Perfume Labeling Requirements: US vs. EU

U.S. and EU perfume labels diverge on one requirement above all others: the EU makes you name individual fragrance allergens in the ingredient list, and the U.S. does not. EU cosmetic labels must declare 26 named fragrance allergens today, and Regulation (EU) 2023/1545 expands that list to more than 80 entries, applying to products placed on the EU market from 31 July 2026 and to products made available on the market by 31 July 2028. In the U.S., the entire fragrance may still appear as the single word "Fragrance" — MoCRA directs FDA to write allergen-disclosure rules, but no proposed rule has been published and no effective date is set.

The same bottle, two ingredient lists — an EU label must name individual fragrance allergens; a U.S. label may still say only “Fragrance.”

How Do U.S. and EU Perfume Labels Differ?

What Does the Same Fragrance Look Like on a U.S. vs. EU Label?

Same product, same fragrance — two different ingredient lists depending on the market. The examples below illustrate the practical effect of the rules.

The ingredient lists above are illustrative. The exact allergens that appear on any label depend on the specific fragrance composition and the use level in the finished product. Your supplier's EU allergen breakdown is what determines the named allergens for your label.

For fragrance brands selling in both regions — or planning to expand internationally — labeling sits at the intersection of compliance, supply-chain documentation, and consumer trust. The rest of this guide walks through each requirement in detail, with the long allergen lists tucked into expandable drawers for reference.

One product, many markets — the label rules that apply are the rules of the market where the product is sold.

What Does Each Region Require on the Label?

What Must a U.S. Cosmetic Label Include?

In the U.S., perfumes are regulated as cosmetics under the Federal Food, Drug, and Cosmetic Act (FD&C Act). Cosmetic labels must include:

• Identity of the product (e.g., "Perfume," "Eau de Parfum")
• Net quantity of contents (e.g., fl. oz., mL)
• Business information (manufacturer, packer, or distributor)
• Ingredient declaration in descending order — the fragrance itself may appear simply as "Fragrance" or "Parfum"
• Warnings and directions, when applicable (flammability, safe use)
• Adverse-event contact information — since 29 December 2024, MoCRA requires every cosmetic label to carry a domestic address, domestic phone number, or electronic contact through which the responsible person can receive adverse event reports

Currently, U.S. cosmetic regulations do not require brands to list individual fragrance allergens on the label. Allergenic components like limonene, linalool, or citral may be captured under the single word "Fragrance."

What's changing: The Modernization of Cosmetics Regulation Act (MoCRA, 2022) directs FDA to identify which substances count as fragrance allergens, to require them on cosmetic labels, and to consider existing international requirements — the EU's included — when it does (21 U.S.C. 364e(b)). The statute set an 18-month deadline for a proposed rule from its 29 December 2022 enactment; as of August 2026 no proposed rule has appeared in the Federal Register, so U.S. labels carry no allergen-disclosure obligation yet. FDA’s 2026 Unified Agenda now targets a proposed rule for November 2026 — an agenda projection, not a binding date. Brands that already maintain detailed allergen documentation today will be better positioned when those rules land.

What Does the EU Require Beyond That?

In the European Union, perfumes and fragranced cosmetics are regulated under Cosmetics Regulation (EC) No 1223/2009. The label requirements are similar to the U.S. — identity, net contents, responsible person, ingredient list — but the EU adds mandatory fragrance allergen disclosure above set thresholds.

These thresholds apply whether the allergens come from natural essential oils or synthetic ingredients. Many naturals contain several listed allergens at once — which is why supplier documentation matters.

Which Allergens Must an EU Label Name?

The EU's allergen list has two layers. The original list of 26 named fragrance allergens is what cosmetic labels must declare today; two of those, Lilial (butylphenyl methylpropional) and HICC (Lyral), have since been banned from EU cosmetics outright, leaving 24 in active use. Regulation (EU) 2023/1545, in force since 16 August 2023, expands the list to more than 80 entries, adding individual chemical substances and named plant species and extracts whose composition makes them inherent allergen carriers.

That expansion is not yet in force for every product: new products placed on the EU market must comply from 31 July 2026, and products already on the market must comply, or be withdrawn, by 31 July 2028.

The two banned substances are starting to fall in the U.S. as well: California’s AB 496 bans butylphenyl methylpropional (Lilial — listed there as lily aldehyde, CAS 80-54-6) from cosmetics sold in the state beginning 1 January 2027.

Are Essential Oils and Naturals Covered Too?

The expansion's biggest practical impact is on natural fragrance work: many widely used essential oils and extracts now appear in Annex III by name. A single oil can trigger several allergens at once because of its inherent chemical composition.

Lavender (Lavandula angustifolia) is one of the botanical species Regulation (EU) 2023/1545 names directly — the oil itself is a disclosure trigger.

Headline categories — visible to anyone formulating with naturals:

• Rose ketones (damascones, damascenone)
• Pinene / terpene group
• Rose oils & absolutes (Rosa centifolia, damascena, gallica)
• Jasmine (Jasminum spp.)
• Ylang-ylang (Cananga odorata)
• Citrus oils (bergamot, lemon, sweet/bitter orange)
• Lavender (Lavandula angustifolia, hybrida)
• Mint (Mentha piperita, spicata)
• Patchouli (Pogostemon cablin)
• Sandalwood (Santalum album)
• Cedarwood (Cedrus atlantica, Juniperus virginiana)
• Eucalyptus (E. globulus, E. radiata)
• Verbena (Lippia citriodora)

For the authoritative complete enumeration — including exact substance forms, CAS numbers, and specific isomer designations — refer to Regulation (EU) 2023/1545 on EUR-Lex and Annex III of Cosmetics Regulation (EC) No 1223/2009.
