[Sun Care][PSA] List of Biodegradable Reef-Safe Sunscreens

I've been searching for potential biodegradable reef-safe mineral sunscreens for a diving vacation (though now realising I should probably always wear reef-safe sunscreen no matter where I am) and thought I'd share in case it's helpful to those wanting to choose a sunscreen that's not harmful to marine life.

This is still a work in progress but I've seen more and more posts on the sub about this subject so I thought I'd go ahead and share. If I've missed any brands out or included any products I shouldn't have please let me know and I'd love to hear reviews if you've tried any. (Also this is my first post, I hope the formatting is okay, please be kind, thanks)

Note: the criteria for inclusion here are no nano zinc oxide or nano titanium dioxide, and no oxybenzone, octinoxate, octocrylene, PABA, enzacamene, octisalate, homosalate or avobenzone. And I've tried to mention if a sunscreen contains silicones as these may potentially be a problem for marine life. As with everything, we each have to weigh up a variety of concerns, and I'm not trying to suggest that there's no point in using sunscreens containing silicones, just as I'm not trying to tell anyone that they should feel guilty if they can't use reef-safe sunscreens for any reason.

Here are the brands I've looked at so far:
