Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine

Bis-ethylhexyloxyphenol methoxyphenyl triazine (also known as Tinosorb S or Bemotrizinol) is a synthetic UV filter that delivers broad-spectrum sun protection due to its ability to absorb UVA and UVB rays. Like other UV filters, it is dually considered an anti-aging ingredient in the regard that it helps ward off visible signs of accelerated skin aging triggered by sun exposure. Bis-ethylhexyloxyphenol methoxyphenyl triazine is noted for being highly effective at low concentrations, which is one of the reasons it is a popular choice when high SPF levels are desired. It is also praised for having excellent photostability and is known to help improve the stability of other sunscreen agents. Bis-ethylhexyloxyphenol methoxyphenyl triazine has been available in many countries around the world for years, but only gained U.S. Food and Drug Administration in June 2026. The U.S.-approved use has a maximum level of 6%. In all other global markets where this filter has gained approval, it’s permitted up to 10% concentration in sunscreen formulations. Was the U.S. FDA being too conservative? After all, this filter has been used in the European Union since 2000! It selected 6% as the cap because that is the highest concentration for which it had sufficient *U.S.-specific* safety and systemic exposure data to make a GRASE (Generally Recognized as Safe and Effective) determination under its OTC (over the counter) drug framework. Bis-ethylhexyloxyphenol methoxyphenyl triazine comes as a light yellow powder in its raw material form and is oil soluble.
