Cologne's Dark Side: Is It Dangerous?

Cologne and perfume are scented products that are widely used and loved, but are they safe? The fragrance industry is largely self-regulated, and fragrance formulas are protected under trade secret laws, so it can be hard to know exactly what's in these products. However, studies have found that many fragrances contain dozens of potentially hazardous synthetic chemicals, which can cause mild allergic reactions like headaches, sinus inflammation, itchiness, and a runny nose, and may even contribute to more serious issues such as hormonal imbalances, organ damage, and cancer. With this in mind, is cologne dangerous?

Cologne can cause allergic reactions

While cologne can be a pleasant accessory, it can also be a source of potential health hazards, particularly when it comes to allergic reactions. The use of cologne has been associated with a range of allergic responses, from mild to more severe.

One of the main concerns with cologne is the presence of undisclosed chemicals. Due to trade secret laws, fragrance manufacturers are not required to disclose all the ingredients used in their products, often hiding them under the term "fragrance" or "parfum". This lack of transparency makes it difficult for consumers to know exactly what they are exposing themselves to. According to Dr. Heather Patisaul, a biologist at North Carolina State University, any ingredient that gives cologne its odour is likely to be an allergen.

The Environmental Working Group (EWG) has reported that, in addition to trace amounts of natural essences, colognes typically contain a dozen or more potentially hazardous synthetic chemicals, some of which are derived from petroleum. These chemicals can include phthalates, which are known to disrupt hormones, including testosterone, and have been linked to developmental disorders, particularly in newborn boys.

The EWG also found that the average fragrance product tested contained 14 secret chemicals not listed on the label, including chemicals associated with hormone disruption and allergic reactions. Some of these undisclosed ingredients are chemicals with hazardous properties or a propensity to accumulate in human tissues. For example, diethyl phthalate (DEP), found in 97% of Americans, has been linked to sperm damage, while musk ketone concentrates in human fat tissue and breast milk.

Other common ingredients in cologne that can cause allergic reactions include benzaldehyde, a known narcotic, lung and eye irritant that causes nausea and abdominal pain; benzyl acetate, a known carcinogen that causes eye and lung irritation and coughing; and camphor, which can lead to dizziness, confusion, nausea, and muscle twitching.

The impact of cologne on allergic reactions is not limited to the individual wearing it. Many people suffer from allergic reactions to cologne even when it is worn by someone else, including symptoms such as sneezing, wheezing, rashes, and headaches.

To protect yourself from potential allergic reactions to cologne, it is recommended to opt for unscented cosmetics or natural alternatives that use essential oils for fragrance. Additionally, resources like Skin Deep, a product safety database run by the EWG, can help you check the safety of specific ingredients and products.

Some cologne ingredients are linked to cancer

The fragrance industry is largely self-regulated, and fragrance formulations are considered a "trade secret", so consumers cannot rely on labels to know what hazards may be present in cologne. The Environmental Working Group (EWG) reports that while many colognes contain trace amounts of natural essences, they also typically contain a dozen or more potentially hazardous synthetic chemicals, some of which are derived from petroleum.

The Campaign for Safe Cosmetics, a coalition of over 100 groups seeking transparency about chemicals in cosmetics, commissioned independent laboratory tests that revealed 38 secret chemicals in 17 leading fragrances. The average fragrance product tested contained 14 secret chemicals not listed on the label, including chemicals associated with hormone disruption and allergic reactions, and many substances that have not been assessed for safety in personal care products.

Some of the undisclosed ingredients are chemicals with hazardous properties or with a propensity to accumulate in human tissues. Examples include diethyl phthalate (DEP), a chemical found in 97% of Americans and linked to sperm damage in human epidemiological studies, and musk ketone, which concentrates in human fat tissue and breast milk.

Numerous studies have found that the most commonly used ingredients in commercial fragrance products can induce mild allergic reactions like headaches, sinus inflammation, itchiness, and a runny nose, and can contribute to worse issues such as hormonal imbalances, organ damage, and even cancer.

In 1991, the EPA tested conventional synthetic perfumes and found a long list of toxic chemical ingredients, including benzaldehyde, a known narcotic, lung and eye irritant that causes nausea, abdominal pain, and kidney damage; benzyl acetate, a known carcinogen that causes eye and lung irritation as well as coughing; and methylene chloride, which has been banned by the FDA due to severe toxic effects but is still found in labels listing "fragrance".

Cologne may contain hormone disruptors

The dangers of cologne are often overlooked, and the potential risks of using these products are not widely discussed. One of the most pressing concerns is the presence of hormone disruptors in colognes and other fragranced products.

Hormone disruptors, also known as endocrine disruptors, have the ability to interfere with the body's natural hormones and their functions. These chemicals can mimic human hormones, and even tiny doses can have significant effects on the body. They can cause a range of issues, from hormonal imbalances to reproductive and developmental problems.

One of the most common hormone disruptors found in colognes is diethyl phthalate (DEP). This chemical is often used to help suspend and evenly distribute the different elements of a fragrance. Studies have shown that DEP can disrupt hormones such as testosterone, and it is particularly concerning for pregnant women. There is evidence linking exposure to phthalates during pregnancy to developmental disorders in newborn boys. DEP has also been associated with poor lung function and various sperm issues, including reduced counts and motility.

In addition to DEP, other chemicals found in colognes can also act as hormone disruptors. For example, musk ketone, often found in cosmetics, has been detected in human fat tissue and breast milk. This chemical is a known skin irritant and hormone disruptor.

The presence of these hormone-disrupting chemicals in colognes is a cause for concern, especially considering the potential long-term effects on health. The cumulative impact of exposure to these chemicals over time is still not fully understood, and more research is needed to determine safe thresholds for exposure.

To protect yourself, it is important to be aware of the ingredients in the products you use. However, due to trade secret laws, fragrance ingredients are often not disclosed on labels, making it challenging for consumers to make informed choices. Seeking out products with full ingredient disclosure and opting for natural, organic alternatives are recommended to reduce the risk of exposure to potentially harmful chemicals.

Cologne can be harmful to children

Furthermore, colognes contain toxic chemicals that can be harmful to children. For example, phthalates, which are often found in colognes, are known to disrupt hormones, including testosterone. This can cause developmental disorders, especially in newborn boys. Phthalates have also been linked to poor lung function and sperm issues. Exposure to phthalates during early childhood or in utero may also pose risks to children's respiratory health.

In addition, the fragrance industry is largely self-regulated, and fragrance formulations are considered trade secrets. This means that manufacturers are not required to list all the ingredients on the labels, and consumers cannot be sure of what chemicals are in the products they are using. Many colognes contain dozens of potentially hazardous synthetic chemicals, and some of these chemicals have been linked to serious health issues, including cancer.

To protect children from the potential harms of cologne, it is important to keep cologne out of their reach and supervise them when they are using any fragranced products. It is also recommended to choose products with recognisable, natural ingredients and to avoid products with the ingredient "fragrance" or "perfume" on the label.

Cologne may cause respiratory issues

Cologne and other fragrance products can contain a large number of potentially hazardous synthetic chemicals, some of which are derived from petroleum. While cologne can smell intoxicating, it may also be toxic.

About 35% of people report migraines or respiratory problems due to fragrance exposure. Cologne can contain respiratory sensitizers that trigger wheezing or asthma. Some of the chemicals in cologne can also be dangerous if they build up in the body over time.

One of the most common toxic ingredients in cologne is diethyl phthalate (DEP), which has been linked to poor lung function and issues with sperm, including lower counts and reduced motility. Phthalates are used in cologne to keep all the liquid's different elements suspended and evenly distributed. However, they are also known to be endocrine disruptors, which can cause hormonal imbalances.

Another common ingredient in cologne is benzaldehyde, which is a known narcotic, lung and eye irritant. It can cause nausea, abdominal pain, and kidney damage.

If you are experiencing respiratory issues due to cologne, it is best to avoid commercial personal care products from big-box stores and opt for natural alternatives. Look for products that contain recognizable, natural ingredients and are scented with organic essential oils.
