The Microplastics Clock: Which Cosmetic Formulas the EU Is Phasing Out

Short answer: the EU's restriction on synthetic polymer microparticles is already in force, and it is being phased in by product format rather than by ingredient — rinse-off formulas first, leave-on next, colour and nail formats last. The work that matters now is auditing which of your raw materials are still polymer particles, and starting the reformulation cycle early enough to re-run stability and preservative testing.

Most brands read "microplastics ban" and think of the abrasive beads in a face scrub. That reading is about five years out of date. The restriction the EU adopted in 2023 targets a much wider class — synthetic polymer microparticles as a material definition, not a list of named scrub ingredients — reaching into film formers, texturising agents, encapsulated actives, glitter and the sensory modifiers that make a cream feel expensive. Because the phase-in is organised by product format, two SKUs on the same shelf can have reformulation deadlines five years apart.

Here is what the restriction actually covers, when each format has to comply, and how a normal product range gets audited without a consultant's invoice.

What the EU actually restricted

The instrument is Regulation (EU) 2023/2055, which amended REACH Annex XVII to restrict synthetic polymer microparticles. The definition is deliberately material-based rather than ingredient-based: solid particles composed of polymers that are insoluble, non-degradable and below five millimetres in size, present at or above a threshold concentration in the product. The original abrasive microbead prohibition that many formulators remember (rinsed-off exfoliating particles) became the first, narrowest tranche of a wider restriction.

Three consequences follow from a material definition, and each one catches brands that only checked an ingredient list:

1. A supplier's "biodegradable" claim is not automatically a pass. The exemption route for degradable polymers depends on demonstrating degradability by a defined standard, not on a marketing descriptor. If the document you hold is a product brochure rather than a test report, you do not have a conclusion.
2. The threshold is a concentration in the finished product, not a presence/absence test. A polymer particle that appears at very low levels, or that arrives as a contaminant in a blend, still has to be assessed against the threshold.
3. Function does not exempt a material. Opacifiers, rheology modifiers, sensory enhancers, film formers and encapsulated payloads all fall inside the same material definition if they meet it.

The deadline roadmap, format by format

The phase-in exists because the Commission accepted that reformulating a rinse-off exfoliant is a different project from reformulating a long-wear foundation. Read the table as a capacity-planning tool: it tells you which projects have to be in the lab now and which can wait a procurement cycle.

Two rules make the table practical. The clock is tied to placing on the market, so a product you launch next quarter inherits the horizon of its own format, not the format you shipped five years ago. And reformulating for a different reason does not reset it: change a preservative system and you inherit the microplastic horizon at the same time — which is why reformulation projects should be bundled rather than run one at a time.

Which SKUs in a normal range are in scope

The audit is not a philosophical exercise. In a typical skincare, body and colour range, the following are the places polymer particles actually hide:

• Scrubs and body polishes — abrasive particles, including the "natural-looking" ones that are in fact a polymer composite.
• Peel-off and film masks — the film former itself, plus any encapsulated colour or active.
• Long-wear foundations and concealers — film formers, soft-focus powders, and the elastomer gels that give cushion.
• Mascara and eyeliner — rheology modifiers and wax-polymer blends that build volume and wear.
• Nail systems — suspension agents and the particles that create texture or a matte effect.
• Toothpaste-style and oral-adjacent formats — where a flavour of the restriction applies to rinse-off cleaning products.
• Fragrance encapsulation — the capsule wall material in a long-lasting delivery system, which is why fragrance houses started reformulating before most brands did.

The one that surprises people most often is not a scrub at all. It is a texture agent used at a fraction of a percent purely to make a serum feel silky. Nobody put it there to exfoliate anything; it is still a synthetic polymer microparticle if it meets the definition.

The myth that costs a season

The most widespread wrong belief is that this is a scrubs regulation. The second most widespread is that removing a polymer is a one-line change to the ingredient list.

Neither is true, and the second is where the schedule actually breaks. Removing a polymer particle changes the rheology of the base, which changes fill weight, which changes the amount a pump delivers per stroke, which changes how the product feels on the third application rather than the first. A viscosity shift of a few percent at 25°C becomes a different product at 40°C in a warehouse, and the sensory panel will not forgive it. That chain — formula, then fill weight, then dispenser, then consumer perception — is why a "simple substitution" typically consumes one reformulation cycle and one stability programme.

A third belief appears in procurement conversations rather than regulatory ones: that a compliant base already in the catalogue means you are covered. A stock base is compliant for the format it was designed for. If your finished product's format group is different, the base has to be re-checked against the definition rather than inherited with the paperwork.

What reformulation actually involves

Read this as the sequence, not a checklist of ideas:

1. Raw-material mapping. Every component in the bill of materials gets screened against the material definition — including components that arrive inside a blend or a fragrance compound and never appear as a separate line.
2. Exemption review. Where degradability or solubility may exempt a material, the evidence has to be a report to a defined standard, held on file and traceable to the supplier and the batch.
3. Substitution and prototype. Replacements are chosen for the function, not the name: an ester for slip, a silica or starch for texture, a modified cellulose for rheology, a linear silicone where a volatile one was doing the work.
4. Stability re-run. Accelerated and real-time studies restart, because the dispersed phase has changed. This is a scheduling constraint, not a formality — see our notes on how stability testing is structured.
5. Preservative efficacy re-test. Any change to the water activity, the particle load or the pH window can alter how well the preservation system performs. A formula that passed before substitution is not covered.
6. File update. The product information file, the safety assessment and the notification all follow the formula. A change to the quantitative composition is not a silent edit.

Because documentation is where the timeline is lost, the useful move is to treat the material map as a permanent asset: a supplier-level register of which raw materials are polymer particles, with the evidence attached, updated once a year rather than rebuilt for every launch.

A 90-day working checklist

• Days 1–10 — inventory. Pull every raw material and every finished format, and tag each against the four format groups in the table above.
• Days 11–25 — evidence. For each flagged material, obtain either a degradability/solubility report to a defined standard or a written confirmation that the material is out of scope. No brochure PDFs.
• Days 26–45 — prototype. Build replacements for the highest-risk format first, which is almost always long-wear colour, because pigment-polymer interactions are the hardest to re-tune.
• Days 46–70 — test. Accelerated stability plus preservative efficacy, with a retained Golden Sample comparison so the colour and texture decision is made against a physical reference rather than a memory.
• Days 71–90 — paperwork and label. Update the safety assessment, the product information file and the artwork, then route the change through whoever holds your notification.

If your range includes formats with a 2029 or 2035 horizon, the correct decision today is often not to reformulate but to build the map — so that when the project starts, it starts with evidence rather than with archaeology.

Our own batches are documented the same way the audit wants them: analysis, stability and microbiological records against the specification actually produced, and a retained Golden Sample for every colour and texture decision. That is the file a reformulation is built on. The route for the reformulations that regulation forces is set out in our guide to the reformulation cost of a rule change, and the broader packaging side of the same regulatory wave is covered in our PPWR and green claims guide.

FAQ

Q: Does the EU microplastics restriction cover ingredients other than scrub beads? A: Yes. It restricts synthetic polymer microparticles as a material class — solid, insoluble, non-degradable polymer particles below five millimetres at or above a concentration threshold — so film formers, texture agents, encapsulated actives and glitter fall inside it if they meet the definition.

Q: When does my leave-on cream have to be free of synthetic polymer microparticles? A: On the published phase-in, other rinsed-off products reach their horizon in October 2027, and leave-on cosmetic products and fragrance encapsulation follow in October 2029. Make-up, lip and nail leave-on formats have the longest runway, to October 2035.

Q: Can I rely on my supplier's biodegradable claim for a polymer particle? A: Not on a marketing claim. The exemption depends on demonstrating degradability by a defined standard and holding that evidence on file, traceable to the supplier and the batch. Treat a specification sheet as a starting point, not as proof.

Q: Does removing a polymer particle require re-running stability and preservative testing? A: Yes. Changing the dispersed phase alters rheology, fill weight and dispenser behaviour, and can shift how well the preservation system performs. Both the stability programme and the preservative efficacy test have to be re-run against the new composition before the file is updated.
