    @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.
