Bemotrizinol (INN[1][2]/USAN[3]名称;INCN名称,bis-ethylhexyloxyphenol methoxyphenyl triazine)是一种油溶性的有机化合物,添加于防晒乳中吸收紫外线。BASF与 Ashland Inc分别以商品名 Tinosorb S及Escalol S推出上市。Bemotrizinol是广域性(宽频)的紫外线吸收剂,能吸收 UVB以至UVA,它的吸收顶峰有两个,分别位于波长 310及 340奈米处。[4] 其光稳定性极高,即使施予 50MEDs(minimal erythema doses,最小晒红剂量,其数值因人而异。例如某人照射 20分钟的紫外线皮肤即出现红肿现象,20分钟则为其最小晒红剂量)之紫外线,仍能保有 98.4%的量不被分解, 与其他防晒剂例如阿伏苯宗混合还能抑制它们产生光分解反应(photodegradation)[5]
Bemotrizinol不受美国 FDA核可。2000年后陆续获得欧盟与澳大利亚等核准。[6] [7] [8] 与其他有机(化学)防晒剂不同的是,它于活体外实验(In vitro)之中不会呈现出雌激素效应。[9]
