The EU Just Removed Three "Natural" Repellent Ingredients From Its Approved List

By Mosticare Editorial | Published 2026-04-30

Today, 30 April 2026, a regulatory deadline quietly passed in Brussels that will affect millions of European consumers without most of them knowing it.

Three active ingredients widely used in mosquito repellents marketed as "natural", geraniol, eugenol, and thymol, have reached the end of their authorisation period under the EU Biocidal Products Regulation (BPR) 528/2012 and are no longer supported in the active substance review programme. In practical terms, this means the European Commission will issue a formal non-approval decision for each substance. Once that decision is published, products containing these ingredients in repellent or insecticide formulations cannot legally be placed on the EU market.

This is not a recall. Products already on shelves are not immediately seized. But new stock cannot be manufactured or imported for EU sale using these actives, and retailers will be expected to phase out existing inventory. For consumers, this raises a straightforward question: is the repellent you currently use still EU-legal?

What Are These Ingredients, and Why Are They In Your Repellent?

Geraniol, eugenol, and thymol are naturally occurring organic compounds found in plants. Geraniol is extracted from geranium and rose oils. Eugenol is the dominant compound in clove oil, responsible for its distinctive smell. Thymol is the principal monoterpene in thyme oil.

All three have demonstrated mosquito-repellent properties in laboratory conditions. Because they derive from plants rather than synthetic chemistry, manufacturers have been able to market products containing them as "natural," "botanical," or "plant-based", a category that commands significant consumer premium, particularly in northern and western European markets where concerns about synthetic chemicals are more pronounced.

The problem is that "natural" and "safe" are not synonyms, and they are certainly not synonyms in EU regulatory terms. The BPR applies the same evidentiary standard to plant-derived active substances as it does to synthetic ones: manufacturers must demonstrate efficacy, safety for humans and the environment, and provide full toxicological dossiers. The regulatory process does not give natural substances a free pass because they come from a geranium rather than a petrochemical facility.

Why Did These Substances Fail the Review?

The answer is not exactly that they "failed", it is that no company chose to fund their defence.

Under the BPR review programme, approval of an active substance requires an industry notifier, a company or consortium, to submit a comprehensive technical dossier and bear the costs of evaluation. This is an expensive, multi-year process that can cost millions of euros. For high-volume synthetic actives like DEET or Icaridin, the commercial logic is clear: the investment pays off in continued market access.

For plant extracts like geraniol, eugenol, and thymol, the economics are harder. These compounds cannot be patented the way synthetic molecules can, so any manufacturer who funds the approval process effectively creates a public good that competitors can exploit without contributing. The result is a collective-action problem: no single company has sufficient incentive to bear the full cost.

In the case of geraniol, the European Chemicals Agency (ECHA) confirmed in July 2025 that no notifier submitted support for continued approval. The same dynamic has played out for eugenol and thymol. These substances are not being removed because they are uniquely dangerous, they are being removed because no one paid for them to stay.

That distinction matters for consumer communication, but it does not change the regulatory outcome: products using them as active biocidal substances will need to be reformulated or withdrawn.

Which Products Are Affected?

The most directly impacted products are in two BPR product types:

Affected product lines include a significant portion of the premium "natural repellent" segment: plant-based sprays, essential-oil repellent bands and clips, citronella-adjacent formulations that blend geraniol with other botanical extracts, and various private-label lines sold by pharmacies, outdoor retailers, and eco-product stores across Europe.

A fourth natural ingredient, lavandin oil, is following a similar trajectory, with the deadline for industry support set at 26 August 2026. Its regulatory future is similarly uncertain.

What Is Still EU-Legal?

The EU currently maintains a list of fully approved active substances for insect repellents. As of today, these are:

| Active Substance | Common Name | Notes | |---|---|---| | DEET (N,N-Diethyl-meta-toluamide) | DEET | EU max 20% for general use; >20% requires specific authorisation | | Icaridin (Saltidin®, Picaridin) | Icaridin | Widely considered the safest synthetic repellent for children and pregnant women | | IR3535 (Ethyl butylacetylaminopropionate) | IR3535 | Merck-developed; approved across EU; good skin tolerability | | Citriodiol™ (p-Menthane-3,8-diol) | PMD, oil of lemon eucalyptus | Plant-derived but fully reviewed and approved |

If your repellent uses one of these four actives as its primary ingredient, it is EU-authorised and can continue to be placed on the market. If it uses geraniol, eugenol, or thymol as the stated active substance, it falls into the category that is now losing its authorisation pathway.

How to Check Your Product

The simplest approach is to read the active substance declaration on the packaging. EU-regulated biocidal products are required to list their active substances. If the product does not list an active substance at all, it may not be authorised as a biocidal product, which raises separate questions about whether its efficacy claims are substantiated.

Look for the phrase "Biocidal Product" or a biocidal product registration number on the label. Products legally authorised under the BPR carry this marking. Products that merely contain plant extracts but make no biocidal efficacy claims may be classified differently, as cosmetics, for example, but they also cannot legally claim to repel mosquitoes or provide protection against bites.

When in doubt, check the ECHA Product Register.

What This Means for the Wider Market

Today's deadline accelerates a consolidation that has been underway in the EU repellent market for several years. The premium "natural repellent" segment, which grew rapidly through the 2010s on the back of consumer demand for plant-based alternatives, is facing a structural challenge: the ingredients that made its marketing compelling are losing their legal pathway.

This creates pressure in a few directions. Some manufacturers will reformulate around Citriodiol™, the one plant-derived active that has successfully completed the BPR review and is genuinely EU-approved. Others will migrate their products toward DEET or Icaridin and reclassify their positioning. Some will exit the repellent category altogether.

For consumers, the message is straightforward: a product marketed on the basis of geraniol or eugenol is no longer backed by EU regulatory review of that ingredient. The EU's position is not that these compounds are certainly dangerous, it is that the evidence has not been assembled to demonstrate that they are safe and effective to the standard the regulation requires. Given that the purpose of a repellent is to protect you from mosquito-borne disease, that gap matters.

A Different Approach to the Problem

Mosticare builds mosquito protection around a completely different principle: physical barrier. Our products, screens, nets, and structural protection systems, prevent mosquitoes from reaching you without using any biocidal active substance at all. There is no active ingredient to approve, no review cycle to navigate, no risk of reformulation. Physical barriers work by mechanical exclusion, not chemical repulsion, and the EU has no plans to regulate geometry.

This is not a coincidence of design. Physical protection is the most durable and broadly applicable form of mosquito defence precisely because it operates outside the chemical regulatory cycle. As active-substance approvals become harder to obtain and maintain, the reliability of physical barriers becomes more valuable.
