Avobenzone
Avobenzone(BMDM, Butyl methoxydibenzoylmethane) ke k'hemik'hale ea skrine ea letsatsi e fanang ka tšireletso e pharaletseng khahlanong le mahlaseli a UVA.Avobenzone e monya ka bobeli UV-(380-315 nm e amanang le tšenyo ea nako e telele ea letlalo) le UV-B (315-280 nm e bakang ho chesoa ke letsatsi) mahlaseli. Avobenzone e tsejoa e le e 'ngoe ea metsoako e sebetsang ka ho fetisisa e sireletsang letsatsi.
