Butyl Methoxydibenzoylmethane

anti-ageing

overview

Butyl methoxydibenzoylmethane, also known as avobenzone, is a synthetic sunscreen ingredient that provides protection against both UVA and UVB rays. It is globally approved and has been rigorously tested for safety and efficacy. It 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.

benefits

Anti-Aging: Butyl methoxydibenzoylmethane helps protect the skin from UVA rays, which can cause premature aging. UV Protection: Butyl methoxydibenzoylmethane absorbs UV light over a wide range of wavelengths and converts it into less damaging infrared radiation (heat).

concerns

Butyl methoxydibenzoylmethane can become unstable when exposed to UV light, so it is important to reapply sunscreen frequently during long periods of time outdoors.

additional info

Butyl methoxydibenzoylmethane is also known under the name Avobenzone. It increases the stability of chemical hair colors. Prevents natural- and synthetic hair dyes from fading in the sun. It is restricted in cosmetics in Japan due to concentration limits. It has low potential to absorb into the skin. It is not suspected to be an environmental toxin or bioaccumulative. Avobenzone is not photostable and degrades in sunlight, losing 36% of its UV-absorption capacity after just one hour of sunlight. The cosmetic industry is trying to solve the problem by combining avobenzone with other UV filters that enhance its stability (like octocrylene, Tinosorb S or Ensulizole) or by encapsulating it. However, neither solution is perfect. The combination of avobenzone with mineral sunscreens (titanium dioxide and zinc oxide) is not recommended, as avobenzone becomes unstable when combined with mineral sunscreens. Avobenzone is associated with causing photocontact dermatitis in some individuals. It may also produce classic allergic contact dermatitis.
