What is Diethylhexyl butamido triazone?
Diethylhexyl butamido triazone (CAS 154702-15-5), sold under the trade name Uvasorb HEB, is an oil-soluble UVB filter used in sunscreen and photoprotection formulations.

- Often combined with UVA filters for broad-spectrum SPF
- Anhydrous formulations, emollients and W/O emulsions
- Color cosmetics: tinted moisturizers and foundations
