Fragrance: The Hidden Health Hazard In Your Home

Fragrances are often associated with positive emotions and sensory experiences. However, the hidden chemicals behind the appealing scents may be doing more harm than good. Fragrances are made up of a mix of over 3500 chemicals, and exposure to some of these substances can lead to a wide range of health issues. From skin irritation to more severe problems like cancer, endocrine disruption, and respiratory issues, the potential dangers of fragrances are far-reaching.

The clean beauty movement has shed light on the presence of toxic ingredients in cosmetics and personal care products, but fragrances are often overlooked. With their potential to cause harm, it is important to be aware of the risks associated with fragrances and take steps to minimise exposure, especially for those with sensitive skin or pre-existing health conditions.

Fragrances are linked to health risks

Fragrances are added to a wide range of products, from detergents and soaps to cosmetics and sunscreens. While they can boost your mood and enrich your skincare experience, fragrances can also be harmful to your health.

Skin Irritation

Fragrances are the leading cause of allergic reactions on the skin. They can cause redness, itchiness, hives, rashes, and other types of dermatitis. People with sensitive skin or inflammatory skin conditions like eczema and psoriasis are particularly susceptible to these reactions. Even natural fragrances, such as essential oils, can irritate the skin if overused or used at too high an intensity.

Respiratory Issues

Fragrances can also affect the respiratory system, triggering asthma symptoms and causing allergic and non-allergic asthma. About 35% of people report experiencing migraines or respiratory problems due to fragrances.

Neurological Problems

Neurological issues such as migraines, nausea, dizziness, and mental confusion have also been linked to fragrances.

Eye Irritation

Fragrances can cause eye irritation, including tearing and inflammation.

Other Health Concerns

Fragrances have also been associated with more severe health issues, including endocrine disruption, cancer, reproductive issues, neurological problems, and allergies. The chemicals commonly found in fragranced products, such as phthalates, parabens, synthetic musks, and formaldehyde-releasing preservatives, are known to be harmful.

Reducing Exposure

To reduce exposure to these health risks, it is recommended to opt for fragrance-free or unscented products. However, it is important to note that even "unscented" products may contain masking fragrances to neutralise odours. Choosing natural fragrances or essential oils may be a safer alternative, but it is still important to patch test new products, especially for those with sensitive skin.

Fragrance chemicals are bad for the environment

One significant issue with synthetic fragrances is their lack of transparency. The exact chemical composition of these fragrances is often kept secret or listed in overly complicated chemical names, making it challenging for consumers to know what they are exposing themselves and the environment to.

These fragrance chemicals can have detrimental effects on the environment. When released into the air, they break down into other compounds, forming ozone pollution and fine particulates. This contributes to air pollution and can have serious implications for both the environment and human health.

Additionally, the improper disposal of products containing fragrance chemicals can lead to water contamination. These chemicals can leach into soil and water systems, harming wildlife and disrupting ecosystems. Some fragrance compounds, such as musk, accumulate in the environment and bioaccumulate up the food chain. They can attach themselves to the fatty tissue of aquatic organisms, and wastewater treatment does not effectively remove these substances, leading to potential harm to aquatic life and the ecosystems that depend on them.

Furthermore, phosphates present in some fragrance mixtures can cause algae blooms in waterways, depleting oxygen levels. Other chemicals can reduce the surface tension of water, making it easier for pesticides and other toxins to enter the water and be absorbed by plants and animals.

Overall, the use of fragrance chemicals has significant environmental impacts, contributing to air and water pollution and posing risks to various forms of life.

Fragrances are highly toxic

The problem with fragrances lies in the synthetic chemicals they contain, which are derived from petroleum and tar. These chemicals include acetone, phenol, toluene, benzyl acetate, and limonene. Out of the 4,000 chemicals used as fragrances, only 800 have been tested for toxicity, and these toxins can cause central nervous system damage. Physical reactions to fragrances are varied and include respiratory issues, neurological problems, skin irritation, and eye inflammation. Fragrances are also linked to skin allergies and sensitivity, with 30% of all allergic reactions being caused by fragrances.

The toxins in fragrances create a bubble of harmful chemicals that continues to be emitted for hours after use, affecting everyone nearby. This is particularly problematic for people with asthma, with studies finding that exposure to perfumes and colognes triggered reactions in three out of four asthmatics. Fragrances may also contribute to the development of asthma in children.

The U.S. FDA acknowledges that fragrances are responsible for a significant proportion of allergic reactions, yet manufacturers of fragranced products are protected under the provision of "trade secrets", allowing them to add ingredients without disclosing them to consumers. This lack of transparency makes it difficult for consumers to make informed choices and avoid potential health risks associated with fragrance use.

To reduce exposure to toxic fragrances, it is recommended to opt for fragrance-free products or those with natural fragrances derived from essential oils. However, even natural fragrances can cause adverse reactions in some individuals, so patch testing is recommended before incorporating any new fragranced product into your routine.

Fragrance chemicals can pass from the skin into the blood

The skin is the largest organ in the human body and has three layers: the epidermis, dermis, and subcutaneous fat. While these layers act as a protective barrier, substances can still be absorbed if they are small enough.

The amount of a product or chemical absorbed by the skin depends on several factors, including chemical size, skin temperature, skin integrity, chemical concentration, exposure length, and the area of skin exposed.

Fragrance chemicals, like other toxic chemicals, can pass from the skin and into the blood. Fragrances often contain phthalates, which are endocrine disruptors that can act like hormones in the human body and cause a host of health problems, including cancer, reproductive and developmental toxicity, endocrine disruption, birth defects, respiratory problems, and lower sperm counts in men.

The fragrance industry is self-regulated, meaning safety testing is not required before products are sold to consumers. Manufacturers are not required to list fragrance ingredients on product labels, and the word "fragrance" can hide a cocktail of more than 100 toxic ingredients.

To avoid exposure to potentially harmful fragrance chemicals, the Environmental Working Group advises consumers to choose fragrance-free products and be cautious of products labeled as "natural fragrance," "fragrance-free," or "unscented," as these may still contain masking fragrances to cover up unpleasant chemical smells.

Fragrances can cause skin allergies

Fragrances are linked to a wide range of health issues, including skin allergies. According to Martin A. Smith, MD, a double-board certified allergist and immunologist, fragrance is the main culprit for the rise in skin allergies and sensitive skin. He states that if he asks patients with eczema, sensitive skin, or psoriasis to avoid one ingredient, it is always fragrance.

Fragrances commonly cause allergic reactions on the skin because they undergo a chemical change when they come into contact with it. They also cause non-eczematous contact reactions, irritation, and photosensitivity (a rash that occurs after sun exposure). Dr. Smith adds that most people who react adversely to fragrance experience redness, tingling, burning, or itching. However, more severe cases can cause the skin to become extremely itchy, raised, and even weepy. These reactions can also lead to a compromised skin barrier.

The compounds that make up fragrances are usually sourced from a variety of origins, like plants. One such group of compounds is terpenes. Terpenes, in low concentrations, are usually not harmful to human health. However, their reaction with ozone and the hydroxyl radical can generate secondary pollutants such as formaldehyde and ultrafine particles, which can persist in indoor air and be harmful.

Fragrance chemicals are not just harmful to human health but also to the environment. A study has linked the chemical vapours in fragrances, known as volatile organic compounds, to ozone pollution and the formation of fine particulates.
