Cosmate®AVB ,Avobenzone,Butyl Methoxydibenzoylmethane. Waa nooc ka mid ah methane dibenzoyl. Mawjadaha dhaadheer ee iftiinka ultraviolet ee ballaaran waxaa nuugi kara avobenzone. Waxay ku jirtaa muraayado badan oo ballaaran oo qorraxdu kuwaas oo ganacsi ahaan la heli karo. Waxay u shaqeysaa sidii xannibaadda qorraxda. Ilaaliyaha UV ee jirka oo leh muuqaal ballaadhan, avobenzone wuxuu xannibaa UVA I, UVA II, iyo UVB dhererka hirarka, taasoo yaraynaysa waxyeelada ay fallaaraha UV u geysan karaan maqaarka.
Avobenzone (BMDM, Butyl methoxydibenzoylmethane) waa kiimiko muraayad cadceed ah oo bixisa difaac ballaaran oo ka dhan ah fallaadhaha UVA. Avobenzone waxay nuugtaa labadaba UV-(380-315 nm taas oo la xiriirta dhaawaca maqaarka muddada dheer) iyo UV-B (315-280 nm oo sababa gubasho) fallaadhaha. Avobenzone waxaa loo yaqaanaa mid ka mid ah walxaha ugu waxtarka badan ee muraayadda qorraxda.
