200 Scientists Want Tougher Limits on Chemicals in Personal Care Products

In June of 2017, a group of 200 scientists and medical professionals called on the international community to ratchet up restrictions on the production and use of triclosan and triclocarban – 2 antimicrobial chemicals found in shampoos and cosmetics. They cite “extensive peer-reviewed research” which suggests the ingredients are potentially harmful. [1]


In late 2016, the FDA banned 19 chemicals in hand and body soap over concerns about their effect on human health and the environment. Despite the ban, dangerous chemicals are still commonly used in other personal care products.


A senior scientist with the Environmental Working Group (EWG), David Andrews said:




“Other ongoing uses are not addressed by the recent FDA action, and more needs to be done.” [2]


The group of scientists and medical professionals said in a statement published in the journal Environmental Health Perspectives that the chemicals, which have been used for decades, should be reserved for use only in situations where there is an “evidence-based health benefit.” [1]


They added:


“Greater transparency is needed in product formulations, and before an antimicrobial is incorporated into a product, the long-term health and ecological impacts should be evaluated.”


There is evidence to suggest that triclosan and triclocarban, both endocrine-disruptors, persist in the environment, where they may harm aquatic life and other organisms. The group’s primary concern is that the chemicals’ pervasiveness may be contributing to antibiotic and antimicrobial resistance and the rise of deadly superbugs.


As endocrine-disruptors, triclosan and triclocarban can affect the hormone cycles and development of organisms. The chemicals have also been linked to increased susceptibility to allergens.

The FDA regulates certain products containing triclosan, including cosmetics, toothpastes, shampoos, and soaps. But there are other products not regulated by the agency that also contain the gender-bending chemical, including clothing, credit cards, cutting boards, blankets, mattresses, bathtubs, furniture, and toys. Furthermore, there is no limit on the use of triclosan and triclocarban in household or building products. [2]


Andrews said:


“For decades, the American public has been led to believe that antimicrobial products would make us healthier and safer.” [1]


Nothing could be further from the truth.


Label These Chemicals


The group wants the chemicals to be listed on labels of all consumer products that contain them. Additionally, it wants the FDA and the EPA to restrict unnecessary use. It notes in its statement that some companies, including Procter & Gamble and Johnson & Johnson, have already begun phasing out triclosan and triclocarban. [2]


The American Cleaning Institute and the Personal Care Products Council maintain that scientific evidence is on their side, and shows their products are safe and effective, and do not contribute to antibiotic and antimicrobial resistance. Both groups warn that banning or restricting the chemicals may lead to an increase in infections and disease. [1]


Studies show, however, that triclosan-containing soaps work no better than regular hand soap at killing germs.

How to Pick a Sunscreen That’s Safe for Coral Reefs and Aquatic Life

Hopefully, before you head to the beach, you’ve already looked for some safe sunscreens for your body. But if you’re not reading labels, and if you don’t understand what the ingredients on those labels are, studies show the product you’re lathering on your skin could actually pose a grave threat to the ocean environment. These sunscreens are especially not safe for coral reefs.


The world’s most popular reefs are at risk because of a common chemical found in all types of sunscreen: Oxybenzone. [1]


Oxybenzon – Why Sunscreen is NOT Safe for Coral Reefs, Aquatic Life


According to a study published in 2015, oxybenzone poisons coral by contributing to bleaching, has a similar effect on DNA to gasoline, and causes young corals to become fatally deformed because the chemical disrupts reproduction and growth.




Craig Downs, one of the study’s authors, explained:


“It causes weird deformities in soft tissue and also causes the coral larvae to encase itself in its own skeleton, in its own coffin.”


A dose of oxybenzone the size of a drop in 6.5 Olympic swimming pools is enough to damage coral reefs.


Downs said:


“Oxybenzone can cause an adverse effect in coral at 62 parts per trillion, that is equivalent to one drop of water in six and a half Olympic size swimming pools, so you don’t need a lot to cause a lot of damage.” [2]


In fact, scientists have discovered that many beaches popular with tourists have dead and sterile reefs, compared to beaches with little human traffic, which are healthy. [1]


It is believed that up to 14,000 tons of sunscreen is deposited on coral reefs each year. [2]


Hawaii is contemplating banning oxybenzone-containing sunscreens on the islands for this reason. Sunscreen isn’t safe for coral reefs!


Other sea life is imperiled by oxybenzone, as well. Downs’ team found the chemical has toxic effects on fish larvae and embryos. [1]


How to Ensure You’re Buying Sunscreen Safe for Coral Reefs


Some sunscreen manufacturers have started producing and marketing sunscreens as “reef friendly,” but there’s no way to know for sure what you’re getting. Scientists warn that, like the “natural” and “healthy” labels on food, there is little to no regulation over such claims.

So here are a few tips for picking a sunscreen that is, indeed, reef-friendly.


Read Labels





Look for sunscreens containing the “Protect Land + Sea” Certification Seal. This means the product has been laboratory-tested using analytical-forensic techniques to verify that it is free of the following chemicals:


  • 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)

  • Methyl Paraben

  • Ethyl Paraben

  • Propyl Paraben

  • Butyl Paraben

  • Benzyl Paraben

  • Triclosan [3]

While sunscreens containing ONLY zinc oxide and titanium dioxide are considered reef-friendly, when these ingredients are uncoated and nano-size (less than 35 nanometers in diameter), they can enter the cells of invertebrates and cause oxidative stress in sunlight. Downs explains that “This blows up the cells so they die.” [4] [5]


Buy Sunscreens with the Simplest Formulas


According to Downs, even oils added to sunscreens, such as eucalyptus and lavender, can harm invertebrates. Industrial insecticides can contaminate beeswax, that, when emulsified in beauty products, can release these chemicals on your skin and in the water. This is why it’s so important to buy organic sunscreen.


Don’t Buy Aerosols



Aerosol sunscreens are worse for reefs than other types because it travels and leaves residue in the sand. Waves wash the sand and the residual ocean spray into the oceans. [2]


When researchers sprayed a small piece of coral from Trunk Bay in the U.S. Virgin Islands with one of the top aerosol brands, the coral lost all its algae, and turned white and bleached within 96 hours.


John Burns, PhD and coral biologist, who has worked on coral health and disease for nearly a decade, said:


“They actually have a basic immune system that is a lot like humans, they react when they are being stressed out. When they’re white, their stressed, it’s a lot like us, when we’re sick, we’re pale and we’re not as healthy, and that’s what’s happening to the coral.”


Now that we know that most sunscreens aren’t safe for coral reefs or ourselves, let’s make it a goal to explore other, safer options for protection this summer.
