At a 5K I did last month, we got some Hawaiian Tropic Biodegradable in the goodie bags.

It's not on the Hawaiian Tropic US website and I've seen some mention online that it is not yet FDA approved in the USA. The bottle appears to be labeled for Canada, so I don't know what the deal is.

I'm only plugging it because it doesn't make me break out, which is very rare (and I was worried because my previous favorite sunblock has been discontinued). It does contain methylparaben, octinoxate and oxybenzone, so it's not reef safe and not particularly human safe.

I definitely wouldn't have bought it, but I don't really mind using it since I use sunscreen very sparingly in any case, it obviously doesn't go on mucous membranes, and I don't even like swimming in the ocean.
