What is this product?

Chemical UV filters oxybenzone (benzophenone-3) and octinoxate (ethylhexyl methoxycinnamate) documented to cause coral bleaching, DNA damage, and reproductive toxicity in coral at concentrations as low as 62 parts per trillion. Hawaii (2021), Palau (2020), Key West (2021), US Virgin Islands (2020), Aruba, and Bonaire banned these filters. 'Reef-safe' is not a regulated term — no standard definition. Mineral sunscreens (zinc oxide, titanium dioxide) are generally considered reef-safer but nano-form effects debated.
