AAKO name AakoSun BEMT

Product description

AakoSun BEMT is better known as Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine. It is an organic, oil-soluble sun filter. Absorbs both UV-A and UV-B rays at wavelengths from 280 to 400nm, with peak protections at about 310 and 345nm. Only small concentrations are required to achieve a high Sun Protection Factor (SPF) and UV-A Protection Factor (UVAPF). Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine is not significantly absorbed into the skin, barely leads to skin irritation and does not appear to have hormonal effects.

Approved for the use in sun care preparations in many countries worldwide.

  • In Europe max. 10%. Waiting for FDA approval, so currently not available in the USA.

Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine is also known under the name Bemotrizinol.



  • Most effective UV absorber available, as measured by SPF and UVAPF.
  • Super photostable UV filter. Only loses 10% of it’s SPF protection ability in 25 hours.
  • Ideal to stabilize other less stable sunscreen agents, like AakoSun AVB. Combinated formulations like these do not degrade and don’t lose effectiveness on exposure to light.
