Hawaii’s coral reef ecosystem is home to over 7,000 aquatic species and plants. It also prevents harmful shoreline erosion. To protect these sensitive reefs, the state recently banned the use of sunscreens that may damage them. If you have an upcoming snorkeling trip, purchase a product that will minimize your impact on the ecosystem. 

Hawaii’s Sunscreen Ban

In 2018, Hawaii passed a bill banning the sale of sunscreen products that pose a risk to coral reefs. Going into effect on January 1, 2021, stores will be prohibited from selling over-the-counter sunscreen containing oxybenzone and octinoxate. These, along with other chemicals, are thought to heavily contribute to coral reef damage.

Ingredients to Avoid

Until the ban goes into effect, avoid purchasing sunscreen products containing oxybenzone and octinoxate. These two banned ingredients are responsible for coral bleaching. When this occurs, coral become stressed, and algae, their food source, leave. The coral begin to starve, turn white, and eventually die.

Avoid parabens as well. These preservatives are found in many sunscreens. Two forms, butylparaben and methylparaben, have been shown to contribute to coral bleaching.

Alternatives

Mineral-based sunscreens are much safer than chemical products. These include non-nanotized zinc oxide or titanium dioxide. “Non-nanotized” refers to the diameter of each particle of the ingredients. The smaller they are, the less invasive. Look for these ingredients specifically; don’t just take the word of a “Reef-Safe” label on the packaging.

Also, opt for paraben-free, rub-in options. Spray sunscreens are more likely to catch in the wind and settle on sand or open water.

A collective effort to use reef-friendly sunscreens may drastically cut down on bleaching and other harmful side effects, so you can be confident you leave a minimal footprint while snorkeling in Hawaii.
