Fragrance And Cancer: Is There A Link?

Fragrances are used in a wide range of everyday products, from perfumes and cosmetics to cleaning products and laundry detergents. They are made up of dozens, sometimes hundreds, of different chemicals, some of which have been linked to adverse health effects, including cancer. While some of these chemicals are safe, others have never been tested for safety, and certain fragrance ingredients have been shown to cause cancer in laboratory animals.

The potential health risks of fragrances have sparked concerns and debates, with regulatory bodies and expert panels worldwide evaluating and assessing the safety of these chemicals. The complex mixture of ingredients in fragrances and the lack of transparent labelling make it challenging for consumers to make informed choices.

Fragrance ingredients linked to cancer

Fragrances are made up of dozens, sometimes hundreds, of different chemicals. While some of these chemicals are safe, others have never been tested for safety, and some are even known to cause cancer.

According to the Breast Cancer Prevention Partners (BCPP), 1 out of every 4 fragrance ingredients detected in their tests was linked to cancer. Some of the harmful fragrance chemicals they found include beta-myrcene, diethyl phthalate (DEP), benzophenone, and propylene glycol.

The International Fragrance Association (IFRA) estimates that there are approximately 4,000 fragrance ingredients used to create the scents in personal care products, cosmetics, cleaning products, and fine fragrances. Some of these ingredients, such as benzophenone, methyleugenol, and styrene, are listed as carcinogens by California's Prop. 65 Program and the National Toxicology Program (NTP).

Styrene, in particular, has been identified as a human carcinogen by the National Academy of Sciences and the National Toxicology Program. It is often used as an ingredient in fragrances added to a wide variety of consumer products, including cologne and other personal care products, as well as household care products such as dish and laundry detergent.

Phthalates, aldehydes, parabens, and aluminum-based salts are also common contaminants in aromatic products that have been linked to various health issues, including allergies, breast cancer, and reproductive disorders.

While regulatory bodies and expert panels around the world evaluate and assess the safety of fragrance ingredients, it is important to note that not all ingredients are required to be listed on product labels, making it difficult for consumers to know exactly what they are exposing themselves to.

Fragrance chemicals in everyday products

Fragrances are found in a wide range of everyday products, including perfumes, cosmetics, and bath and shower products. There are over 3,000 individual fragrance ingredients used in our favorite perfumes, body lotions, hair products, makeup, and baby products, to name a few.

While some of these chemicals are safe for our health and the environment, others have never been tested for safety. According to scientists, some of these chemicals are even known to cause cancer, hormone disruption, and reproductive harm.

The fact that it’s even legal for companies to use fragrances with known human carcinogens in personal care, beauty, and cleaning products is mind-blowing. We use body wash, shampoo, moisturizer, sunscreen, and deodorant every day or even multiple times a day. Over the long term, your exposure to all these chemicals adds up and can put your health at risk.

In 2011, the National Academy of Sciences confirmed a federal interagency group's conclusion that styrene, a chemical building block used to produce a wide variety of everyday products, can cause cancer. The committee found "compelling evidence" for that conclusion. Moreover, it said that some studies would support "a strong argument" for listing styrene as a known human carcinogen. That's an even more definitive label – signaling a dangerous substance that should be strictly controlled.

It is important to note that not all fragrance chemicals are harmful. Many essential oils, for example, have been shown to have positive health effects, including antioxidant, antimicrobial, and antitumor activities. However, it is always a good idea to check the labels of products and choose fragrance-free or products from companies that are fully transparent about their fragrance ingredients.

Toxic chemicals in fragrances

The use of toxic chemicals in fragrances is a cause for concern, with an array of harmful effects on human health. The term "fragrance" on product labels can hide a cocktail of toxic ingredients, with manufacturers taking advantage of trade secret protections to avoid disclosing specific chemicals used. These toxic ingredients can cause a range of issues, from mild allergic reactions to more severe problems like cancer.

Phthalates are a common ingredient in fragrances, acting as endocrine disruptors. They have been linked to reduced IQ in children, sperm damage in men, and obesity. Another ingredient, musk ketone, is a skin and hormone disruptor and a possible carcinogen. Benzaldehyde is a narcotic and lung and eye irritant, causing nausea, abdominal pain, and kidney damage. Benzyl acetate is a known carcinogen, causing eye and lung irritation, and coughing. Camphor can cause dizziness, confusion, nausea, and muscle twitching. Ethyl acetate can irritate the eyes and respiratory system, while limonene and linalool are also known carcinogens.

The use of these toxic chemicals in fragrances poses a serious health risk, and consumers are often unaware of their presence due to inadequate labelling laws.

Fragrance safety evaluations

Fragrance safety is a complex and evolving area of research, with ongoing evaluations conducted by regulatory bodies and expert panels worldwide. The potential health risks associated with fragrances have sparked concerns, warranting investigations into their safety. Here is an overview of the key aspects of fragrance safety evaluations:

The Complexity of Fragrance Chemicals

Fragrances are composed of a diverse array of chemicals, with approximately 3,000 to 4,000 individual ingredients used in various products. These chemicals are often referred to as "fragrance" or "parfum" on product labels, obscuring the specific chemicals within. This lack of transparency makes it challenging for consumers to make informed choices.

Health Concerns and Links to Cancer

Numerous studies have linked certain fragrance chemicals to adverse health effects. Some of the most common health concerns associated with fragrances include cancer, hormone disruption, reproductive harm, respiratory issues, allergies, and endocrine disruption. Specific chemicals like phthalates, parabens, aldehydes, and aluminum-based salts have been implicated in these health issues.

Regulatory Efforts and Standardization

Regulatory bodies play a crucial role in evaluating and regulating fragrance safety. For example, the International Fragrance Association (IFRA) provides a palette of approximately 4,000 fragrance ingredients for perfumers to work with. Additionally, organizations like the Research Institute for Fragrance Materials Expert Panel continuously assess the safety of fragrance ingredients. When hazardous ingredients are identified, the IFRA issues standards to restrict or prohibit their use.

Country-Specific Regulations

Fragrance safety regulations vary across countries. For instance, in Australia, fragrance ingredients are regulated by the National Industrial Chemicals Notification and Assessment Scheme. Fragrant products sold in Australia must list "fragrance" or "perfume" on the label, but individual ingredients are not required to be disclosed. This differs from other regions, where more stringent disclosure requirements may be in place.

Laboratory Testing and Safety Assessments

Laboratory testing plays a pivotal role in fragrance safety evaluations. Chemical safety evaluations consider the intended use of a chemical, its concentration, and potential short-term and long-term effects. These evaluations involve studies using low, medium, and high doses to comprehensively understand the potential risks associated with exposure.

The Role of Consumer Advocacy

Consumer advocacy groups have been instrumental in pushing for safer fragrances and transparent ingredient disclosure. Campaigns for safe cosmetics and initiatives like the Safe Cosmetics and Personal Care Products Act of 2019 aim to strengthen fragrance safety regulations and protect consumers from potential health risks.

In conclusion, fragrance safety evaluations are multifaceted and constantly evolving. While fragrances can enhance our daily lives, it is crucial to approach them with caution and advocate for transparent practices and stringent safety standards to minimize potential health risks.

Fragrance ingredient transparency

The fragrance industry is a large and growing business, with the global fragrance market estimated to be worth about 92 billion U.S. dollars by 2024. Perfumers draw from an International Fragrance Association (IFRA) palette of approximately 4,000 fragrance ingredients to create the scents in personal care products, cosmetics, cleaning products, and fine fragrances.

However, there is a lack of transparency around fragrance ingredients, with brands often claiming proprietary information and trade secrets to avoid disclosing exact ingredients. This lack of transparency has raised concerns among consumers and advocacy groups, who argue that they have the right to know exactly what they are putting on their bodies.

Health Concerns

The potential health risks associated with fragrance ingredients have been a significant driver for the push for greater transparency. According to the Breast Cancer Prevention Partners (BCPP), many fragrance chemicals are linked to cancer, birth defects, hormone disruption, and other chronic health problems. In their 2018 report, BCPP found 338 fragrance chemicals in the 25 personal care products tested, with 99 of those chemicals linked to at least one health concern.

Additionally, a 2021 paper on the hazards of fragrances in consumer products stated that they can cause "detrimental health or environmental effects including contact dermatitis, photosensitivity, photo-allergy, and immediate contact reactions, which can negatively impact the quality of life."

Regulatory Landscape

The regulatory landscape for fragrance ingredients varies across regions. In the United States, there is currently no requirement for companies to disclose fragrance ingredients, and voluntary disclosure measures have been inadequate. However, due to the Modernisation of Cosmetics Regulation Act 2022 (MoCRA), some fragrance allergens will have to be listed in the future, although the rule has been delayed.

In the European Union, only 26 of the 3,000-plus fragrance ingredients must be specifically listed as they are defined as allergens. This number will increase to 81 in 2026 for new products and 2028 for existing products, but it is still considered insufficient by advocacy groups.

Industry Response

Despite the lack of mandatory regulations in some regions, some companies have taken steps towards greater fragrance ingredient transparency. Large multinationals like Unilever, Procter & Gamble, and Johnson & Johnson have announced fragrance ingredient disclosure policies, providing multiple ways for consumers to access ingredient information.

Additionally, smaller "safe cosmetics companies" have been voluntarily disclosing their fragrance ingredients, including California Baby, Intelligent Nutrients, Aubrey Organics, and others. These companies recognize that disclosing in-depth product and ingredient information builds brand trust and helps consumers make informed purchasing decisions.

However, not all companies have been as transparent. L'Oréal, for example, has made vague announcements about fragrance ingredient disclosure without providing specifics on where, when, and how that disclosure would take place.

Moving Forward

While there have been some positive steps towards fragrance ingredient transparency, there is still much room for improvement. Advocacy groups and consumers continue to call for full fragrance ingredient disclosure to make safer, more informed purchases.

Voluntary disclosure measures by companies are a step in the right direction, but mandatory regulations are needed to ensure consistent and comprehensive transparency across the industry. As consumers become increasingly conscious of the products they use, companies that prioritize transparency and sustainability will likely gain trust and loyalty from their customers.
