Sunscreen UV Filters: Which Are Approved in the US vs the EU

If you have ever wondered why a sunscreen you loved in Europe isn't sold in the United States, the answer is regulatory, not chemical. The EU approves roughly 30 UV filters for cosmetic use; the US OTC sunscreen monograph allows about 16, and the FDA has signalled it considers only two of them — the mineral filters — clearly safe and effective with current data. The modern organic filters that make many European sunscreens cosmetically elegant and strong on UVA simply aren't legal to sell over the counter in the US.

For a brand formulating sun care, this is one of the hardest market gaps to design around: a single global SPF formula is usually impossible. Here's exactly which filters each market allows, and why.

Sunscreen is a cosmetic in the EU and a drug in the US

The whole gap flows from one fact: the two markets regulate sunscreen under completely different legal frameworks.

European Union: sunscreen is a cosmetic under Regulation (EC) No 1223/2009. Permitted UV filters are listed in Annex VI, and new filters are added by the Commission following a safety opinion from the SCCS. The list updates regularly.
United States: sunscreen is an OTC drug. Active filters must be recognized as "Generally Recognized As Safe and Effective" (GRASE) under the OTC monograph (21 CFR Part 352). Adding a filter requires the full drug-evidence bar — which, in practice, has frozen the US list for decades.

That difference in burden of proof — cosmetic safety opinion vs. drug-grade GRASE evidence — is the entire story. It's the same reason salicylic acid can be a cosmetic in the EU and an OTC drug in the US (see our banned ingredients guide for more cross-market splits like this).

UV filter approval by market

The filters brands ask about most, and where each is approved. "Mineral" filters scatter/reflect UV; "organic" (chemical) filters absorb it.

UV filter (INCI / common)	Type	US (OTC)	EU (Annex VI)
Zinc Oxide	Mineral	Approved	Approved
Titanium Dioxide	Mineral	Approved	Approved
Avobenzone	Organic (UVA)	Approved	Approved
Octinoxate	Organic (UVB)	Approved*	Approved
Octisalate	Organic (UVB)	Approved	Approved
Homosalate	Organic (UVB)	Approved	Approved (restricted)
Octocrylene	Organic	Approved	Approved
Oxybenzone	Organic	Approved*	Approved (restricted)
Bemotrizinol (Tinosorb S)	Organic (broad)	Not approved	Approved
Bisoctrizole (Tinosorb M)	Organic (broad)	Not approved	Approved
Ecamsule (Mexoryl SX)	Organic (UVA)	Limited†	Approved
Drometrizole Trisiloxane (Mexoryl XL)	Organic (broad)	Not approved	Approved

*Octinoxate and oxybenzone are federally approved in the US but banned from sale in Hawaii, Key West, the US Virgin Islands and other jurisdictions under reef-protection laws. †Ecamsule is permitted in the US only via specific approved (NDA) products, not the general OTC monograph. EU "restricted" entries carry concentration limits in Annex VI. Always verify against the current monograph/Annex for your product — see sources.

Why the US list is frozen

The US OTC sunscreen monograph hasn't added a new filter in decades. Congress passed the Sunscreen Innovation Act in 2014 specifically to clear a backlog of modern filters (Tinosorb, the Mexoryls, and others) that had been used safely in Europe for years. But rather than approving them, the FDA requested additional safety data — particularly on systemic absorption — for essentially all organic filters.

In its 2019 proposed rule (carried forward under the CARES Act monograph reform), the FDA proposed that only zinc oxide and titanium dioxide are GRASE (Category I) on current evidence; two older filters (PABA, trolamine salicylate) are not GRASE; and the remaining ~12 organic filters need more data before a determination. The net effect: the modern broad-spectrum organic filters available in the EU remain unavailable for US OTC sunscreens.

What EU formulators can do that US ones can't

Access to Tinosorb S/M and the Mexoryls is why European sunscreens are often described as more elegant and better at UVA protection:

Stronger, more stable UVA coverage. Avobenzone — the main UVA filter available in the US — is photo-unstable and must be stabilized. Tinosorb and the Mexoryls deliver broad, photostable UVA protection more easily.
Better aesthetics. Modern filters allow lighter textures and less white cast at high SPF, which is hard to achieve with the US-available palette, especially in mineral-heavy formulas.
Higher labelled UVA ratings. The EU's UVA-PF requirement (UVA protection at least one-third of the SPF, the "UVA in a circle" mark) is easier to hit with modern filters.

The reef-safe layer (US state and territory bans)

On top of the federal picture, a growing set of jurisdictions ban the sale of sunscreens containing oxybenzone and octinoxate to protect coral reefs — even though both are federally legal:

Hawaii (Act 104, effective 2021)
Key West, Florida
US Virgin Islands
Palau, Bonaire, Aruba and others internationally

A US sunscreen brand can be fully FDA-compliant and still illegal to sell in Honolulu. If you distribute nationally, the practical move many brands make is reformulating away from oxybenzone/octinoxate entirely.

Formulating sun care across markets

Because the filter lists don't overlap cleanly, a single global SPF SKU is usually not feasible. The common approaches:

Mineral-only base. Zinc oxide and titanium dioxide are approved in both the US and EU, so an all-mineral formula travels furthest — at the cost of texture/white-cast tradeoffs.
Region-specific formulas. A US version on the OTC-approved palette and an EU version using modern filters. Most common for serious sun-care brands.
Avoid reef-banned filters regardless of market, to keep US distribution unrestricted.

Frequently asked questions

Why can't I buy European sunscreen in the US?

Because most European sunscreens use UV filters (Tinosorb, Mexoryl) that aren't approved under the US OTC drug monograph. Selling them in the US without FDA approval would make them unapproved new drugs.

Are mineral sunscreens approved everywhere?

Zinc oxide and titanium dioxide are approved in both the US and EU. They're the most portable choice for a multi-market formula. Note the EU restricts the nanoparticle form of titanium dioxide in inhalable (loose powder) applications.

Is the US going to approve modern filters?

The filters have been under FDA review for years. As of 2026 the FDA has requested additional safety data rather than approving them, so there's no confirmed timeline. Don't formulate a US product assuming near-term approval.

What does "reef-safe" legally mean?

There's no federal definition. In practice it refers to sunscreens free of oxybenzone and octinoxate, which several US states/territories and other countries ban from sale to protect coral.
