Three EU Cosmetic Regulations Changing Everything in 2026

The European Union is rolling out three major cosmetic regulatory changes within an 11-week window in summer and autumn 2026 — the most consolidated regulatory inflection point the cosmetic industry has faced in over a decade. Each one would be significant on its own. Landing together, they reshape what labels show, what brands can sell, and what consumers can verify.

This is the complete map: what changes, when, why it matters.

The three regulations, at a glance

Date	Regulation	What changes
30 July 2026	Implementing Decision (EU) 2025/1175	The official EU ingredient naming glossary expands to ~30,418 entries — the biggest update in 7 years
31 July 2026	Commission Regulation (EU) 2023/1545	Fragrance allergen disclosure expands from 26 to 82 declared substances
17 October 2027	Regulation (EU) 2023/2055 (microplastic phase-out, leave-on cosmetics phase)	Intentionally added microplastics prohibited in leave-on cosmetics — preparation across 2026

Each of these is significant. Together, they mean every cosmetic product sold in the EU is being relabelled, reformulated, or both, across 2026.

Why three at once

This isn’t coincidence. Three forces converged:

1. The EU’s modernisation cycle. Under the broader Chemicals Strategy for Sustainability (CSS) and the Green Deal, the European Commission is updating chemical-management regulation across multiple sectors simultaneously. The cosmetic regulatory updates ride this wider modernisation.

2. Backlog clearance. The 2012 SCCS opinion on fragrance allergens, the post-2019 stack of SCCS opinions feeding the INCI Glossary update, and the long-running microplastic restriction work all reached the end of their consultation-and-codification cycles around the same time.

3. Industry coordination. Major brands have been signalling readiness for a single consolidated relabelling cycle for years, rather than three separate ones. The EU obliged.

The result: a single 2026 compliance push for brands, and a single 2026 transparency improvement for consumers.

1. The INCI Glossary update — 30 July 2026

Implementing Decision (EU) 2025/1175 updates the official EU glossary of ingredient names from ~24,000 entries (under the 2019/701 decision) to roughly 30,418 entries.

What it changes:

• ~6,000 new ingredients get standardised EU INCI names — mostly new peptide actives, biotech-derived equivalents, modern silicones, and post-2019 UV filters
• Hundreds of existing names refined for accuracy — ceramide variants, botanical Latin binomials, source-distinction for natural vs synthetic versions
• Cross-references and synonym tables improved — easier mapping between old and new names
• Alignment with recent SCCS opinions — entries reflect current Annex II/III status

What it means: your products’ names on labels may shift, but the chemistry doesn’t. Brands relabel; consumers see more precise ingredient names. Our full explainer is here.

2. Fragrance allergen expansion — 31 July 2026

Commission Regulation (EU) 2023/1545 triples the number of fragrance compounds that must be declared on cosmetic labels — from the original 26 (in effect since 2003) to 82 substances.

What it changes:

• 56 new fragrance allergens must be declared individually on the INCI list when above 10 ppm in leave-on / 100 ppm in rinse-off
• The expansion covers common essential oil constituents (camphor, carvone, linalyl acetate, menthol, α-pinene, vanillin, etc.) and modern synthetic perfumery materials (Iso E Super, acetylcedrene, methyl salicylate, etc.)
• Two-year sell-through period: products on shelves before 31 July 2026 may continue to be sold until 31 July 2028

What it means: labels show more declared allergens; the chemistry doesn’t change. People with diagnosed fragrance allergy gain visibility into 56 previously-hidden substances. Natural and essential-oil-heavy products show the biggest INCI-list expansion. Our full breakdown is here.

3. Microplastic phase-out (preparation year) — leave-on cosmetics by October 2027

Regulation (EU) 2023/2055 under REACH already prohibits intentionally added microplastics across consumer products, with a staged phase-out:

• October 2023: rinse-off exfoliating products with microbeads (immediate)
• October 2023: loose glitter with PET (immediate)
• October 2027: leave-on cosmetics (makeup, sunscreen, primers, mascara)
• October 2029: rinse-off cosmetics not in the immediate category
• October 2035: full enforcement across all permitted exemptions

2026 is the preparation year for the October 2027 leave-on phase. Brands using acrylates copolymer film-formers, PTFE for slip, polyurethane for water-resistance, or other in-scope synthetic polymer microparticles are mid-reformulation. Compliant alternatives — cellulose-based, modified-starch, biodegradable polyhydroxyalkanoate (PHA), silicone elastomers (which aren’t microplastics under the rule), waxes — are being adopted across the industry.

What it means: by mid-2027, most long-wear makeup, mascara and waterproof sunscreens will have been reformulated. Texture and performance may shift subtly. Our microplastics deep-dive is here.

What the three together mean for consumers

Across 2026 you can expect:

Most cosmetic products will have new labels. A combination of new INCI names, expanded allergen disclosures, and reformulation-driven INCI list changes means almost every product sold in the EU will look different in mid-2026 than it did in late 2025.

Labels will look “busier” but more transparent. Specifically:

• More named ingredients (because the glossary distinguishes variants more precisely)
• More declared allergens after the Parfum marker (because 56 more substances are disclosed)
• Microplastic ingredients gradually disappearing from leave-on formulations

Some “natural” claims will get harder to make. The glossary refinement and allergen expansion both reduce the room for marketing language that obscured ingredient identity. Brands that have leaned heavily on “natural perfume” or “clean fragrance” claims will see their INCI lists tell a different story than their front-of-pack copy.

Reformulations for microplastic compliance may affect texture. Particularly visible in long-wear foundations, primers, and sweat-resistant sunscreens — many of which relied on acrylates copolymers and PFAS-class film-formers. The replacements work but feel different.

No products are suddenly less safe. Almost all relabelling is about transparency, not safety. The chemistry of the substances already on shelves remains regulated under Annex II / Annex III, and the changes happening in 2026 are about better disclosure, not new prohibitions.

What it means for brands

For brand R&D, regulatory affairs, and marketing teams, 2026 is the busiest compliance year since the original 2009 Regulation came into force. The actual workload involves:

• Cross-referencing every current INCI name against the new glossary
• Running fragrance composition analyses to identify the 82 declared allergens above threshold
• Reformulating leave-on products containing in-scope microplastic ingredients
• Updating Product Information Files (PIF) held by the EU Responsible Person
• Coordinating print artwork with packaging suppliers (lead times of weeks to months)
• Training customer service teams on what to say when consumers ask about label changes
• Updating digital product pages, e-commerce listings, and brand-site ingredient declarations

Larger brands started preparation in mid-2025; most are on track. Indie brands and small-batch makers face the biggest squeeze — many discover the compliance requirements late and run into supplier capacity issues during peak preparation in Q2 2026.

What it means for skincare media coverage

Expect significant beauty-press attention across summer 2026:

• July 22–31: explainer pieces on the INCI Glossary update and fragrance allergen expansion. The two land in the same week and will be covered together by major beauty publications (Allure, Byrdie, Refinery29, Glossy, the FT’s Behind the Brand, Cosmetics Business).
• August: post-deadline reaction pieces — which brands handled the transition well, which got caught out.
• September: microplastic-preparation pieces previewing the 2027 leave-on phase.
• October: 1-year-in retrospective on the 2026 changes.

For consumers paying attention, this is a year-long opportunity to understand cosmetic regulation in unusual depth. Most years, EU cosmetic regulation is invisible to consumers. 2026 is the year it surfaces.

How LuxSense handles all three

The LuxSense ingredient database is synchronised with the EU CosIng portal, the EU INCI Glossary, the Annex II/III restriction lists, and the SCCS opinion stream. As each of the 2026 changes propagates through the official EU sources, the LuxSense database updates automatically. This means:

• Products with old labels (pre-2026 INCI names, 26-allergen disclosure) scan and resolve correctly against the database
• Products with new labels (post-2026 INCI names, 82-allergen disclosure) also scan correctly — the database understands cross-references
• Microplastic ingredient profiles are scored against current phase-out status; a film-former that is compliant in 2026 but scheduled for phase-out in 2027 carries a lower score than a fully exempt alternative (methodology details how this is weighted)
• Allergen flagging covers all 82 substances, not just the original 26 — so users with confirmed fragrance allergy get flagged even on products whose labels haven’t been updated yet

The point of LuxSense’s approach is to track the regulators in real time so consumers don’t have to learn Implementing Decisions, Commission Regulations or REACH titles. The transparency the EU is mandating in 2026 should be a one-line answer when you scan a product, not a compliance research project.

FAQ

Will my favourite products be reformulated?

Most won’t — at least not for the glossary update or the fragrance allergen expansion. Both are about disclosure, not chemistry. Some will be reformulated for the microplastic phase-out, particularly long-wear makeup. Brand-by-brand, watch for visible texture changes in late 2026 and through 2027.

Why is the EU doing this all at once?

A combination of timing of underlying scientific work, the EU’s broader modernisation cycle under the Chemicals Strategy for Sustainability, and industry coordination favouring a single consolidated compliance push.

Will products get more expensive?

Relabelling itself is a one-time cost brands absorb in normal artwork-refresh cycles. Reformulation for microplastic compliance is more substantial but largely complete for major brands by mid-2026; price impact has been modest.

What about products sold in the UK?

The UK retained EU cosmetic regulation post-Brexit and has historically maintained alignment. The UK MHRA hasn’t yet announced equivalent 2026 updates. Products dual-marketed in the EU and UK will likely use the new EU labelling by default.

What about US-imported products on EU shelves?

Every product sold in the EU must comply, regardless of where manufactured. US, Korean, and Japanese imports will use EU INCI names, EU allergen disclosures, and be microplastic-compliant by their applicable deadlines.
