Reef Safe Sunscreens / Coral Friendly Sunscreens

Sunscreen washes off your body when you swim and shower and enters the marine environment.

Common chemical sunscreen ingredients, such as oxybenzone and octinoxate, can kill coral and damage coral reefs.

Badger's reef safe sunscreens never use any of these harmful ingredients and we were one of the first to receive the Protect Land & Sea Certification.

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 HEL LIST is a list of personal care and sunscreen ingredients that are known environmental pollutants and threaten ecosystem health. This list includes:

In 2020 the Haereticus Environmental Laboratory tested two Badger sunscreens and they were free of any of these ingredients earning us one of the very first Protect Land & Sea Certifications! Check out our Protect Land & Sea Certified sunscreen in a tin!

What can you do to help protect coral reefs?

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. Not only do we not use any of the harmful ingredients on the HEL LIST (see above) but we had two of our sunscreens tested by and they were found to be free of any of these ingredients earning us one of the very first Protect Land & Sea Certifications!

• The only active ingredient in each of our sunscreens is the mineral zinc oxide, and we do not use nano sized zinc. This has been used in skin care for thousands of years and is the same ingredient used in diaper creams, calamine lotion, and toothpastes. It is a powdered mineral that does not dissolve in seawater and because our zinc oxide is has a large particle size it rapidly settles to the seafloor and becomes part of the sediment. Read more about zinc oxide.


• The inactive ingredients of our water resistant sunscreens (making up 77-88%) are USDA organic plant oils, beeswax, vitamin E, and other ingredients that are sustainably sourced from plants, minerals, or are a product of fermentation, and safe for any environment or ecosystem.


• Reef Safe vs. Reef Friendly: You may have noticed both of these terms being used in sunscreen articles and by sunscreen companies, even here at Badger. While they essentially mean the same thing we see a difference. To us, ‘reef safe’ is a product safety claim that should be backed up by scientific proof that the product was tested on living coral and caused it no harm. However, there are no standardized test to prove that a sunscreen is 100% safe for coral. The best we can do is to guarantee that our sunscreens don’t contain any of the ingredients shown to harm coral, and for this we use the term ‘reef friendly’. We sometimes use both terms interchangeably on our website and in our writings because people recognize the term ‘reef safe sunscreen’ over ‘reef friendly sunscreen’ but we have chosen to only use ‘reef friendly’ on our sunscreen packaging.
