干扰正常内分泌。
Extensive research has shown that a number of UV filters frequently used in the formulation of commercial sunscreens, such as 4 MBC, octyl methoxycinnamate, oxybenzone (benzophenone-3), octyl-dimethyl-PABA and octinoxate, possess endocrine activity. Endocrine disruptors are chemicals that interfere with endogenous hormone action and/or production. These have been implicated in the development of a number of diseases in both males and females, including cancer of the mammary glands and reproductive organs, as well as the abnormal development of the male reproductive system. In one study, the application of three active ingredients commonly found in sunscreens (oxybenzone, 4-MBC and octinoxate) for one week led to a drop in testosterone and estradiol levels in men. More worrying is that these chemicals have been found in breast milk at concentrations known to have oestrogenic effects.

甲氧基肉桂酸辛酯 (Octinoxate)
作用是以吸收阳光中的中波紫外线(UVB)，保护皮肤免于其伤害，是目前最常广泛使用的 UVB 防晒乳。甲氧基肉桂酸辛酯对皮肤刺激性小，但却会扰乱荷尔蒙、造成皮肤老化，并产生自由基破坏皮肤细胞。

即便在低剂量的情况下，会刺激珊瑚的共生藻体内的病毒攻击共生藻，间接使珊瑚白化甚至死亡，而共生藻死亡后的病毒被释入海水后，导致周边海水病毒浓度增加，提高了其他珊瑚体内共生藻的感染率。

Regarding safety, there are also some concerns around Octinoxate. In vitro (made in the lab not on real people) and animal studies have shown that it may produce hormonal (estrogen-like) effects. Do not panic, the studies were not conducted under real life conditions on real human people, so it is probably over-cautious to avoid Octinoxate altogether. However, if you are pregnant or a small child (under 2 yrs. old), choose a physical (zinc oxide/titanium dioxide) or new-generation Tinosorb based sunscreen, just to be on the super-safe side. :)
Overall, Ethylhexyl Methoxycinnamate is an old-school chemical sunscreen agent. There are plenty of better options for sun protection today, but it is considered "safe as used" (and sunscreens are pretty well regulated) and it is available worldwide (can be used up to 10% in the EU and up to 7.5% in the US).

Coral safe? No, may also potentially affect fish
Found in chemical sunscreens
Octinoxate is a common and potent UVB absorber, meaning it’s effective for sun damage prevention. Combined with avobenzone, they can both provide great broad-spectrum protection against burns and aging.
This ingredient is allowed in formulations (up to 7.5 percent), but is banned in Hawaii due to the environmental risks on coral reefs.
