Fragrances are a common feature of many personal care and cleaning products, with the average adult using 12 personal care products a day. However, the safety of these fragrances has been called into question. The fragrance industry is loosely regulated, with companies not required to list fragrance ingredients on product labels, and the industry self-regulates through the International Fragrance Association's (IFRA) code of practice. This code of practice restricts the use and concentrations of fragrance ingredients, but IFRA has no means to control its implementation. Fragrances can contain toxic chemicals that can cause a range of health issues, including allergies, endocrine disruption, cancer, and respiratory problems. These chemicals can also have negative environmental impacts, causing ozone pollution and fine particulate formation. While some argue for moderation and balance in fragrance use, others advocate for a complete switch to fragrance-free products to reduce exposure to toxic chemicals.

What You'll Learn
Fragrance chemicals and their impact on the environment
The term "fragrance" on a product label can represent a complex mixture of dozens, sometimes even hundreds, of chemical ingredients. The specific chemicals used to create these scents are often protected as "trade secrets", and as such, are not disclosed to consumers. This makes it difficult for consumers to make informed decisions about the safety of the products they are using.
Fragrance chemicals have been linked to a wide range of health risks, including allergies, asthma, neurological problems, and cancer. They are also associated with environmental risks. The chemical vapors found in fragrances, known as volatile organic compounds (VOCs), have been linked to ozone pollution and the creation of fine particulates. Synthetic musks, in particular, are of concern due to their ability to persist and bioaccumulate in the environment. Measureable levels of these synthetic musks have been detected in fish and sediments in the Great Lakes of North America.
The production and distribution of perfumes also contribute to carbon emissions, and excessive packaging, including non-recyclable materials, can lead to environmental pollution. The concept of "sillage", or the lingering scent left behind by a fragrance, can also contribute to air pollution and impact indoor air quality, especially when excessive amounts of perfume are used.
To reduce the impact of fragrance chemicals on the environment, consumers can opt for brands committed to eco-friendly production methods, sustainable supply chains, and minimal packaging designs. Consumers can also choose products that have been certified as healthier for the environment by independent third-party certification programs, or opt for fragrance-free products.

Health risks and endocrine disruption
Fragrances are a common ingredient in personal care and household cleaning products. They are also found in diffusers and air fresheners. The term "fragrance" on a product label can represent up to 100 different chemical ingredients. The specific ingredients used in fragrances are often not disclosed, making it difficult to understand the potential health risks associated with their use. This lack of transparency and regulation is particularly concerning given the potential for fragrance chemicals to cause serious chronic health issues.
The endocrine system is a network of glands in the body that produce hormones, which are essential for cell communication and various bodily functions. Endocrine disruptors are chemicals that interfere with the normal functioning of the endocrine system. Fragrances, particularly synthetic fragrances, have been identified as a source of endocrine-disrupting chemicals (EDCs). EDCs can have significant health impacts, including cancer, hormone disruption, and reproductive problems.
Phthalates, for example, are a common fragrance ingredient that has been linked to fertility issues in males and early onset puberty in females, which is associated with an increased risk of breast cancer later in life. In addition, phthalate exposure can increase the risk of asthma in both sexes. Synthetic musks, such as galaxolide and tonalide, are also commonly used in fragrances and have been linked to hormone disruption. These synthetic musks can accumulate in the body and have been detected in blood and breast milk.
A study by the Breast Cancer Prevention Partners found that a woman's risk of breast cancer has increased by more than 40% over the last two decades, with a lifetime risk of 1 in 8. Mounting studies show links between chemicals in everyday products and breast cancer. Several fragrance chemicals, such as benzene and 1,4-dioxane, have been specifically associated with mammary tumors in laboratory studies.

Allergies and allergic reactions
Fragrances can cause allergies and allergic reactions, with symptoms ranging from mild to severe. A fragrance allergy is a chronic condition where the body has an abnormal immune reaction to ordinarily harmless substances in fragranced products.
Perfume or fragrance allergies occur when an individual is exposed to a perfume that contains an allergen, causing an allergic reaction. According to a 2009 survey on fragrance sensitivity, about 30% of the population of the United States experienced irritation from a perfume, with 19% of participants reporting health effects from fragrances. Fragrance allergies typically affect the skin, with symptoms such as itchy, red rashes called allergic contact dermatitis (ACD). This can be treated with medication prescribed by a doctor or allergist. Other skin symptoms include hyperpigmentation, especially in individuals with darker skin, and in severe cases, blistering and skin peeling that can mimic burns.
In addition to skin symptoms, fragrance allergies can also cause respiratory difficulties, including coughing, shortness of breath, congestion, and a runny or stuffy nose. In rare cases, an individual may develop anaphylaxis, a severe allergic reaction that can be life-threatening. It is important to seek immediate medical attention if one experiences signs of anaphylaxis or has difficulty breathing.
Fragrance sensitivity is another condition that can occur, which is different from a true allergy as it does not involve a whole-body immune response. Instead, it refers to irritation of the airways and eyes by certain components of a fragrance. Symptoms of fragrance sensitivity include sneezing, coughing, and itchy eyes, and it can be triggered by a variety of scents such as perfumes, flowers, incense, and cigarette smoke. While fragrance sensitivity is not a true allergy, it can still cause significant discomfort and trigger allergic responses or asthma attacks in some individuals.
Identifying the specific fragrance or component causing an allergy or sensitivity can be challenging. Patch testing, which involves placing allergens on the skin for 48 hours, can be used to determine whether a substance is causing allergic contact dermatitis. However, it is important to note that fragrance allergies and sensitivities are often disruptive, especially when living or working with individuals who wear fragrances regularly. Limiting exposure, seeking treatment, and communicating one's symptoms to those around them can help manage the condition.

Self-regulation in the fragrance industry
The fragrance industry is self-regulated, meaning that safety testing does not need to be confirmed by regulators before products are sold to consumers. The current system for fragrance safety is run by the industry's own International Fragrance Association (IFRA) and their research arm, the Research Institute for Fragrance Materials (RIFM).
This self-regulation has been criticised for being a failure. A report by the national women's health non-profit, Women’s Voices for the Earth (WVE), exposes the shortcomings of the industry’s self-regulated safety program. The report's author, Alexandra Scranton, states that "the safety of fragrance chemicals is not determined, monitored or safe-guarded by any governmental agency globally in any comprehensive fashion". She also points out that the majority of scientific studies on fragrance materials are conducted by fragrance manufacturers or the fragrance trade association's laboratories, and these studies are often not published, peer-reviewed, or publicly available. This lack of independent review raises concerns about the validity and reliability of the results.
The fragrance industry's self-regulation has also been criticised for its inadequate protection of ingredient information. Manufacturers are not required to list fragrance ingredients on product labels, instead grouping them under umbrella terms such as "fragrance" or "perfume". This lack of transparency makes it difficult for consumers and their doctors to identify specific fragrance ingredients that may cause adverse reactions. It also hinders regulators from accessing the necessary information to address potentially harmful ingredients.
In response to these concerns, there have been efforts to implement new regulations and increase oversight. For example, the European Commission banned the use of certain molecules in perfumery in 2017 due to potential health risks, and the IFRA imposed a larger-than-usual number of bans and restrictions on ingredients in 2020. Additionally, a new federal law in the US requires some fragrance allergens to be disclosed on cosmetic labels, although these regulations will not be in effect until at least 2025.

Undisclosed toxic ingredients
The cosmetics industry has kept fragrance ingredients undisclosed, even those that can have potential health risks or build up in people's bodies. Manufacturers are not required to list fragrance ingredients on the product label, and often, only the word "fragrance" is used on the label, which can hide a cocktail of more than 100 toxic ingredients. These chemicals are considered trade secrets, and companies are allowed to withhold them.
The Environmental Working Group (EWG) analysed data and reported that the average fragrance product tested contained 14 secret chemicals not listed on the label. These undisclosed ingredients include chemicals associated with hormone disruption and allergic reactions and many substances that have not been assessed for safety in personal care products. For example, diethyl phthalate, a chemical found in 97% of Americans, is linked to sperm damage. Musk ketone is another example, which concentrates in human fat tissue and breast milk.
In 2011, the International Fragrance Association (IFRA) published a list of 2,339 possible fragrance materials used by its affiliated members. The list includes chemicals listed as carcinogens, such as pyridine, benzophenone, methyleugenol, and styrene. However, this list is not comprehensive, and the true number of fragrance chemicals in use today is estimated to be more than 3,500.
The lack of transparency in the fragrance industry makes it challenging for consumers to make informed decisions about the products they purchase. It also hinders researchers and regulators from fully understanding the potential health and environmental risks associated with fragrance chemicals.
