Fragrance Allergy Statistics 2026: Europe and New EU Labels

Between 1% and 3% of people in Europe have a contact allergy to fragrance ingredients, according to the EU’s Scientific Committee on Consumer Safety in 2012.¹ The 2015 EDEN study put the clinically relevant figure at 1.9% of adults.² Since 31 July 2026, new EU fragrance allergen labelling rules apply.³

Fragrance allergy statistics at a glance

In short:

• Proven fragrance contact allergy affects roughly 1.9% of European adults in the EDEN study² and 1–3% of the general population in the SCCS estimate.¹
• The EU regulation behind the new labels estimates that 1–9% of the population is allergic to fragrance allergens.⁴
• Around 16% of eczema patients in the European population are sensitised to fragrance ingredients.¹
• More than 80 fragrance allergens must now be named on cosmetic labels, up from 24.^5,6
• From 31 July 2026, products that do not comply may no longer be placed on the EU market.³

How common fragrance allergy is in Europe

Three kinds of number circulate under the heading “fragrance allergy”, and they measure different things. This section covers the first: patch-test-proven contact allergy in ordinary adults. The figures are older than five years, so each carries its year.

The SCCS opinion of 2012 estimated that the frequency of contact allergy to fragrance ingredients in the general population in Europe is 1–3%.¹ The same opinion says contact allergy “persists lifelong”, and that typical sites are the face, the armpits and the hands.¹ It also notes that colognes, eau de toilette, deodorants and lotions are named significantly more often by fragrance allergic eczema patients.¹

The EDEN Fragrance Study, published in the British Journal of Dermatology in December 2015, tested adults aged 18–74 in Germany, Italy, the Netherlands, Portugal and Sweden. Of 12,377 people interviewed, 3,119 were patch tested.² The highest prevalence of contact allergy, 2.6%, was found for fragrance mix (FM) I, followed by 1.9% for FM II.² The conservatively estimated prevalence of fragrance contact allergy was 1.9% (95% CI 1.5–2.5). With lifetime contact dermatitis as the definition, it was 0.8% (95% CI 0.5–1.2).²

The study found that contact allergy to fragrances in women is about twice the rate in men.² One disclosure matters for context: the study was supported by the Research Institute for Fragrance Materials, Inc.²

A 2019 meta-analysis in Contact Dermatitis pooled 28 studies and 20,107 patch-tested people from the general population, with studies running up to 2017.⁸ The pooled prevalence of contact allergy to any allergen was 20.1%, with women at 27.9% and men at 13.2%.⁸ The most common allergen was nickel at 11.4%, followed by fragrance mix I at 3.5% (95% CI 2.1–5.4%), then cobalt at 2.7% and Myroxylon pereirae (balsam of Peru) at 1.8%.⁸

Fragrance allergy among patients tested at clinics

The second kind of number comes from people who were sent for patch testing because a doctor suspected an allergy. These rates are higher by design, so they must not be read as a share of the population.

The ESSCA network patch tested 22,581 patients in 2019–2020 in 53 departments across 13 European countries.⁷ Nickel was the leading reaction at 19.8%.⁷ Fragrance mix I and Myroxylon pereirae gave very similar results, at 6.80% and 6.62%.⁷ Fragrance mix II reached 3.77% and HICC 1.32%.⁷ A positive reaction to FM I, FM II, HICC and/or Myroxylon pereirae resin was seen in 10.3% (95% CI 9.8–10.7%) of patients tested.⁷

HICC after the ban

HICC, sold as Lyral, has declined further compared with 2013/14, when it stood at 1.7%. The authors say this confirms a downward trend following the ban by the European Commission in 2017.⁷ That regulation, dated 2 August 2017, banned HICC, atranol and chloroatranol, quoting the SCCS that these were the fragrance allergens which caused the highest number of contact allergy cases in past years.⁹ Atranol and chloroatranol are natural components of oak moss and treemoss extracts.⁹ Cosmetic products containing them could not be placed on the market from 23 August 2019 and could not be made available from 23 August 2021.⁹ For the history of those changes in perfumery, see our guide to IFRA rules and perfume reformulations.

Linalool and limonene: the oxidation problem

Newer patch-test research looks at the oxidised forms of linalool and limonene, the hydroperoxides, rather than the ingredients themselves. The ESSCA paper notes considerable added reactivity to limonene or linalool hydroperoxides.⁷ The studies below use different test concentrations, so compare them within a row of the table, not across countries.

• Germany, 2018–2020. Among 5,511 consecutive patients in the IVDK network, linalool hydroperoxides at 1% were positive in 483 patients (8.8%). Limonene hydroperoxides at 0.3% were positive in 170 patients (3.1%).¹⁰
• Spain, 2019–2024. Among 10,502 patients in the REIDAC registry, 2% and 4.1% reacted to limonene hydroperoxides at 0.2% and 0.3%. 2.9% and 5.3% reacted to linalool hydroperoxides at 0.5% and 1%. The study was published on 1 September 2026, making it the newest figure in this article.¹¹
• United Kingdom, 2013–2014. Among 4,563 consecutive patients in 12 centres, limonene hydroperoxide at 0.3% was positive in 5.3% and linalool hydroperoxide at 1.0% in 7.7%. In all, 10.1% reacted to one or both. In almost two-thirds of positive patients the reaction was clinically relevant.¹²
• Sweden, 2013–2020. Among 5,773 patients in Malmö, 7.0% reacted to oxidised linalool and 5.1% to oxidised limonene. Significantly increasing trends of contact allergy were observed, and affected patients were significantly younger and predominantly female.¹³

Two cautions belong with these numbers. The German authors warn that both preparations display an irritant potential with an increased risk of false positive reactions.¹⁰ And the UK audit found that the majority of patients did not react to any fragrance marker in the baseline series.¹²

Allergy and sensitivity: three numbers people mix up

The three figures that get quoted as “fragrance allergy” are not interchangeable:

• Proven allergy in the general population: about 1–3% (SCCS), with 1.9% in EDEN.^1,2
• Positives among clinic patients: 6.80% for fragrance mix I and 10.3% for any of the four fragrance markers in ESSCA.⁷
• Self-reported sensitivity: 27.8% to 34.7% of adults in four national surveys (32.2% overall).¹⁴

The third comes from Anne Steinemann’s 2019 study in Air Quality, Atmosphere & Health. National surveys in the US, Australia, the UK and Sweden (n = 1,137, 1,098, 1,100 and 1,100) found 32.2% of adults overall reported fragrance sensitivity, meaning adverse health effects from fragranced consumer products. The country figures were 34.7%, 33.0%, 27.8% and 33.1%. Reported problems included skin rashes (9.1%) and migraine headaches (12.6%).¹⁴ These are self-reports, mostly about air fresheners, cleaning products and other people’s scent. They are not patch-test-proven allergy, and they should never be added to the patch-test figures above.

The new EU allergen labels explained

Commission Regulation (EU) 2023/1545 was adopted on 26 July 2023, published on 27 July 2023 and entered into force on 16 August 2023.⁴ At that point 24 fragrance allergens needed individual labelling. The SCCS opinion of 2012 had identified 56 additional ones, and the regulation adds them.⁴ The Commission also says it updates existing entries, including by grouping certain substances.³ HPRA, Ireland’s regulator, describes the result as an expanded list of more than 80 fragrance allergens requiring mandatory on-pack disclosure.⁵

An allergen must be named when its concentration exceeds 0.001% in leave-on products or 0.01% in rinse-off products.³ Cosmetics Europe, the industry association, adds that substances with the same cross-sensitising properties can be listed under a common group name, and that labelling applies whatever the source, whether perfume, essential oil or impurity.⁶

Products placed on the market before 31 July 2026 may continue to be made available on the EU market until 31 July 2028.³ IFRA’s regulatory FAQ describes the same two dates as the end of the transition for placing products on the market and for withdrawal from the market.¹⁵ Older stock sold during that window is not an error. Lyral and Lilial, which are banned, were removed from the earlier list of 26 allergens.⁶

What the new labels mean for perfume wearers

The Commission’s own consumer message is plain: consumers may see more individual fragrance ingredients listed on cosmetic product packaging, and an ingredient appearing in the list does not mean that the product is unsafe.³ Cosmetics Europe makes a related point from the industry side: “The formula has not changed”, and there is no requirement to remove these substances.⁶ What changes is visibility. For someone who already knows they react to linalool, a longer list is useful information. For everyone else, it is a longer list of familiar names.

The 2017 regulation observes that consumers with contact allergy to fragrance allergens are often aware that they cannot tolerate scented products on their skin.⁹ If you suspect a reaction, the route to an answer is a patch test with a dermatologist, not a label or a statistic. This page informs; it does not diagnose, and no perfume can be called allergen-free.

When you do want to judge a scent before committing, a small vial is a sensible first step, although it tells you about the smell and not about allergy. Three in four decants Scento sent in October 2025 to September 2026 were 2 ml, according to the Scento Fragrance Index. Our guides to five ways to test perfumes before buying full size and to testing perfumes for your skin type cover the practical side. Natural extracts are allergen sources too, as our piece on natural versus synthetic perfume ingredients explains, and what IFRA compliance means is a separate question from allergy labelling. For more numbers on how people experience scent, see smell statistics.

How we compiled this

We used only named studies and regulators, all read on 19 October 2026. Prevalence figures are quoted as each paper states them, with the year of the data, and self-reported surveys are kept apart from patch-test results. A patch test places small amounts of suspected allergens on the skin under supervision; fragrance mix I and II are standard screening mixtures; “consecutive patients” means everyone tested in a clinic over a period, not a selected group. The Scento Fragrance Index line covers decant orders in Europe from October 2025 to September 2026 and is a share of paid units, not an allergy measure.
