Sunscreen is the last place you expect to run into a fragrance ingredient. But oxybenzone, the filter named on the bottle, is used in fragrance formulations too. You may also see it listed as benzophenone-3 (BP-3). The industry’s own panel called it safe, and then left the sunscreen out of its math. Here’s what the graded research says, who said it, and what is still open.
Evidence key Strong Moderate Weak How we grade
The industry called it safe. Read what it left out.
The cosmetics industry runs a safety panel that reviews its own ingredients. Here’s what that panel concluded about oxybenzone.
The cosmetics industry's own safety panel (CIR, funded by the Personal Care Products Council) concluded in 2021 that Benzophenone-1, -2, -3, -4, -5, -6, -8, -9, -10, -11 and -12 are 'safe' in cosmetics at their present concentrations of use, including Benzophenone-3 (oxybenzone) used as a light stabilizer or fragrance-formulation ingredient at up to 0.5%. Moderate evidence. CIR 2021 Benzophenones Industry-funded
Read the scope before you trust the headline.
The cosmetics industry's 2021 safety review of benzophenone-3 (oxybenzone) explicitly covers only its use as a light stabilizer/product-protectant at up to 0.5% concentration — not its use as an active sunscreen ingredient at up to 6%, which is regulated separately by the FDA under 21 CFR 352 and was not included in this safety review's concentration-of-use survey. Strong evidence. CIR 2021 Benzophenones Industry-funded
So the “safe” verdict doesn’t cover the sunscreen use at all. This article is not an argument to stop using sunscreen. It’s an argument for asking who checked what.
Where else it turns up
It isn’t confined to the sunscreen aisle.
Benzophenone-3 (oxybenzone) is used in fragrance formulations at concentrations up to 0.5%, and separately in lipstick (up to 0.5%, incidental ingestion) and bath soaps/detergents (up to 0.5%, mucous-membrane contact), per the cosmetics industry's own 2021 concentration-of-use data. Strong evidence. CIR 2021 Benzophenones Industry-funded
Benzophenone-3 is used in baby lotions, oils, and creams (not powder) at concentrations up to 0.25%, according to the cosmetics industry's own 2021 concentration-of-use survey. Strong evidence. CIR 2021 Benzophenones Industry-funded
For reference, here is the ceiling US federal regulation sets for sunscreens.
US federal regulation (21 CFR 352.10) permits oxybenzone (benzophenone-3) as a sunscreen active ingredient at up to 6 percent. Strong evidence. 21 CFR 352.10 (2023 ed.)
What regulators said
The US first. A proposal is not a ban, and our research file cannot show what happened to this one afterward.
In a proposed order issued September 24, 2021, the US Food and Drug Administration proposed that sunscreens containing oxybenzone (benzophenone-3) are not generally recognized as safe and effective (GRASE), because the evidence in the record is inadequate. Strong evidence. FDA proposed order OTC000008 (2021)
Europe took a different route, and it didn’t stop at a proposal. First came the safety committee’s opinion.
In its March 2021 opinion, the EU's independent cosmetics safety committee (SCCS) concluded that benzophenone-3 (oxybenzone) at 6% is not safe as a UV filter in body-cream, propellant-spray, or pump-spray sunscreens, but is safe at 6% in face cream, hand cream, and lipstick. Strong evidence. SCCS 2021 (BP-3 opinion)
Then came the law, with different ceilings for different parts of your body.
EU law caps benzophenone-3 (oxybenzone) as a UV filter at 2.2% in body products, including propellant and pump sprays, against 6% in face, hand and lip products (excluding sprays) and 0.5% in other products. Strong evidence. Commission Regulation (EU) 2022/1176, Annex VI entry 4 (OJ L 183, 8.7.2022)
Note what the EU did not do.
The EU did not ban benzophenone-3 or octocrylene in 2022; both stay legal at reduced maximum concentrations. Strong evidence. Commission Regulation (EU) 2022/1176, recital 2
What gets into the body
Two FDA trials measured blood levels. Both used heavy, repeated application, so read the caveats.
In an FDA-run randomized trial of 24 healthy adults applying commercial sunscreens under maximal labeled use (2 mg/cm2 over 75% of the body, 4 times a day, for 4 days), oxybenzone reached a geometric mean peak blood concentration of 169-210 ng/mL, roughly 340 to 420 times the FDA's own 0.5 ng/mL threshold for requiring additional cancer and reproductive-toxicology studies, and was still above 20 ng/mL a full three days after the last application. Moderate evidence. Matta 2019
In a second FDA trial of 48 healthy adults, all 6 tested sunscreen active ingredients — avobenzone, oxybenzone, octocrylene, homosalate, octisalate, and octinoxate — exceeded the FDA's 0.5 ng/mL systemic-absorption threshold after just a single application on day 1, not only after days of repeated maximal use. Moderate evidence. Matta 2020
Studies of ordinary people point the same way: it turns up in people’s bodies.
The EU committee's opinion notes benzophenone-3 has been found in human urine, blood, breast milk, and placental tissue; it cites a NHANES finding of BP-3 in 97% of 2,517 US urine samples, and a pregnant-women median urinary level (0.47 uM) about 3.4 times the non-pregnant median (0.137 uM) in one study (Majhi 2020). Moderate evidence. SCCS 2021 (BP-3 opinion)
One short product-swap study measured urine levels, not health effects, and it covered several chemical groups at once.
When 100 teenage girls swapped their usual personal care products for ones labeled free of phthalates, parabens, triclosan, and oxybenzone for just 3 days, levels of these chemicals in their urine fell by 27-45%. Moderate evidence. Harley 2016
In that study, the urine levels fell after the swap. That’s the part you can act on.
When it meets your skin
The EU committee confirmed that benzophenone-3 can cause photoallergic skin reactions, citing the European photo-patch test task force ranking it the second most frequent photo contact allergen among UV filters, plus one reported anaphylaxis case. Moderate evidence. SCCS 2021 (BP-3 opinion)
FDA says oxybenzone is a contact allergen for people with pre-existing skin conditions and a photoallergen for people with photosensitivity, and it would consider requiring allergy labeling if the missing data supported GRASE. Moderate evidence. FDA proposed order OTC000008 (2021)
The next finding comes from the manufacturer’s own studies, so weigh it that way.
A pooled analysis of 64 unpublished studies commissioned by a sunscreen maker found that about 1 in 400 healthy adults (48 of 19,570) had any possible irritation or allergic reaction to oxybenzone sunscreens under exaggerated patch-test conditions, and oxybenzone itself was confirmed as the cause in only 8 people. Moderate evidence. Agin 2008 (oxybenzone HRIPT) Industry-funded
Hormones: inconclusive is not the same as cleared
The EU committee called the evidence that benzophenone-3 disrupts hormones 'inconclusive, and at best equivocal' across computer-modeling, cell, and animal studies, and asked for further investigation; it did not conclude that BP-3 is an endocrine disruptor. Strong evidence. SCCS 2021 (BP-3 opinion)
Two sunscreen ingredients, oxybenzone (benzophenone-3) and homosalate, blocked the male hormone receptor in human cells, at roughly the potency of the pesticide metabolite p,p'-DDE. Moderate evidence. Schlumpf 2004
FDA says oxybenzone was detected in human breast milk, amniotic fluid, urine and blood plasma, and that high maternal urinary levels were associated with birth-weight changes in one biomonitoring study, which FDA calls "inconclusive" evidence of endocrine effects in humans. Moderate evidence. FDA proposed order OTC000008 (2021)
What you can do
This article is not a reason to stop using sunscreen. It is a reason to read the label, and to ask for more.
- Look for the name on labels. Our label decoder and the benzophenone-3 page explain the spellings.
- Ask a pharmacist or dermatologist about sunscreen options before you change your sun protection.
- Tell brands and lawmakers you want ingredients named, not hidden behind “fragrance.” Here’s how.
- Read related evidence on labels, skin absorption, and hormone claims: the fragrance loophole, what your skin absorbs, and fragrance and hormones.
- You can also look products up on EWG Skin Deep.
