Fragrance Allergens: Understanding The Hidden Scents That Cause Reactions

Fragrance allergens are substances that can cause allergic reactions when they come into contact with the skin or are inhaled. They are found in perfumes and colognes, as well as scented products like candles, detergents, fabric softeners, and other household products. Fragrance allergies are less common than seasonal allergies, but they affect enough people that many public spaces advertise themselves as fragrance-free. Fragrance allergens can be synthetic or natural, and they can cause reactions ranging from mild contact dermatitis to severe respiratory issues and asthma.

Fragrance allergens can be natural or synthetic

Fragrance allergens are substances that can cause an allergic reaction when they come into contact with the skin or are inhaled. They are found in perfumes and colognes, as well as scented products like candles, and even household products like laundry detergents and fabric softeners. These allergens can be natural or synthetic.

Natural fragrance allergens are found in essential oils and plant-based fragrances, also known as "natural complex substances". For example, lavender essential oil contains about 35% linalool, a known fragrance allergen. Other natural fragrance allergens include cinnamon, nutmeg, lemon, orange, and grapefruit.

Synthetic fragrance allergens are created from synthetic chemical substances. These can also be found in perfumes and cosmetics, as well as household products. Some synthetic fragrance allergens include limonene, Lyral, and atranol.

It's important to note that while essential oils are natural, they are not necessarily safer than synthetic fragrances. Allergenic chemicals, whether natural or synthetic, have the potential to cause itching and, in rare cases, more severe reactions.

To protect consumers, regulations have been put in place in some countries to require the declaration of certain fragrance allergens on product labels. These regulations help individuals with fragrance allergies make informed choices and avoid products that may trigger an allergic reaction.

They can cause a range of reactions, from mild to severe

Fragrance allergens can cause a wide range of reactions, from mild to severe. These reactions can occur whether the fragrances are sourced from synthetic chemical substances or natural extracts like essential oils.

Mild reactions can include skin irritations such as itching and rashes. Fragrance allergies can also cause allergic contact dermatitis, which can result in scaly, itchy, and burning skin. This can be treated with topical steroids, a short course of systemic steroids, and regular use of emollients.

More severe reactions can include respiratory distress and severe respiratory issues such as asthma symptoms. Fragrance allergies can also cause allergic contact stomatitis, resulting in cheilitis, gingivitis, blisters, and erosions in the mouth.

It's important to note that fragrance allergies are less common than seasonal allergies, but they can have a significant impact on those who experience them. The frequency of fragrance allergies is decreasing due to the reduced use of oakmoss absolute as a fragrance.

To manage fragrance allergies, it is recommended to choose products labelled as "fragrance-free" or "unscented". However, it's important to be aware that these products may still contain masking fragrances or unidentified fragrances listed as "botanical", "herbal", or "natural" ingredients.

Fragrance allergies are less common than seasonal allergies

According to the American Academy of Dermatology (AAD), about 2.5 million Americans suffer from fragrance allergies, and this number is on the rise. Fragrances contain various chemicals, with an estimated 2,500 to 3,000 unique chemicals used in everyday products. These chemicals are often unlisted, as companies are not required to disclose specific ingredients, instead listing "`fragrance`" as a blanket term. This makes it challenging for those with fragrance allergies to avoid triggers.

The symptoms of fragrance allergies can vary widely, ranging from mild to severe. The skin is commonly affected, with possible rashes, redness, itchiness, and blistering. Fragrance allergies can also impact the eyes, causing redness, irritation, tearing, and swelling of the eyelids. Inhalation of fragrances can lead to sneezing, a runny nose, nasal congestion, headaches, and even breathing difficulties.

While less prevalent than seasonal allergies, fragrance allergies are a significant concern for a notable portion of the population. The impact of fragrance allergens on individuals' health and well-being underscores the importance of understanding these allergens and their potential effects.

Fragrance allergens are found in many products

Fragrance allergens are substances that can cause allergic reactions when they come into contact with the skin or are inhaled. They are found in a wide range of products, from perfumes and colognes to household items like laundry detergents and fabric softeners. These allergens can be derived from synthetic chemical substances or natural extracts like essential oils. While fragrance allergies are less common than seasonal allergies, they affect a significant number of people, with some workplaces and public spaces adopting "fragrance-free" policies to accommodate those with allergies.

Fragrance allergens are not limited to perfumes and cosmetics. They are also prevalent in personal care products such as body wash, lotions, shampoos, conditioners, deodorants, baby wipes, and sanitary pads. Additionally, household products like laundry detergents, fabric softeners, air fresheners, cleaning agents, and even toilet paper may contain fragrance allergens. These allergens can cause various reactions, ranging from mild contact dermatitis to severe respiratory issues and asthma symptoms.

The impact of fragrance allergens is significant enough that several countries have regulations in place regarding their labelling and disclosure. For example, Europe and the UK require specific fragrance allergens to be listed in the ingredient declaration if they meet a minimum amount in the product. Similarly, countries like India and New Zealand mandate the inclusion of certain fragrance allergens in ingredient declarations. These regulations aim to protect consumers, especially those with sensitivities to fragrance allergens, by providing transparent information about the product's contents.

The complexity of fragrance creation has increased due to the growing list of fragrance allergens. While it is possible to formulate fragrances without these allergens, it can impact the final product. As a result, fragrance manufacturers must carefully consider the intended use of their products to ensure compliance with regulations and guidance.

Some countries require fragrance allergens to be listed in the ingredient declaration

Fragrance allergens are substances that can cause allergic reactions when they come into contact with the skin or are inhaled. These can be found in perfumes and colognes, as well as scented products like candles, laundry detergents, and fabric softeners. Fragrance allergies can cause reactions ranging from mild contact dermatitis to severe respiratory issues and asthma symptoms.

Due to the potential for adverse reactions, some countries have implemented regulations requiring that certain fragrance allergens be listed in the ingredient declaration if they are present in a minimum amount in the product. These regulations help to protect consumers, particularly those with sensitivities to fragrance allergens, by allowing them to make informed choices and avoid potential allergens.

In Europe and the UK, there are currently 24 fragrance allergens that must be listed in the ingredient declaration if they are present at concentrations exceeding 0.01% in rinse-off products and 0.001% in leave-on products. An amendment has been proposed to add 54 additional fragrance allergens to this list, and it is expected to come into effect by July 2026 or July 2028.

Other countries with similar regulations include India, New Zealand, and South Korea, which all require the declaration of 26 fragrance allergens. The United Arab Emirates (UAE) also requires the declaration of aromatic substances in perfumes at a concentration above 0.001%.

In Canada, proposed amendments aim to align with EU regulations by requiring the labelling of 24 fragrance allergens. These regulations are expected to come into effect by April 2026.

In the United States, while there are currently no federal requirements for listing fragrance allergens, the Modernization of Cosmetics Regulation Act of 2022 (MoCRA) mandates the FDA to identify fragrance allergens for inclusion in ingredient declarations. The proposed regulations are expected to be published in October 2024.
