What’s coral’s beef with sunscreen?

In May 2018, Hawaii announced it had passed a bill to ban certain sunscreens that are harmful to coral reefs. The ban will come into place in January 2021.

The bill was in response to a study that suggested two chemical sun filters, often found in sun protection products, had a harmful impact on coral reefs.

Coral damage

The study in question was published in the journal, ‘Archives of Environmental Contamination and Toxicology’.

It found that specific chemical sun filters have a range of effects on coral, including mortality in developing coral, bleaching of coral and genetic damage to coral and other organisms.

The study also found that both chemicals induce feminisation in adult male fish and increase reproductive diseases in creatures from sea urchins to parrotfish and mammal species similar to the Hawaiian monk seal.

The chemicals can also induce neurological behavioural changes in fish and have possible impact on the many endangered species found in Hawaii’s waters, including sea turtles.

The opposing view

On the other hand, the bill has its critics.

There are suggestions the decision is based on a limited body of scientific research. With the ban affecting an estimated 70% of sun protection products on the market, the move will make it more difficult for people to protect themselves.

To that point, the American Chemistry Council opposed the bill on the basis that sun exposure to humans is also a danger.

The alleged culprits

The two UV filters thought to cause coral damage are:

  • Oxybenzone (described as Benzophenone-3 on European labels) and
  • Octinoxate (described as Ethylhexyl Methoxycinnamate).

For the avoidance of doubt, neither of these ingredients are used in any LifeJacket products

Suncare is (quite rightly) heavily regulated

Within Europe there is a defined list of the UV filters that are allowed to be used in cosmetic products.

For those of you who care, this is covered under Annex VI of the EC regulation 1223/2009.

The filters on the list have extensive data available concerning their safety and use. The list also sets out permitted conditions of use and the maximum concentration of the filter in a cosmetic product.
