certifications.
