EU Microplastics Ban in Cosmetics: The Transition Deadlines Most Formulators Are Getting Wrong

Encapsulated fragrance microcapsules are found across a substantial portion of rinse-off personal care products sold in Europe today. The polymer shells that hold those fragrance molecules in place — delivering controlled scent release through rinsing — are now subject to a REACH restriction with a compliance deadline of October 2027. For brands that haven’t already mapped their encapsulated fragrance exposure, that deadline is 15 months away.

Regulation (EU) 2023/2055 entered into force on 17 October 2023, adding Entry 78 to REACH Annex XVII and restricting intentionally added microplastics across hundreds of product categories. Cosmetics and personal care products sit near the centre of the restriction’s scope. Nearly three years in, a significant number of EU cosmetic brands have still not completed a compliance gap analysis on their own portfolios — partly because the transition periods create a sense of distance that the actual reformulation timeline doesn’t support, and partly because the definition of “microplastic” under the regulation is broader than many people expect.

Here’s what the restriction actually covers, where the deadline exposure is most acute, and what a credible compliance programme looks like in 2026.

What the Restriction Actually Covers — It’s Not Just Microbeads

Microbeads in rinse-off products were already attracting regulatory attention in Europe before 2023. The UK banned them in rinse-off cosmetics in 2018. Several EU member states had introduced national measures. The 2023 REACH restriction goes substantially further.

Under Entry 78 of REACH Annex XVII, a “microplastic” is defined as any material consisting of solid polymer particles with at least one dimension ≤ 5 mm, that is organic, insoluble, and resistant to degradation. The restriction applies to the intentional addition of such particles to mixtures or articles placed on the EU market.

For cosmetic formulators, the practical scope covers:

• Exfoliating microbeads in scrubs, cleansers, and face washes — the category most brands already addressed, but not always completely
• Glitter particles used decoratively in body products, highlighters, eye and cheek products, and festival cosmetics
• Polymeric microcapsules used for fragrance delivery, time-release active ingredients, or sensory texture modification
• Coloured polymer particles in foundations, eyeshadows, blushers, and face powders where colour effect relies on synthetic polymer substrates

Microcapsules and coloured polymer particles are where we see the most genuine surprise in regulatory reviews. A brand that conscientiously removed polyethylene microbeads from its scrub range five years ago may still have polymeric microcapsules throughout its fragrance-containing portfolio without realising those capsules now fall within the restriction. ECHA’s impact assessment estimated that cosmetics and personal care products collectively release approximately 3,700–4,800 tonnes of microplastics into the EU environment each year, and fragrance encapsulation represents a meaningful share of that figure.

The exemptions are real but narrow. Naturally occurring polymers that haven’t been chemically modified fall outside the definition — cellulose-based exfoliants from unmodified plant materials, for instance, are generally exempt. Polymers that are fully water-soluble at conditions of use are also outside scope. There’s a provision for microplastics that are permanently incorporated into a substrate with no possibility of release, but for most cosmetic applications — rinse-off or leave-on — demonstrating permanent incorporation is technically very difficult to sustain.

The Staggered Timeline — and Why 2027 Is Closer Than It Looks

The restriction doesn’t impose a single compliance date. Entry 78 sets product-category-specific transition periods, all measured from the October 2023 entry-into-force date:

Product Category	Transition Period	Compliance Deadline
Rinse-off cosmetics (shampoos, shower gels, face washes, scrubs)	4 years	October 2027
Encapsulated fragrances in rinse-off products	6 years	October 2029
Leave-on cosmetics (creams, serums, body lotions)	6 years	October 2029
Lip products	12 years	October 2035
Nail products	12 years	October 2035
Make-up (foundations, powders, eyeshadow, blush)	12 years	October 2035

The 6-year transition for encapsulated fragrances in rinse-off products — distinct from the 4-year period for other rinse-off microplastics — reflects ECHA’s recognition that polymeric fragrance delivery systems are technically harder to replace than exfoliating beads. That said, October 2029 is only 39 months away, and fragrance reformulation involving new delivery systems requires extensive consumer testing, stability assessment, and a full safety assessment update under Regulation (EC) No 1223/2009.

The 12-year periods for lip, nail, and make-up categories might suggest those brands can defer the question. In practice, that reasoning is flawed for two reasons. First, colour cosmetic formulations have long development cycles and high consumer sensitivity; reformulating a hero foundation or lip product in year 10 creates unnecessary risk. Second, and more immediately: the transition periods do not suspend the documentation obligation.

From the date of entry into force, any party placing a product containing in-scope microplastics on the EU market must be prepared to provide information on the presence and concentration of microplastics to professional users and downstream distributors on request. That obligation is active now, for every product category, regardless of which transition period applies.

The Encapsulated Fragrance Problem — Where Testing Becomes Non-Negotiable

Of all the compliance challenges under the 2023 restriction, encapsulated fragrances are generating the most complexity in practical regulatory work. Fragrance microcapsules — which deliver improved longevity, controlled release, and skin-feel benefits — are embedded in a wide range of rinse-off and leave-on formulations. Many brands buy finished fragrance compounds and don’t have full visibility into whether encapsulation technology is used, or what the capsule shell chemistry is.

That’s an ingredient transparency problem as much as a regulatory one. Under both the REACH restriction and Regulation (EC) No 1223/2009, cosmetic safety assessors need complete chemical identity and concentration data for every ingredient, including encapsulant polymers. If a fragrance supplier provides a compound without disclosing whether it contains polymeric capsules — or provides only a generic INCI listing — the brand is carrying unquantified compliance risk under Entry 78 and potentially an incomplete safety dossier under 1223/2009.

The testing challenge here is real and often underestimated. Standard cosmetic analytical methods — HPLC for actives quantification, GC-MS for fragrance profiling — don’t reliably identify or quantify solid polymer particles. Confirming the presence, identity, and concentration of polymer microcapsules in a cosmetic matrix typically requires pyrolysis-GC/MS, scanning electron microscopy (SEM) paired with energy-dispersive X-ray spectroscopy (EDX), or Fourier-transform infrared spectroscopy (FTIR) with dedicated particle analysis protocols. These are materials characterisation methods, not routine cosmetic testing. Most standard European cosmetic testing laboratories are not configured for this work.

Working with a partner lab that has materials characterisation capabilities — and that understands the regulatory context of REACH Entry 78 — is what makes the difference between a documented compliance position and a gap you discover at an audit. Having analytical data confirming the nature and concentration of polymer particles isn’t optional under the restriction; it’s the evidentiary basis for the declarations you’re obligated to provide.

Building a Defensible Compliance Programme Before Your Deadline

There’s no shortcut through this, but the work is structured and manageable if started now. In our experience supporting European cosmetics brands through regulatory transitions, the companies that handle this well share a consistent approach.

Start with a portfolio mapping exercise. Identify every SKU that could contain intentionally added synthetic polymer particles. This means reviewing formulation documentation, INCI lists, and — critically — ingredient technical data sheets for fragrance compounds, colourants, and functional additives. Don’t assume a supplier’s INCI declaration would flag polymer capsules; it often doesn’t.

Go back to your fragrance and speciality ingredient suppliers with specific questions. Ask explicitly whether compounds contain polymeric microcapsules, and request technical data that states the capsule shell chemistry. If a supplier is unwilling or unable to provide this, that’s a material gap in your dossier that needs to be resolved, either through independent analysis or supplier substitution.

Confirm which particles are genuinely in scope. Not every polymer particle triggers the restriction. Work with your safety assessor to evaluate whether specific polymers are biodegradable, naturally derived, or fully water-soluble under use conditions, and document the technical basis for any exemption claim. This analysis should be kept in the product information file.

Map your reformulation timeline against your actual compliance deadline, not against the calendar. For rinse-off products with polymer microbeads (excluding encapsulated fragrances), October 2027 is 15 months away. Cosmetic reformulation — including stability testing, consumer testing, safety assessment update, and CPNP notification amendment — typically takes 18 to 36 months. For any SKU in this category where reformulation hasn’t started, the timeline is already tight.

Build documentation into your ongoing Regulation 1223/2009 compliance cycle. The microplastics restriction shouldn’t be treated as a standalone REACH project sitting outside the normal product information file process. Information on microplastics content belongs in the PIF and should be reviewed at each routine safety assessment update. Integrating it here is far more efficient than maintaining a parallel compliance track.

One aspect that catches some brands off guard: the restriction applies to products placed on the EU market, regardless of where they’re manufactured. A European brand sourcing finished products from a manufacturer outside the EU — or re-labelling products from Asian suppliers — carries full REACH Entry 78 compliance responsibility as the EU importer. Sourcing teams and supply chain managers need to be part of this conversation, not just regulatory affairs.

Where the Portfolio Review Should Focus in Mid-2026

We’re now approximately 33 months into the restriction’s transition period for rinse-off cosmetics. That’s essentially the midpoint — close enough to the 2027 deadline that reformulation needs to begin now, but not so late that decisions made today won’t have an effect in time.

The highest-priority portfolios for immediate attention are rinse-off products containing fragrance compounds sourced without explicit polymer disclosure, exfoliating rinse-off products where the exfoliant chemistry hasn’t been verified against the microplastics definition, and any product using decorative glitter that hasn’t been confirmed as biodegradable or otherwise outside scope.

For leave-on products and make-up, October 2029 and 2035 deadlines allow more time — but the documentation obligation is live, and any brand planning a reformulation or reformulation-free compliance argument needs the analytical work done to support it.

The brands that will navigate this smoothly are the ones treating 2026 as the year to close their analytical and documentation gaps. The ones that will face difficulty are those watching the 2027 deadline move toward them without having started.
