Ethylhexyl Triazone (EHT) is an oil-soluble UV filter used primarily in sunscreens and skincare products. It provides high-efficiency broad-spectrum protection by absorbing UVB radiation. EHT offers excellent photostability, making it ideal for long-lasting sun protection, even under harsh sunlight conditions. It is commonly used in sunscreen formulations for effective sun shielding. The structure contains a 1,3,4-oxadiazole ring, which is a heterocyclic compound with nitrogen and oxygen atoms, and a 2-ethylhexyl group attached to it.

Ethylhexyl Triazone is a broad-spectrum UV filter commonly used in sunscreen formulations, providing high UVB absorption while being photostable
It is approved for use in sunscreens in multiple regions, including EU (Annex VI of the EU Cosmetic Regulation), FDA, and Asian markets, with specific concentration limits depending on the country’s regulations.
Ethylhexyl Triazone is a highly effective UVB filter with strong photostability and excellent water resistance, making it ideal for long-lasting broad-spectrum sunscreen formulations. It provides high UV absorption, allowing lower concentrations to achieve strong sun protection.
Solubility: Oil-soluble, compatible with various organic UV filters. Recommended Use Levels: Typically up to 5% in sunscreen formulations. Synergistic Effects: Works well when combined with Tinosorb S, Avobenzone, and Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine (BEMT) for broad-spectrum UVA & UVB protection. Preferred Formulations: Suitable for emulsions (O/W and W/O), anhydrous formulations, and oil-based sunscreens.
No, it is oil-soluble and is typically formulated in oil-based emulsions for cosmetic and dermatological applications.
