Diethylhexyl Butamido Triazone

What Diethylhexyl Butamido Triazone is & what it does

A photostable UVB filter (Iscotrizinol / Uvasorb HEB) with strong absorption, used to raise SPF efficiently. It is substantive and water-resistant, making it useful in beach and sport formulas.

What is Diethylhexyl Butamido Triazone and what does it do in sunscreen?

Diethylhexyl Butamido Triazone is a UV filter, also sold under the names Iscotrizinol and Uvasorb HEB. It mainly absorbs UVB light, the band most responsible for sunburn, and it does so strongly, so it helps raise SPF efficiently without needing a lot of material. It is photostable, meaning it holds up well in sunlight, and it tends to stay on the skin, which makes it useful in water-resistant beach and sport sunscreens.

Is Diethylhexyl Butamido Triazone safe?

Yes. It is an approved sunscreen filter used in Europe and many other markets, where UV filters are tightly regulated and only cleared after safety review. It is a large molecule that stays on the skin's surface rather than absorbing readily, and it is not a common cause of irritation. Note that it is not on the list of filters approved for use in the United States, which is why you mostly see it in European, Asian, and Australian products.

Is Diethylhexyl Butamido Triazone a chemical or mineral filter?

It is an organic, sometimes called chemical, UV filter rather than a mineral one. It works by absorbing UV energy within its own molecule rather than by sitting on top of skin like zinc oxide or titanium dioxide. Because it is colorless and leaves no white cast, it is often paired with other modern filters to build broad, cosmetically elegant protection.

Does Diethylhexyl Butamido Triazone clog pores?

Generally no. It is not flagged as comedogenic, and it is a large, substantive molecule used to deliver UV protection rather than a pore-clogging oil. As with any sunscreen, the overall feel on the skin depends more on the emollients and the total filter load than on this one ingredient.

What else is Diethylhexyl Butamido Triazone called?

"Diethylhexyl Butamido Triazone" is the INCI name on the label. It is also marketed under the trade name Uvasorb HEB and the name Iscotrizinol. All three refer to the same UVB-absorbing filter.
