Product description

AakoSun AVB is better known as Butyl Methoxydibenzoylmethane. It is an synthetic, oil-soluble sun filter that absorbs both UV-A and UV-B radiation. Butyl Methoxydibenzoylmethane is being used in a wide range of cosmetic products to provide an appropriate Sun Protection Factor (SPF) in sunscreens or to protect cosmetics against UV radiation.

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

In America max. 3% and in Europe max. 5%.

Butyl Methoxydibenzoylmethane is particularly suitable for water-repellent and water-resistant formulations, as it is hydrophobic and oil-soluble. It is globally the only available chemical sunscreen that provides proper UV-A protection. This makes Butyl Methoxydibenzoylmethane the gold standard of UV-A protection.

Butyl Methoxydibenzoylmethane is also known under the name Avobenzone.



  • Has the ability to absorb UV light over a wide range of wavelengths and convert it into less damaging infrared radiation (heat).
  • It increases the stability of chemical hair colors.
  • Prevents natural- and synthetic hair dyes from fading in the sun.
