Are Green People sunscreens biodegradable?
At Green People, we are incredibly concerned for the safety of our seas and oceans. We work closely with the Marine Conservation Society and refuse to use any ingredients known to harm marine life in our sun care formulations.
Our 100% mineral sunscreens use mineral-based sun filters (non-nano Zinc Oxide and non-nano Titanium Dioxide). These are 100% biodegradable.
Some of our sun creams use a blend of mineral and chemical UV filters DHHB (Diethylamino hydroxybenzoyl hexyl benzoate) and DBT (Diethylamino butamido triazone). Considered eco-friendly examples of chemical sun cream filters, these highly photostable actives offer long-lasting protection, but do not degrade as easily as mineral filters. However, they are also known to be the best choice of chemical filters as they are the least harmful to coral reefs and are a lot less persistent in the environment than Oxybenzone and Octocrylene (more about them later!).

Why buy marine-safe sun creams?
Worryingly, the world’s supply of coral is in decline, and concerns have been raised that, in addition to climate change and overfishing, some sun cream ingredients (namely Oxybenzone) are bleaching coral and causing it to die.
In response, sales of Oxybenzone sun cream have been in several reef territories, including Hawaii and parts of the Caribbean.
Whilst safe for humans, if coral reefs encounter Oxybenzone, they can become vulnerable to disease and death, leaving fish and other marine life without a valuable source of food and shelter.
What to consider when shopping for ocean-friendly sun cream
Does it contain Oxybenzone?
Oxybenzone is considered such a threat to coral populations that its use is banned in several countries.
But you don’t have to worry about that with Green People. All our sun creams are ocean-friendly and free from Oxybenzone, Octinoxate and Octocrylene (ethylhexyl methoxycinnamate).
