Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine

What Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine is & what it does

A modern broad-spectrum filter (Tinosorb S) that is highly photostable and covers both UVB and UVA. It also stabilizes other filters like avobenzone, which is why formulas built around it tend to hold protection well. Approved in Europe and much of the world, but not in US over-the-counter sunscreens.

What is Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine (Tinosorb S)?

It is Tinosorb S, also called bemotrizinol (and sold as Parsol Shield), a modern, highly photostable chemical UV filter that covers both UVB and UVA in a single molecule. It also helps stabilise less stable filters like avobenzone.

Is Tinosorb S a UVA or UVB filter?

Both. It is a broad-spectrum filter that absorbs strongly across UVB and UVA, part of why it is so valued in well-formulated sunscreens.

Is Tinosorb S safe?

It is regarded as one of the safer, more stable filters, with very low skin penetration and a low irritation rate, and is long approved across the EU and Asia. In June 2026 the US FDA also cleared it (as bemotrizinol), its first new sunscreen filter in about 20 years, so it is now allowed in US sunscreens too.

Is Tinosorb S natural?

No, Tinosorb S (bemotrizinol) is a modern synthetic UV filter, designed in a lab for broad-spectrum, photostable protection. It does not occur in nature, and it is one of the better-regarded filters on safety and stability.

Is Tinosorb S safe to use during pregnancy?

Tinosorb S has very low skin penetration and no proven pregnancy concern, which is part of why it is one of the better-regarded modern filters. As with any chemical filter, some people still prefer a mineral sunscreen while pregnant for extra reassurance. Your doctor can advise on your situation.
