A brief summary of the science:

Between 6000 and 14,000 tons of sunscreen washes off swimmers, scuba divers, and snorkelers into coral reef environments each year. Even more sunscreen pollution can reach coastal areas via waste water discharges. Up to 10% of the world's coral reefs may be threatened by certain chemicals found in most sunscreens.

Four common sunscreen ingredients were shown to kill or bleach coral at extremely low concentrations (as low as one drop in 6.5 Olympic sized swimming pools).

• Oxybenzone (Benzophenone-3, BP-3) - Sunscreen ingredient that disrupts coral reproduction, causes coral bleaching, and damages coral DNA. Oxybenzone is found in over 3500 sunscreen products worldwide.
• Butylparaben - Preservative ingredient shown to cause coral bleaching.
• Octinoxate (Ethylhexyl methoxycinnamate) - Sunscreen ingredient shown to cause coral bleaching.
• 4-methylbenzylidene camphor (4MBC) - Sunscreen ingredient shown to cause coral bleaching. Allowed in Europe and Canada, not in USA or Japan.

The Haereticus Environmental Laboratory researches the effects of sunscreens and other personal care ingredients on coral reefs and on other ecosystems and wildlife. Their list of ingredients that they consider to be environmental pollutants includes:

• Any form of microplastic sphere or beads.
• Any nanoparticles like zinc oxide or titanium dioxide.
• Oxybenzone
• Octinoxate
• 4-methylbenzylidene camphor
• Octocrylene
• Para-aminobenzoic acid (PABA)
• Methylparaben
• Ethylparaben
• Propylparaben
• Butylparaben
• Benzylparaben
• Triclosan

What can you do to help?

Global warming, pollution, and other human activities pose additional and significant threats to the survival of coral reefs. However, the results of these sunscreen studies should be taken seriously and if you plan to swim, scuba dive, or snorkel near coral reefs you should use a coral reef friendly or reef safe sunscreen. How can you tell if a sunscreen is safe for coral reefs?

• Badger sunscreens do not contain any of the ingredients shown to harm coral and most are water resistant.


• The only active ingredient in each of our sunscreens is the mineral zinc oxide. This has been used in skin care for thousands of years and is the same ingredient used in diaper creams, calamine lotion, and toothpastes. Unlike oxybenzone and other sunscreen ingredients there is no evidence that zinc oxide harms coral. It is a powdered mineral that does not dissolve in seawater and instead becomes part of the seafloor sediment. Read more about zinc oxide.


• The inactive ingredients of our water resistant sunscreens (making up 77-88%) are USDA Organic plant oils, beeswax, and vitamin E. These are all biodegradable and safe for any environment or ecosystem.
