EU Fragrance Allergen Labels: 2026 Guide

Cosmetic ingredient lists in Europe are getting longer—not necessarily because formulas contain more fragrance, but because labels must now identify more fragrance allergens by name.

Since July 31, 2026, newly placed EU cosmetic products have had to follow an expanded set of fragrance-allergen disclosure requirements. Products placed on the market before that date can continue moving through shops until July 31, 2028, which means old and new labels may appear side by side during the transition.

The extra names are intended to help people with known contact allergies avoid specific substances. Their presence is not, by itself, a warning that a cosmetic is unsafe for everyone.

What Changed on July 31, 2026?

The European Commission expanded Annex III of the EU Cosmetics Regulation through Regulation (EU) 2023/1545. The update brought the disclosure system from 24 individual fragrance allergens to more than 80 entries, including some grouped names that cover related substances.

The transition works in two stages:

A cosmetic that did not meet the expanded requirements could no longer be placed on the EU market after July 31, 2026.
A compliant product placed on the market before that date may continue to be made available to consumers until July 31, 2028.

“Placed on the market” generally refers to the first supply of a product in the EU. “Made available” covers later distribution, including retail sale. That legal distinction explains why a shop can still carry older stock with a shorter ingredient list without necessarily violating the transition rules.

Which Products Are Covered?

The rules apply to cosmetics, including products such as:

Perfume and eau de toilette
Face and body moisturizers
Sunscreen and makeup
Shampoo, conditioner, and styling products
Soap, shower gel, and other rinse-off products
Deodorant and antiperspirant

The requirement depends on the concentration of a listed allergen in the finished product, not whether the substance was added as a stand-alone ingredient. An allergen contributed by a fragrance mixture, essential oil, botanical extract, or another material can still require declaration when the applicable threshold is exceeded.

This is why a label may list both parfum and individual names such as linalool, limonene, citral, geraniol, or coumarin. “Parfum” describes the fragrance mixture; the additional terms disclose specified allergens within or contributed to the formulation.

What Are the Disclosure Thresholds?

The familiar EU thresholds remain:

More than 0.001% in leave-on products
More than 0.01% in rinse-off products

Leave-on products stay on the skin or hair, such as creams, perfume, and many styling products. Rinse-off products, such as shampoo or shower gel, are intended to be removed with water.

The threshold is a labeling trigger, not a dividing line between “safe” and “toxic.” A listed name below the threshold may not appear individually, and a name above the threshold does not mean everyone who uses the product will react.

Some new entries are grouped allergens. In those cases, authorities can require a defined group name when the combined concentration of related substances exceeds the threshold. That keeps a label usable while still giving sensitized consumers a consistent term to recognize.

Why Fragrance Allergens Are Named Separately

Fragrance contact allergy is an immune reaction that can occur after a person becomes sensitized to a substance. Later skin contact with that allergen may trigger allergic contact dermatitis. The ingredient-list requirement supports avoidance by people who already know which substance affects them.

It does not diagnose an allergy. Redness, itching, or irritation after using a cosmetic can have many causes, including irritant contact dermatitis, another allergen, or an unrelated skin condition. A label scanner can identify a name, but it cannot determine why a rash occurred or substitute for medical evaluation.

The European Commission explicitly tells consumers that an allergen appearing in the ingredient list does not mean the product is unsafe. The value of disclosure is precision: someone sensitized to hydroxycitronellal, for example, can look for that term instead of trying to avoid every scented product based on smell alone.

New Names You May Start Seeing

Along with long-familiar disclosures such as limonene, linalool, citronellol, eugenol, geraniol, and benzyl salicylate, expanded labels may include names such as:

Acetyl Cedrene
Alpha-Terpinene
Amyl Salicylate
Anethole
Benzaldehyde
Camphor
Carvone
Linalyl Acetate
Menthol
Pinene
Rose Flower Oil/Extract
Tetramethyl Acetyloctahydronaphthalenes

This is not a complete list, and memorizing it is rarely useful unless you are avoiding a specific diagnosed allergen. The exact INCI name—or the legally defined group name—is more valuable than an online “dirty ingredients” list that treats every fragrance substance as equally risky.

Natural origin does not remove disclosure obligations. Essential oils and botanical extracts contain chemical constituents, and some can contribute listed fragrance allergens. Conversely, a synthetic ingredient is not automatically more allergenic simply because it was manufactured rather than extracted from a plant.

Why Old and New Labels May Differ

During the transition, two packages of the same product can show different ingredient lists. Possible reasons include:

One unit was placed on the market before July 31, 2026 and another afterward.
The brand updated only the disclosure names, without materially changing the fragrance formula.
The product was reformulated at the same time as the label update.
The packages were produced for different countries with different rules.

A longer list therefore does not prove that a product suddenly contains more fragrance. If the difference matters, compare the full INCI list and ask the manufacturer whether the formula changed or only the label declaration.

How the EU Compares With Canada and the United States

Canada has adopted a closely aligned expanded list and similar thresholds. Its rules require new cosmetics to disclose the additional fragrance allergens from August 1, 2026, with a later 2028 date for existing products. This alignment should make many Canadian and EU labels more informative and more consistent over time.

The United States has a different system. FDA requires retail cosmetics to carry ingredient declarations, but components of a fragrance can generally appear under the collective term “fragrance” or “perfume.” FDA also cautions that front-label terms such as “hypoallergenic,” “fragrance-free,” and “for sensitive skin” do not have a federal standard that guarantees a product will suit an allergy-prone consumer.

As a result, the same formula may disclose more individual fragrance names on an EU or Canadian package than on a U.S. package. That difference reflects labeling rules, not necessarily a different formula or a safety violation.

A Practical Way to Read the New Labels

Use the added transparency without turning every unfamiliar word into an alarm:

Start with your purpose. General preference, irritation, and a diagnosed contact allergy require different levels of avoidance.
Match exact names. If a clinician has identified an allergen, use the provided name and known synonyms rather than avoiding every ingredient that sounds similar.
Check “parfum” and the named allergens. The individual disclosures do not necessarily describe every substance in the fragrance mixture.
Notice the product type. A rinse-off shampoo and a leave-on serum use different disclosure thresholds and create different patterns of contact.
Do not rely on scent alone. “Unscented” can refer to the sensory result, while a formulation may still use fragrance materials for another purpose.
Save a label that works for you. Formulas and packages change, so compare the current ingredient list when repurchasing.

For a broader introduction, see how to identify chemicals in everyday products. Our guide to parabens in personal care products covers a separate cosmetic-ingredient category that should not be confused with fragrance allergens.

Toxic Scan can make long INCI lists easier to parse and can surface names such as limonene or benzyl salicylate. It cannot diagnose contact allergy or determine personal tolerance from a photo, so use the scan as a reading aid rather than a medical verdict.

The Bottom Line

The EU's 2026 transition gives consumers more specific fragrance information on cosmetic labels. New products placed on the market after July 31 must follow the expanded requirements, while eligible older stock can remain available until July 31, 2028.

More names do not automatically mean more fragrance or a less safe product. The change is most useful for people who know the exact allergen they need to avoid—and for everyone else, it offers a clearer look at what “parfum” may contain above the disclosure thresholds.
