For Natural Sunblock Breakthrough, Scientists Look to Fish -
Substance filters UV rays more effectively than traditional sunscreens, researchers say

The research team, including scientists from Sweden, Spain and Australia, used organic compounds called mycosporines that fish species living on Australia’s Great Barrier Reef produce to help protect their eyes and tissues from sun damage. Previous studies identified the UV-absorbing properties of mycosporines. But the latest research managed to set the compounds in combination with chitosan, a polymer derived from crustacean shells and insects.

So far, the material has been used to create a clear film whose properties have been tested in the lab. It can also be formed into emulsions and gels that are nontoxic and resistant to moderate amounts of heat and don’t easily wash off in water. The material is odorless, despite its origin in mucus from reef fishes, algae and fish eye lenses.
