Description
Ethylhexyl Triazone (chemical name: Octyl Triazone) is a highly efficient, oil-soluble organic UVB filter used in modern sunscreen formulations for maximum sun protection. Recognized as one of the most effective UVB absorbers available, it offers extremely high absorption capacity in the UVB range (280–320 nm), helping to prevent sunburn and UV-induced skin damage.
This filter is exceptionally photostable, meaning it retains its protective ability even after prolonged exposure to sunlight. Its high molar extinction coefficient allows formulators to achieve strong UVB protection with lower usage levels, improving the texture and feel of the final product. Often used in combination with UVA filters such as Avobenzone, Bisoctrizole, or Bemotrizinol, Ethylhexyl Triazone contributes to broad-spectrum protection by addressing the UVB portion of the spectrum, while its partners handle UVA rays.
Thanks to its water-resistant nature, it is well-suited for high-performance sunscreens designed for swimming, sports, and extended outdoor activities. It blends smoothly into creams, lotions, gels, and sprays without leaving a greasy finish or white cast, making it suitable for both daily wear and specialized sun care products.
Ethylhexyl Triazone is generally well tolerated by the skin and has low dermal penetration, minimizing the risk of irritation. It also helps stabilize and enhance the performance of other UV filters, improving the overall effectiveness of the formulation.
In terms of regulatory approval, Ethylhexyl Triazone is permitted for use in the European Union (up to 5%), Australia, Japan, and several other markets, but is not yet approved by the FDA for sunscreens in the United States.
With its high UVB absorption power, excellent stability, and compatibility with other UV filters, Ethylhexyl Triazone remains a go-to choice for creating long-lasting, effective, and consumer-friendly sunscreen products.
