Colognes And Cancer: A Fragrant Danger?

There are thousands of chemicals used in the fragrance industry to create scents for personal care products, cleaning products, perfumes, and home care products. While some of these chemicals are linked to cancer, birth defects, hormone disruption, and other chronic health problems, the levels of these chemicals in perfumes are typically too low to cause adverse health effects.

The fragrance industry is largely self-regulated, and fragrance formulations are considered trade secrets, so consumers won't find these chemicals listed on a product label. However, experts say that exposure to large amounts of perfume would be needed to cause any health problems.

The concentration of cologne required to cause cancer

While cologne and other fragranced products have been found to contain some carcinogenic chemicals, the concentration of these chemicals is not high enough to cause cancer in humans.

According to Cancer Council Australia, there is no evidence linking the use of fragranced products to an increased risk of cancer in humans. Similarly, Cancer Research UK has stated that while some fragrance ingredients have been shown to cause cancer in laboratory animals, this has only occurred at concentrations far higher than those found in consumer products.

In fact, experts say that exposure to large amounts of perfume would be needed to cause any health problems. Professor Ian Olver, an oncologist and cancer researcher at the University of Adelaide, explains that for some chemicals, one would need to bathe in them for long periods or ingest them to be at risk. Dr Ian Musgrave, a molecular pharmacologist at the same university, echoes this sentiment, stating that people would need to bathe in or drink perfume to become ill.

Furthermore, the European Commission's Scientific Committee on Consumer Products has calculated that the safety margin between the amount of phthalates people are exposed to via perfumes and any adverse effect is around a thousandfold. This means that the concentration of cologne required to cause cancer is far beyond what a person would typically be exposed to through normal use.

While it is important to be aware of the potential risks associated with any product, it is clear that the concentration of cologne required to cause cancer is not a realistic concern for consumers.

The presence of carcinogens in cologne

Colognes and perfumes are widely used cosmetic products, often containing a complex mixture of chemicals. While these products enhance our scent, they can also have unintended side effects on our health. One of the most pressing concerns is the presence of carcinogens—substances that can cause cancer.

The fragrance industry is largely self-regulated, and fragrance formulations are considered trade secrets, so specific chemicals are often not disclosed on labels. This makes it challenging to identify the exact chemicals present in colognes. However, studies have detected various contaminants in aromatic products, including phthalates, aldehydes, parabens, and aluminum-based salts.

Phthalates, for example, are known endocrine disruptors. They can interfere with hormones in the body and have been linked to reproductive disorders, particularly in males. Parabens, on the other hand, have been found in human breast tumors, raising concerns about their role in increasing the incidence of breast cancer.

Additionally, some fragrance chemicals are listed as carcinogens by California's Prop. 65 Program and the National Toxicology Program (NTP). Styrene, a chemical used in producing fragrances, has been confirmed by an expert panel convened by the National Academy of Sciences as a substance "reasonably anticipated to be a human carcinogen."

It's important to note that the concentration of these chemicals in colognes is typically very low and may not pose a significant risk to human health. Experts suggest that exposure to large amounts of these substances would be necessary to cause adverse health effects. However, the cumulative effect of using multiple fragranced products and long-term exposure may be a concern.

While the presence of carcinogens in colognes is a valid concern, more research is needed to definitively conclude the level of risk they pose to human health.

The effects of cologne on children

Colognes and perfumes are often very attractive to children due to their pleasant smell and ornate bottles. However, it is important for parents and guardians to be aware of the potential risks associated with their use by children.

Alcohol Poisoning

The primary concern with children and colognes is the risk of alcohol poisoning. Most colognes contain ethanol, the same type of alcohol found in alcoholic beverages, which can cause serious effects in children, including drowsiness, inebriation, and dangerously low blood sugar levels. In some cases, colognes may also contain more dangerous "toxic alcohols", further elevating the risk of poisoning. It is important to keep colognes and perfumes out of the reach of children and to avoid applying them in front of young children.

Skin Irritation

Colognes and perfumes can also cause skin irritation, particularly in children with sensitive skin. Symptoms can include itching, redness, rashes, and even blisters. According to the American Academy of Dermatology, fragrance products are the leading cause of cosmetic-related contact dermatitis. If skin irritation occurs, it is recommended to wash the affected area with soap and water and discontinue use. If the irritation persists, a topical steroid cream can be applied.

Allergic Reactions and Respiratory Issues

Fragrances can also trigger allergic reactions in susceptible children, causing symptoms such as sneezing, runny nose, itchy eyes, and skin rashes. In severe cases, they can even lead to anaphylaxis, a life-threatening allergic reaction. For children with asthma, colognes and perfumes can trigger respiratory issues such as coughing, wheezing, and shortness of breath.

Headaches and Dizziness

Overuse of fragrances or exposure to strong scents can lead to headaches, dizziness, and nausea in children.

Behavioural Issues

In some cases, fragrances can have an impact on children's behaviour, causing overstimulation or agitation, which may result in difficulty concentrating or even behavioural outbursts.

Sensory Development

Introducing children to different fragrances can help them build their sensory processing skills and improve their sense of smell. This can be particularly beneficial for children who are sensitive to smells or have difficulty with sensory processing.

Parental Advice

To minimise the risk of adverse effects, parents and guardians should choose mild, natural fragrances for their children and ensure that fragrances are used in moderation. It is also important to patch test new fragrances and be mindful of any potential sensitivities or allergies. Additionally, parents should ensure that their children do not apply fragrances without supervision and that fragrances are stored out of the reach of young children.

Overall

While fragrances can be a fun and creative way for children to express their individuality, it is crucial to prioritise their safety and well-being when considering their use.

The effects of cologne on women

While choosing a fragrance is a personal choice, it also has an impact on those nearby. Women are more likely to be attracted to men who smell different from them, as it's a way for nature to ensure the gene pool stays diverse.

According to a study by a group of researchers in Europe, women are more driven by scent when selecting a potential partner than men. The research showed that men are visual, whereas women rate olfactory cues as more important in mate choice. Women also valued olfactory cues more than men in non-sexual contexts.

In a similar study, women rated perfumed jars (vs plain body odour jars) as more attractive and pleasant. However, this effect differed according to the individual. In other words, the perfume enhanced the body odour of some men more than others.

In another study, women were more likely to say yes to finding perfume arousing during non-sexual activity than men.

When it comes to the kind of cologne women prefer, they seem to like unisex fragrances on men, as long as they don't smell too much like a woman's perfume. They also like slightly floral, fresh, and athletic scents.

Women are more likely to be exposed to fragrance in beauty, cleaning, and home care industries, as well as through personal care products.

The regulation of the fragrance industry

The fragrance industry is largely self-regulated. The International Fragrance Association (IFRA) is the industry's self-regulatory body, and it has developed the IFRA Standards to manage the safe use of fragrance. 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.

However, the regulatory history of fragrance ingredients, particularly in the United States, has been characterised by a lack of government oversight and a reliance on industry self-regulation. In the US, neither the Food and Drug Administration (FDA) nor the Environmental Protection Agency (EPA) has direct authority to monitor or require safety testing for fragrances used in cleaning products or cosmetics. Instead, the International Fragrance Research Association (IFRA), an industry trade group, sets standards for fragrance manufacturers and facilitates safety reviews of fragrance ingredients. IFRA publishes a Code of Practice, which is a set of voluntary standards for manufacturers.

There is an inherent conflict of interest when a trade group funded by the industry holds responsibility for regulating itself. For example, the headquarters of IFRA in Geneva, Switzerland, is located at the same address as the head office of Givaudan, a global fragrance manufacturer with the largest international market share.

While IFRA coordinates an independent expert panel of dermatologists, toxicologists, and environmental scientists called REXPAN, which is responsible for conducting safety assessments of fragrance ingredients, the assessments are not entirely transparent. A large proportion of the data on which the conclusions are based is unpublished research provided by the manufacturers themselves, and this data is not peer-reviewed nor made available for public scrutiny.

In contrast, the European Commission has taken a more active role in regulating the fragrance industry. In 2017, it banned the use of three molecules in perfumery due to concerns about potential skin irritation. The International Fragrance Association (IFRA) has also imposed a larger-than-usual number of bans, restrictions, and specifications on ingredients, with implementation required by early May 2022 for new creations and by May 10, 2023, for existing perfumes.

Despite these efforts, the fragrance industry continues to face criticism for its lack of transparency and the potential impact of its products on human health. Full information on the ingredients in fragrances is often kept secret from consumers, and even "natural" fragrances may contain constituents with harmful health effects, including endocrine disruptors, carcinogens, and allergens.
