Sunscreen chemical ban
90 percent of sunscreen brands sold are taking a serious toll on the environment and contribute to the bleaching and inevitable death of coral. common sunscreen ingredients octinoxate and oxybenzone (a.k.a. benzophenone-3 and BP-3), have proven to be toxic to living coral. This toxicity occurs even at a concentration equivalent to about one drop of water in an Olympic-size swimming pool. it causes destructive mutations at a genetic level, and higher concentrations of the chemical also directly correlate with increased instances of coral bleaching, which is what happens when the symbiotic algae that live in coral and color it are killed off, leaving a white skeleton. Our legislature passed a bill that bans the sale of sunscreens containing oxybenzone or octinoxate starting in 2020. And recently, the Center for Biological Diversity petitioned the U.S. Food and Drug Administration to ban both chemicals.
Coral reefs provide half the world’s oxygen and a third of its carbon absorption while also protecting our island against storms and bringing in tourism and food production. “The reef is like the supermarket of the entire ecosystem,” says Dr. Andrew Rossiter, executive director of the Waikiki Aquarium. It’s the basis for sustaining life, both below the ocean’s surface and above. And it’s remarkably easy for you to make a difference—a huge difference, in fact. The only true reef-safe ingredient is non-nano zinc oxide. 

Friends of Hanauma Bay encourage all visitors to the Hanauma Bay Nature Preserve to check the ingredients of their sunscreen products and to not use products containing oxybenzone.  When choosing a sunscreen, look for the following active ingredients: zinc oxide or titanium dioxide, which are safe mineral sunscreens. Please read up on the issues of sunscreen and the health of our corals.

Oxybenzone and Octinoxate have been banned from Hawaii. The other chemicals on this list are also harmful.  Please don't use any lotion which contains any of the following chemicals.

The HEL LIST includes:

  • Any form of microplastic sphere or beads.

Another guide to eco-friendly sunscreens


Read labels, as mainstream brands sell other sunscreens with oxybenzone and/or octinoxate. 

Spray sunscreens are not recommended by the Environmental Working Group, due to a risk of inhalation and difficulty ensuring an adequately thick and even layer on skin.

Unfortunately, our wastewater treatment facilities do NOT eliminate  chemicals in sunscreen from our wastewater or from being dumped into the ocean, so the best way to help our efforts to eliminate reef-toxic sunscreen from our marine environment is to:

1.  Avoid being in the sun during the sunniest part of the day (11-3);
2.  Wear protective clothing (hat, long sleeve shirt, rash guard) to minimize body areas that will need sunscreen;
3.  Choose to use mineral sunscreens that contain zinc oxide or titanium dioxide instead of chemical sunscreens; and
4.  Choose mineral sunscreen that is broad spectrum (protects against both UVA and UVB), and is at least SPF30 (don’t really need more than that).
