Conventional sunscreens can harm marine life like corals, with an estimated 6,000 to 14,000 metric tons entering the ocean annually. Hawaii and Aruba have banned certain harmful sunscreens. Material scientists at Nanyang Technological University in Singapore have developed a new, coral-safe sunscreen. This innovative sunscreen utilizes camellia flower pollen instead of chemical or mineral filters to block UV rays. The pollen's natural resilience to UV radiation inspired the researchers to create a bio-inspired, sustainable sunscreen. Its unique structure filters harmful UV rays while remaining visually transparent and biodegradable. The pollen is processed into a microgel formula that applies as an ultra-thin layer and provides a cooling effect by allowing visible and near-infrared light to pass through. Lab tests show the camellia pollen sunscreen effectively blocked UV radiation, comparable to mineral sunscreens with an SPF of about 30. Crucially, unlike commercial sunscreens that caused coral bleaching and death, the pollen-based sunscreen showed no harm to corals even after 60 days. This pollen sunscreen also avoids nanoparticles and is designed to be non-allergenic, offering potential human safety benefits.
