Sun Balm’s active is Zinc Oxide. Zinc Oxide is generally recognised as the most Reef Safe of all sunscreen active ingredients.
Zinc Oxide is relatively insoluble in seawater. It is a mineral that is likely to settle on sea floor in sedimentary layer. In contrast chemicals like Oxybenzone are highly mobile and can spread far and wide by ocean currents.
Sun Balm has a high water resistance, meaning that not much washes off into the water. The less that washes off, the better for the environment.
The rest of our inactive ingredients are plant oils, cocoa butter and beeswax, most certified organic. These are all biodegradable and safe for the environment.
