Benzophenone-3 (Oxybenzone)
What is Benzophenone-3 (Oxybenzone)?
Benzophenone-3, also known as Oxybenzone, is a chemical compound used as a sunscreen agent. It works by absorbing harmful ultraviolet (UV) rays, thereby protecting the skin from damage. It is synthetically produced through chemical processes.
It's primarily used in sun protection products, as well as some fragrances, due to its ability to stabilize and protect against UV light. Health concerns include potential absorption through the skin and hormonal disruption, leading to regulatory scrutiny in some regions.
When you see Benzophenone-3 on a label, it indicates the product has ingredients designed to filter UV light and protect against sun damage. However, consider checking if the product has been certified as safe for use by relevant authorities.
Commonly found in: sunscreens, fragrances, moisturizers, lip balms, hair care products
What to watch
- Studies suggest it may absorb into the bloodstream and potentially cause hormonal disruptions.
- It has been detected in human breast milk, urine, and blood, raising concerns about exposure.
Benefits
- Provides effective protection against harmful UVA and UVB rays.
Oxybenzone is approved for use in sunscreens up to 6% concentration, but the FDA is evaluating its safety due to potential health risks.
Research has shown both UV protection benefits and potential for hormonal disruption, leading to mixed views on safety.
Benzophenone-3 is synthetic and not derived from animals, so it is considered vegan-friendly.

Scout's take
Chemical UV filter and one of the most studied endocrine disruptors in cosmetics. Mimics estrogen, blocks androgen receptors, detected in 96%+ of US urine samples. Banned in Hawaii, Key West, Aruba, and Palau for reef toxicity. Banned in EU as a fragrance additive (allowed only at sunscreen-active concentrations). No legitimate use in a leave-on fragrance spray.
