Colognes: Brain Cell Killers Or Just Nice Scents?

The use of cologne and perfume is widespread, with many people applying it daily. However, there are concerns about the potential health risks associated with these fragrances. While some sources suggest that cologne and perfume can cause various issues, such as respiratory problems, allergies, and skin conditions, there is also speculation about whether these products can cause brain damage. This question has sparked discussions, with some people expressing worries about the potential impact of regularly inhaling fragrances.

Artificial fragrances can cause respiratory issues

The chemicals in artificial fragrances, such as glycerol ether and monoethanolamines, irritate the human respiratory system. In addition, ethanol, which is often added to perfumes in bulk, can intensify respiratory sensitization. A research study showed that asthma patients who pre-inhaled ethanol had a higher average cough than healthy subjects.

Fragranced products emit volatile organic compounds (VOCs) that can trigger eye and respiratory tract irritation, headaches, and dizziness. These VOCs include formaldehyde, petroleum distillates, limonene, esters, and alcohols. Exposure to VOCs, even at levels below safety recommendations, can increase the risk of asthma in children.

Fragrance sensitivity is a condition where the airways are irritated by ingredients or chemicals in natural or manufactured scents. Symptoms of fragrance sensitivity include sneezing, coughing, and itchy eyes. Fragrance sensitivity can be triggered by a wide variety of organic and artificial chemicals in different scents, including perfumes and colognes.

Some colognes contain neurotoxic compounds

While it is unlikely that colognes are toxic enough to kill brain cells, some do contain neurotoxic compounds.

The human blood-brain barrier does a good job of keeping harmful substances out of the brain. However, it is important to note that many colognes and perfumes contain synthetic chemicals, with artificial fragrances being made almost exclusively from these compounds. One such chemical is Diethylphthalate (DEP), a phthalate ester and fragrance agent that has been linked to an increased risk of skin diseases and respiratory issues. Phthalates have also been identified as neurotoxins, which can be harmful to the body and brain if inhaled or ingested in large quantities.

Another potential issue with colognes and perfumes is the presence of ethanol, which is often added in large quantities to increase the volume of the product and enhance the intensity of the fragrance. Ethanol can irritate the respiratory system, particularly for individuals with asthma or allergies.

In addition, natural essential oils that form the basis of many fragrances have recently been recognised to have toxic effects. For example, b-damascenone, a compound in rose essential oils, can cause allergic reactions in large quantities, while 1,8-cineol, which gives eucalyptus its smell, can cause liver damage if consumed in vast amounts.

Overall, while the occasional exposure to cologne is unlikely to result in significant harm, it is advisable to limit prolonged or excessive exposure to these products, especially for individuals with respiratory issues or allergies.

Colognes can cause skin irritation

Perfumes and colognes can directly cause skin irritation, but they can also cause photosensitivity. One person, for example, washed their hands with scented soap and then stood in the sun. The hand that was exposed to the sun developed a minor rash, while the other hand was unaffected.

In another example, someone went to an outdoor concert with aftershave on their neck and suffered from severe irritation and sore welts.

The fragrance additives in perfume, and the nickel that’s often used in jewelry, are two of the most common triggers of allergic skin reactions on the neck.

Adverse reactions to fragrances in perfumes and in fragranced cosmetic products include allergic contact dermatitis, irritant contact dermatitis, photosensitivity, immediate contact reactions (contact urticaria), and pigmented contact dermatitis.

Perfumes and colognes can also be harmful to the respiratory system. Perfume contains numerous chemicals that will irritate the human respiratory system, such as glycerol ether and monoethanolamines, two renowned irritants.

Additionally, ethanol inside the perfume can actually intensify the sensitization of the respiratory system. A research study showed that asthma patients who pre-inhaled ethanol had a higher average cough than healthy experiment subjects did, and the allergy reaction was dose-dependent.

Colognes can cause allergic reactions

Colognes and perfumes can cause allergic reactions, and it is important to be aware of the potential risks involved in using them.

Firstly, it is worth noting that colognes and perfumes contain numerous chemicals, including glycerol ether and monoethanolamines, which are known irritants to the human respiratory system. Inhaling these substances can lead to allergic reactions, such as coughing, sneezing, and nasal congestion. The ethanol in colognes and perfumes can also intensify respiratory issues, particularly for asthma patients.

Secondly, an allergic reaction can occur through touching or inhaling cologne or perfume. Symptoms of a perfume or cologne allergy can include itching, skin rashes, blisters, and burning sensations on the skin. In more severe cases, an allergic reaction can lead to anaphylaxis, where the airways become inflamed and close up, making it difficult to breathe. This requires immediate emergency medical attention.

Furthermore, it is important to distinguish between a perfume allergy and sensitivity. An allergy occurs when the body identifies an ingredient in the perfume as a foreign substance and releases an inflammatory reaction to fight it off. On the other hand, sensitivity is a reaction to an irritant, and while it may cause similar symptoms such as rashes, they are usually milder and shorter-lasting.

To manage cologne or perfume allergies, one can opt for medications like antihistamines, topical corticosteroid creams, or oatmeal baths to soothe itching and inflammation. It is also recommended to avoid the substance causing the allergy and opt for natural, plant-based perfumes with minimal ingredients to reduce the risk of allergic reactions.

Colognes can cause liver damage

The potential for harm from colognes and perfumes is significant enough that scientists have been working for years to understand the effects of these products on human health. The results of these studies indicate that the chemicals found in colognes and perfumes, such as phthalates, aldehydes, parabens, and aluminum-based salts, can cause a range of side effects, including allergies, breast cancer, reproductive disorders, skin allergies, nervous system damage, and migraine headaches.

One of the most common contaminants found in spray products is toluene, which has been linked to liver damage. Exposure to toluene can cause fatigue, confusion, weakness, and loss of muscle coordination. It can also affect the central nervous system, causing headaches, nausea, and loss of appetite.

Other chemicals found in colognes, such as ethyl alcohol (ethanol) and isopropyl alcohol (isopropanol), can be poisonous if ingested and may cause decreased consciousness, coma, diarrhea, nausea, vomiting, seizures, and uncoordinated movement.

The potential for harm from colognes and perfumes is not limited to direct exposure through inhalation or skin contact. The chemicals in these products can also build up in the body over time, leading to long-term health issues. For example, exposure to styrene, an ingredient in many cosmetic products, has been linked to an increased risk of cancer.

To minimize the potential risks associated with colognes and perfumes, it is important to increase consumer awareness about their adverse health effects. In addition, consumers can look for products that list all their ingredients on the label, rather than using the terms "parfum" or "fragrance," which do not provide detailed information about the chemicals included in the product. Seeking out products scented with essential oils or choosing unscented products can also reduce the potential for harm.
