Popular Science tells the story of proposed legislation which would provide that (quoted from the bill)
No person shall use or apply sunscreen, sunblock, or cosmetic containing any oxybenzone while on a beach or in the ocean.
The article seems to imply a broader ban, saying
[...] Hawaii's ban, if successful, would be unusual for its scale—it would be state wide, across all of the islands, affecting even those who may never set foot in the ocean.
The bill, it says, is motivated by studies indicating that oxybenzone (also known as benzophenone-3), can harm coral.
