Fragrance allergens are found in perfumes, cosmetics, personal care products, and household items like cleaners and air fresheners. They are among the 2,500 fragrance ingredients used to give products a pleasant smell. While fragrance allergies are not dangerous, they can cause skin irritation and allergic reactions in 1-3% of the population. The fragrance industry has historically kept the ingredients a secret, but regulations are being introduced to increase transparency and consumer protection. These regulations will require brands to list fragrance allergens on product labels, helping those with allergies to avoid specific ingredients.

Fragrance allergens are found in perfumes, cosmetics, personal care products, and household products
Fragrance allergens are found in a variety of products, including perfumes, cosmetics, personal care items, and household products. These allergens can cause skin irritations and allergic reactions in some individuals. Cosmetic products such as soaps, lotions, makeup, and fragrances can trigger allergic reactions, with symptoms typically manifesting as itchy, red rashes on the skin, a condition known as contact dermatitis. Fragrances can also affect the respiratory system, particularly for those with asthma, allergic rhinitis, or viral respiratory infections. Inhalation of certain fragrances may lead to shortness of breath, coughing, a runny nose, and other respiratory symptoms.
To address this issue, regulatory efforts are being made to enhance transparency and oversight. For instance, the European Union (EU) adopted Regulation (EU) 2023/1545 in July 2023, updating the labelling of fragrance allergens under Annex III of Regulation (EC) 1223/2009 on cosmetic products. This regulation aims to improve consumer protection by mandating the disclosure of specific fragrance allergens on product labels. Similarly, Health Canada has proposed regulations for cosmetic fragrance ingredient disclosure, aiming to increase chemical transparency and improve regulatory oversight.
The Scientific Committee on Consumer Safety (SCCS) has also played a role in understanding fragrance allergens. In 2012, the SCCS released its scientific opinion, finding that 16% of eczema patients were sensitized to ingredients found in fragrances, and 1-3% of Europeans showed allergic reactions to common fragrance ingredients. To protect consumers, cosmetic regulations require the declaration of fragrance allergens on labels when present in specific concentrations. These regulations ensure that consumers are informed and can make informed choices to avoid potential allergic reactions.
To prevent allergic reactions, it is crucial to understand individual sensitivities and carefully read product ingredient labels. Terms like "hypoallergenic" or "fragrance-free" may not always be reliable, as there are no standardized definitions governing their use. By being aware of specific allergens that trigger reactions, individuals can make informed choices and minimize the risk of adverse effects. The FDA is actively researching how allergens interact with the body's immune system to better understand and identify potential allergenic ingredients in cosmetic products.

The fragrance industry keeps ingredients a secret, making allergies harder to diagnose and treat
Fragrance allergens are found in perfumes, cosmetics, personal care products, and household products like cleaners and air fresheners. They can cause skin irritation, allergies, and even more severe allergic reactions like anaphylaxis.
The fragrance industry has long kept the ingredients in their products a secret, claiming that disclosing this information would hurt their competitive edge. This secrecy makes diagnosing and treating fragrance allergies more difficult. Without knowing the specific ingredients in a product, it can be challenging for healthcare providers to identify the exact allergen causing a patient's reaction. It also makes it hard for patients to avoid the allergen, as they may not know what specific ingredient to look for on product labels.
In 2023, the European Union (EU) adopted Regulation (EU) 2023/1545, updating the labelling of fragrance allergens under Annex III to Regulation (EC) 1223/2009 on cosmetic products. This regulation expands the number of recognized allergenic substances and aims to increase consumer protection. However, it still allows manufacturers to avoid listing individual perfuming substances, instead using the terms "fragrance" or "parfum" to cover multiple ingredients.
While the fragrance industry argues that secrecy is vital to their business model, critics point out that reverse engineering of fragrances is already common, and full disclosure of ingredients would greatly benefit consumers with allergies. The International Fragrance Association (IFRA) provides some guidance on the safe use of fragrances, but ingredient labelling on fragrance products remains inconsistent and often insufficient for those with allergies.

The EU has published regulations on the labelling of allergenic fragrance substances in cosmetic products
Fragrance allergens are found in perfumes, cosmetics, personal care products, and household products like cleaners and air fresheners. They are among the more than 2,500 fragrance ingredients used in these products to give them a pleasant smell. On July 26, 2023, the European Union (EU) published the 2023/1545 Regulation on the labelling of allergenic fragrance substances in cosmetic products. This regulation came into force on August 16, 2023, and expands the number of recognized allergenic substances to 81, compared to 24 before this update.
The new regulation introduces grouped names for certain substances under the same designation, which can be found in the International Nomenclature of Cosmetic Ingredients (INCI) list of cosmetic products. For example, the grouped name "Citral" includes the substances citral, geraniol, and nerol. A cosmetic product may contain label-able allergens and not indicate them on the list of ingredients as long as they do not exceed certain thresholds. These thresholds depend on the type of product, with rinse-off products having different limitations to leave-on products.
The regulation requires brands to modify the labelling of both new and existing cosmetic products. Deadlines have been set to give brands time to comply: by July 31, 2026, only products with compliant labelling will be placed on the EU market, and existing products have until July 31, 2028, to comply. The regulation is expected to increase consumer protection, particularly for vulnerable individuals with sensitivities to fragrance allergens, by mandating the disclosure of specific fragrance allergens on product labels.
The International Fragrance Association (IFRA) is the reference organization for this subject and issues recommendations regarding the safe use of fragrances in finished products. They define maximum concentration levels for fragrances and their allergens per product category.

The International Fragrance Association (IFRA) issues recommendations on the safe use of fragrances in finished products
Fragrance allergens are found in perfumes, cosmetics, personal care products, and household products. They can cause irritation or allergic reactions in sensitive individuals, such as redness and itching. To ensure the safe use of fragrances, the International Fragrance Association (IFRA) has developed the IFRA Standards, a set of global guidelines that define safe usage and create transparency around fragrance ingredients.
The IFRA Standards are recognised by industry groups and authorities worldwide, including Cosmetics Europe and Brazilian policymakers, who have adopted them into law. The Standards are based on scientific evidence and consumer insights, banning or restricting certain ingredients to protect consumers from potential risks. They specify the maximum permitted usage levels of fragrance ingredients in different product categories, such as rinse-off and leave-on products, with the aim of keeping ingredient concentrations below levels that may cause adverse effects.
IFRA categorises its standards into three types: Prohibited, Restricted, and Specification. Prohibited Standards aim to prevent the inclusion of harmful substances in consumer products, ensuring consumer safety and well-being. Restricted Standards define the maximum permitted usage levels of specific ingredients in different product categories, based on scientific assessments and toxicological studies. Specification Standards apply to ingredients with specific chemical criteria, defining purity and composition requirements for use in fragrance formulations.
IFRA regularly notifies its members and stakeholders of new and amended Standards, ensuring compliance with regulations and timely implementation. The Standards are compulsory for all IFRA members, who produce around 80% of the global volume of fragrance. The association also collaborates with regulatory bodies worldwide to promote the safe use of fragrances and ensure sustainability.
The IFRA Code of Practice is a commitment by the global fragrance industry to ensure best practices and the safe use of fragrance ingredients and mixtures. It covers the manufacture, handling, and safety assessments of fragrance ingredients and mixtures, applying to all IFRA members worldwide. The Code of Practice is essential for maintaining trust in fragranced products and respecting the environment.

Patch testing is used to diagnose fragrance allergies
Fragrance allergens are found in perfumes, cosmetics, personal care products, and household products like cleaners and air fresheners. They are among more than 2,500 fragrance ingredients used to give products a pleasant smell. From the general population, 1-3% of Europeans show allergic reactions to common fragrance ingredients. The risks associated with fragrance allergens are irritation or allergic reactions for individuals sensitive to these substances, such as redness and itching.
Patch testing is the standard procedure used to diagnose contact allergies. It is used to evaluate the efficacy of fragrance mix (FM) as a screen for fragrance allergy. Patients are included in the study if they have had positive allergic reactions to FM, to one of the eight ingredients of FM, to one of 14 other fragrance materials, or to their own perfume. Dermatitis of the hands and face were the most common presenting complaints. Patch testing with a new fragrance mix can detect additional patients sensitive to perfumes and missed by the current fragrance mix.
In a study of 91 patients, 85 (93%) had a positive allergic patch test reaction to FM. 22 of the 40 tested to the extended fragrance series were positive to other perfumes as well, and of these, there were 14 reactions (in nine patients) to allergens not in the FM. In addition, six patients were positive only to separately tested fragrance constituents and not to the FM. Patch testing with fine fragrances can be compared with fragrance mix, balsam of Peru, and a fragrance series.
The baseline series for patch testing in consecutive patients for contact allergy screening are recommended by experts from different working groups and countries. Fragrance test preparations included in different baseline series may range from a few to more than 10 test preparations, including FM I, FM II, BOP, hydroperoxides of linalool and limonene, some essential oils, some individual ingredients of FM I and FM II, and other non-mix fragrances. BOP, FM I, and FM II are the most common mixture test preparations used for screening patch testing in most of the baseline series.
