Plant pollen finds use in coral-friendly, skin-cooling sunscreen | An experimental new sunscreen forgoes the minerals altogether, replacing them with "just-as-effective" plant pollen.
Minerals such as titanium dioxide and zinc oxide are very effective sunscreen ingredients, but they can harm coral reefs if used in their non-nanoparticle form. An experimental new sunscreen forgoes the minerals altogether, replacing them with "just-as-effective" plant pollen.
When applied to animal skin in lab tests, that gel was found to block harmful ultraviolet rays as effectively as a conventional mineral- or chemical-based sunscreen with an SPF rating of about 30. As an added benefit, because sporopollenin absorbs less energy than regular sunscreen in the visible to near-infrared spectrum, the microgel was found to keep the skin a total of 5 ºC (9 ºF) cooler for 20 minutes after application.
