Fragrances are ubiquitous in modern life, from perfumes and colognes to cleaning products and air fresheners. While fragrances are designed to create pleasing scents or mask unpleasant odours, there are growing concerns about their potential health and environmental risks. Fragrances can contain a mix of more than 3,500 chemicals, some of which are toxic and can cause a range of health issues, including allergies, endocrine disruptions, cancer, neurotoxicity, infertility, and respiratory problems. The fragrance industry is loosely regulated, and manufacturers are not required to disclose all ingredients, making it challenging for consumers to make informed choices. With increasing awareness of the potential dangers, many are seeking safer alternatives to fragranced products.

What You'll Learn
Fragrance ingredients are often undisclosed
Fragrances are made up of a mix of more than 3500 chemicals, which give personal care, cleaning, and other products their unique smell. However, manufacturers are not required to list these ingredients on product labels, and often only the word "fragrance" is used, which can hide a cocktail of more than 100 toxic ingredients. This is because fragrances are considered trade secrets.
The fragrance industry regulates itself, and safety testing does not need to be confirmed by regulators before products are sold. As a result, so-called ""natural fragrances" can be just as toxic as synthetic fragrances. Fragrance chemicals can cause a range of health problems, including allergies, endocrine disruption, cancer, neurotoxicity, infertility, and asthma. They can also be harmful to the environment, with chemical vapors in fragrances, called volatile organic compounds, causing ozone pollution and forming fine particulates.
In the United States, the Food and Drug Administration (FDA) regulates fragrance ingredients as cosmetics if they are in a cosmetic product and function to provide scent. However, the FDA does not approve or test cosmetic products, including fragrances, before they are available for sale. Manufacturers are legally responsible for ensuring product safety when used as intended.
In Europe, the fragrance industry is heavily regulated, and most brands will need to abide by these regulations if they want to sell their goods in the EU. For example, benzyl salicylate, a fragrance allergen and potential endocrine disruptor, must be labeled on products in the EU.
To avoid fragrances and their potential health risks, the Environmental Working Group advises consumers to read the word "fragrance" or "parfum" and translate it to mean "hidden chemicals". They recommend choosing fragrance-free products and checking the ingredient list, as manufacturers sometimes use masking fragrances to cover the chemical smell of their products.

Fragrance chemicals can be toxic
Fragrances are made up of a mix of more than 3,500 chemicals, which give personal care, cleaning, and other products their unique smell. However, manufacturers are not required to list their fragrance ingredients on product labels, and these "fragrance" chemicals can be toxic.
The chemicals are rarely, if ever, listed on the ingredients label because companies are not required to do so, as they are considered a trade secret. Instead, they are simply grouped under the umbrella terms "fragrance", "perfume", "parfum", or "aroma". The Environmental Working Group (EWG) advises consumers to read these terms and translate them to mean "hidden chemicals".
Fragrance chemicals are linked to a range of health problems. They can disrupt the hormone system, harm the reproductive system, and cause allergic reactions in both children and adults. For example, benzyl salicylate is a fragrance allergen and a potential endocrine disruptor. Fragrances can also cause contact dermatitis, an allergic skin reaction.
In addition, fragrance chemicals are bad for the environment. Chemical vapors in fragrances, called volatile organic compounds, can cause ozone pollution and form fine particulates, according to one study.
Some specific toxic fragrance chemicals include:
- Chloromethane, which can have acute and chronic effects on the nervous system and adversely impact the liver, kidneys, and skin.
- Dichloromethane, which is considered a human carcinogen and has been linked to mammary gland tumors in experimental animals.
- Diethyl phthalate (DEP), which is a dangerous irritant to the eyes, skin, and respiratory tract.
- Resorcinol, which can hurt the liver, kidneys, and spleen, and also affects the cardiovascular and nervous systems.
- Styrene, which is a designated carcinogen and has been linked to severe health problems such as damaging red blood cells and the liver.
- Synthetic musks, which are highly bioaccumulative and can disturb the hormone, reproductive, and organ systems.

Fragrance allergies and health risks
Fragrances are linked to a wide range of health risks. Fragrances can contain a mix of more than 3,500 chemicals, which are rarely listed on the product label. This is because fragrance ingredients are considered trade secrets and are not required to be disclosed.
Some of the chemicals used in fragrances are toxic and can cause detrimental health effects, including allergies, endocrine disruption, cancer, neurotoxicity, infertility, and asthma. These chemicals can also be harmful to the environment, causing ozone pollution and fine particulate matter formation.
One of the most common health issues associated with fragrances is contact dermatitis, an inflammatory skin reaction. Fragrances are the most frequent chemicals causing this condition. Other potential health risks include allergic reactions, such as irritation, burning, and stinging of the skin, eyes, nose, or throat.
Some specific chemicals found in fragrances and their associated health risks include:
- Benzyl salicylate: A fragrance allergen and potential endocrine disruptor.
- Butoxyethanol: A dangerous substance linked to kidney, liver, immune system, and nervous system damage and classified as a cancer-causing agent.
- Chloromethane: Can have acute and chronic effects on the nervous system and negatively impact the liver, kidneys, and skin.
- Dichloromethane: Linked to mammary gland tumors in animals and considered a human carcinogen.
- Diethyl phthalate (DEP): A dangerous irritant to the eyes, skin, and respiratory tract.
- Resorcinol: Toxic to the body, particularly the liver, kidneys, and spleen, and can also affect the cardiovascular and nervous systems.
- Styrene: Designated a carcinogen and linked to severe health problems such as damage to red blood cells and the liver, as well as injury to the brain and disruption of hormone balances.
It is important to note that the fragrance industry is self-regulated, and safety testing may not be confirmed by independent regulators before products are sold to consumers. However, there are exceptions, such as products bearing the EWG VERIFIED® mark, which indicates that they are free from specific chemicals of concern and meet strict transparency and health standards.

Fragrance regulation and safety standards
Fragrances are a mix of more than 3,500 chemicals, giving personal care, cleaning, and other products their unique smell. Fragrance chemicals are not benign and can cause a range of health problems. Some are phthalates, which can harm the reproductive system, while others, like styrene, are linked to cancer. Fragrance chemicals can also cause allergic reactions in both children and adults, as well as endocrine disruption.
IFRA Standards
The fragrance industry has developed a system to manage the safe use of fragrances: the IFRA Standards. The International Fragrance Association (IFRA) is a global trade organization that represents the fragrance industry and sets guidelines for the safe use of fragrances in consumer products. Established in 1973, IFRA works with fragrance houses, regulatory authorities, and scientific experts to develop and update standards that promote the safety and sustainability of fragrances. The IFRA Standards ban, limit, or set criteria for the use of certain ingredients, based on scientific evidence and consumer insights. These standards are recognised by government authorities and trade bodies worldwide and are compulsory for all IFRA members, who produce around 80% of the global volume of fragrances.
European Regulatory Requirements
Fragrance manufacturers operating in Europe must also comply with specific regulatory requirements set by the European Union (EU). These include the Registration, Evaluation, Authorisation, and Restriction of Chemicals (REACH) framework, which governs the use and handling of chemicals in consumer products, including fragrances. Under REACH, fragrance ingredients must undergo rigorous safety assessments to ensure they meet strict criteria for human health and environmental protection. This includes assessing the risks associated with exposure to individual ingredients and establishing safe limits for their use in consumer products.
US Regulations
In the US, the FDA regulates personal care products, including the fragrances they contain. However, fragrance and flavour ingredients can be listed simply as "Fragrance" or "Flavour" on product labels, as they are considered trade secrets. The Fair Packaging and Labeling Act (FPLA) law does not require companies to disclose trade secrets.
Compliance with IFRA standards and European regulatory requirements offers several benefits, including consumer safety, quality assurance, market access, and environmental responsibility.

Environmental impact of fragrances
The use of fragrances has various environmental repercussions. Firstly, the production and distribution of fragrances contribute to carbon emissions, with the cultivation of raw materials, manufacturing, and transportation all leaving a carbon footprint.
The chemical composition of fragrances is often undisclosed, with manufacturers not required to list ingredients, and this lack of transparency poses a significant issue. Many fragrance chemicals are toxic and harmful to both human health and the environment. These chemicals, known as volatile organic compounds (VOCs), can cause ozone pollution and form fine particulates, contributing to air pollution. The overuse of fragrances exacerbates this issue, impacting indoor and outdoor air quality.
Fragrance chemicals can also negatively impact water systems. For example, phosphates in fragrances can cause uncontrolled algae blooms in waterways, depleting oxygen levels and harming aquatic life. Other chemicals can reduce water surface tension, allowing pesticides and other toxins to enter the water more easily, which can be absorbed by plants and animals.
The use of natural ingredients in fragrances can also have environmental implications. Overharvesting and habitat disruption to obtain floral and botanical extracts can affect ecosystems.
Additionally, the packaging of fragrances, particularly perfumes, often involves excessive and non-recyclable materials, contributing to environmental pollution and waste.
Overall, the environmental impact of fragrances is significant and often underrecognized. The lack of transparency in the industry and the potential harm caused by fragrance chemicals highlight the need for sustainable practices, ethical sourcing, and eco-friendly packaging.
