Avobezone yog lub zog hluavtaws ultraviolet. Nws yog qhov zoo UV-A (GG gt; 320nm) hom ultraviolet nqus, uas tuaj yeem tiv thaiv tag nrho cov kab tawm (320 ～ 400nm) ntawm UVA, thiab yog qhov kev ua tau zoo ntawm cov roj-soluble UVA lim, sib xyaw nrog lwm cov UVB tiv thaiv hnub ci, tuaj yeem muab tag nrho UVA thiab UVB tiv thaiv, siv los tiv thaiv kev yees duab los ntawm daim tawv nqaij ua cancer.

Avobenzone (cov npe ua lag luam Parsol 1789, Milestab 1789, Eusolex 9020, Escalol 517, Neo Heliopan 357 thiab lwm tus, INCI Butyl Methoxydibenzoylmethane) yog cov roj-cov tshuaj tiv thaiv cov khoom siv hauv tshuaj pleev thaiv hnub kom nqus tau cov hnub ci UVA txoj sab ci tag nrho. Nws yog ib tug dibenzoylmethane derivative. Avobenzone tshwm sim hauv cov av hauv xeev yog kev sib xyaw ua ke ntawm cov ntaub ntawv enol thiab keto, nyiam qhov chelated enol. Daim foos enol no ruaj khov los ntawm intramolecular hydrogen-tsevneeg hauv the-diketone. Nws lub peev xwm los nqus ultraviolet lub teeb dhau qhov dav dua ntawm cov yoj yoj qhov ntev dua ntau lwm cov neeg tiv thaiv tshav ntuj tau ua rau nws siv nyob rau hauv ntau cov kev npaj muag khoom lag luam ua" dav spectrum" duab hnub ci. Avobenzone muaj qhov siab ntau tshaj plaws ntawm 357nm.
