Cosmate®AVB,Avobenzone,Butyl Methoxydibenzoylmethane. Ndizochokera ku dibenzoyl methane. Mitundu yambiri ya kuwala kwa ultraviolet wavelengths imatha kuyamwa ndi avobenzone. Imapezeka m'ma sunscreens ambiri omwe amapezeka pamalonda. Zimagwira ntchito ngati sunblock. Choteteza chapamwamba cha UV chokhala ndi sipekitiramu yotakata, avobenzone imatchinga mafunde a UVA I, UVA II, ndi UVB, kuchepetsa kuwonongeka komwe kuwala kwa UV kumatha kuwononga khungu.
Avobenzone (BMDM, Butyl methoxydibenzoylmethane) ndi mankhwala oteteza ku dzuwa omwe amapereka chitetezo chochuluka ku cheza cha UVA. Avobenzone imatenga zonse za UV-(380-315 nm zomwe zimagwirizanitsidwa ndi kuwonongeka kwa khungu kwa nthawi yayitali) ndi UV-B (315-280 nm yomwe imayambitsa kutentha kwa dzuwa). Avobenzone amadziwika kuti ndi imodzi mwazinthu zothandiza kwambiri zoteteza dzuwa.
