Oxybenzone bad for corral reefs?
High level of exposure to a sunscreen additive shown to be a problem. (Article in legit science resource)
https://t.co/O788I5QmtSBut the rest of the story…
As with all of these experiments thus far, researchers looked at unrealistically high levels of exposure. https://t.co/tOPpA4Iv1c -

There are complementary sunscreen ingredients like Meroxyl.

@Syl - I haven’t seen any research to demonstrate that Meroxyl doesn’t have the same problems as other sunscreen actives. Lack of data is not a point in favor of any ingredient.

I looked through SDS of different sunscreen ingredients - chemical, zinc oxide (nano, non-nano), and in all SDS I checked, I found information: very toxic to aquatic life with long lasting effects. Isn’t that a problem for most (if not all) ingredients of this type?
So far, I think non-nano coated zinc oxide is the best choice given the gaps in the data on chemical sunscreen actives. -
SDS refers risk associated with the raw material. to address risk in product application, one would need to consider dose - as Perry noted in the initial post..

@grapefruit22 - wouldn’t exposure of aquatic life to 100% non-nano, coated zinc oxide result in the death of said aquatic life?

@PhilGeis
Sure, my point is that if oxybenzone is risky only as a raw material, and other raw sunscreen ingredients could also be risky, why is only Oxybenzone mentioned as a problem for reef, and other sunscreen ingredients are “reef-safe”?@Perry
All SPF ingredients I found had warning “Harmful to aquatic life with long-lasting effects”
For me, a non-nano zinc oxide is better, because at least it’s not absorbed through the skin.
