In this post, we explore the sea-safe ingredients that make our sunscreens so effective at keeping your skin safe in the sun.

We also reveal the important reason why we refuse to use Oxybenzone and Octinoxate in our marine-friendly, natural sun creams.

Our ocean-friendly sun cream policy

One question we often get asked is, ‘Is Green People sun cream reef safe?’ and, as a proud partner of the Marine Conservation Society, we’re very strict about what goes into our marine-friendly sun creams.

To make our natural and organic sunscreens as safe for the sea as they are for your skin, we refuse to use the following sunscreen ingredients, which are known to be harmful to coral reefs. 

  • Ethylhexyl methoxycinnamate (also known as Octinoxate)
  • Benzophenone-3 (also known as Oxybenzone)

Did you know:

Oxybenzone poses such a great risk to reefs that several coral reef areas have banned its use completely.  Hawaii, Aruba and Palua are just some of the territories that have banned the use of Oxybenzone suncream as part of their fight to preserve their coral reef populations.

Why should Oxybenzone be avoided?

The UK isn’t exactly known for its coral communities, so you may wonder why we, as a British sun cream brand, are so committed to making Oxybenzone-free sunscreens.

The truth is that our seas are at risk, not only from coral-harming sunscreen filters but also from climate change, agricultural pollution, and overfishing,

Coral reefs aren’t just scenic snorkelling spaces. They provide a vast amount of Earth’s oxygen and are a sanctuary for many species of marine life. Without the reef, some species of fish could go extinct, leading to the destruction of some marine ecosystems.

Shocking statistic: 14,000 tonnes of sunscreen are thought to wash into the oceans each year[i]

Having worked with the UK’scharity, MCS, for over a decade, we are greatly concerned that some sun cream filters could harm fish and coral reefs.

Wondering how our sunscreens work? Read on.

Our mineral sun filters


Zinc Oxide is a natural mineral sun cream filter that’s a great choice for oily and spot-prone skin. Found in our Scent Free Mineral Sun Cream, this, uncoated sun filter is non-nano and works mainly by physically reflecting UV rays so that  harmful radiation cannot reach the skin surface.

Zinc Oxide is not known to display aquatic toxicity, and there are lots of benefits to using it in sun care. Firstly, it starts to work as soon as it is applied to the skin, so it is ideal for when you want instant protection. It’s also largely unaffected by UV rays, meaning it will continue to work if it remains on the skin. You should always re-apply regularly and liberally though.

Zinc Oxide powers the below 100% mineral sunscreens:


Non-nano Titanium Dioxide is another mineral sun filter we use to make our marine-friendly SPFs so effective. Found in our Edelweiss Sun Cream SPF15 with Tan Accelerator, this mineral sun filter acts as a reflective barrier predominantly to UVB radiation and has no known hormone-mimicking effects.

Our chemical sun filters


Some Green People sun creams also contain a filter called Diethylamino Hydroxybenzoyl Hexyl Benzoate. This gives protection specifically against UVA radiation. We often use this in conjunction with Diethylamino Butamido Triazone, a sun filter which protects against UVA and UVB but is especially effective in the UVB spectrum.

Diethylamino Hydroxybenzoyl vs Oxybenzone

We often get asked if Diethylamino Hydroxybenzoyl Hexyl Benzoate is the same as Oxybenzone and if it is reef safe.

You’ll be pleased to hear that Diethylamino Hydroxybenzoyl Hexyl Benzoate is distinctly different from Oxybenzone. Not only does it have an excellent safety profile, but it is very well tolerated even by ultra-sensitive skin, biodegrades readily and has no adverse environmental effects.


A plant-based UV-protection booster, antioxidant Edelweiss has evolved to withstand very strong UV light levels at high altitudes. It offers powerful protection against free radical damage and contains lignans and leontopodic acid, which calm the skin and help to protect against sensitivity.
