The patent relates to novel compounds able to absorb UV radiation and comprize antimicrobial properties as well. The compounds herein described are novel and undisclosed scytonemin analogs, able to absorb up to 90% of UV-A radiation and cover a broader UV to blue light absorption. The compounds described can be easily incorporated into formulations to be used in cosmetic products, sunscreens or lenses for sunglasses.
Ultraviolet (UV) radiation is a harmful and mutagenic component, causing premature skin aging, eye damage, and skin cancer. In addition, blue-violet light may act as silent and long-term aging energy, causing inflammation, wrinkles, hyperpigmentation and others. There is a clear tendency for the development of broad range sun care products that can protect from UV-A, UV-B and blue-light.
The patent is related to scytoneminanalogs, a novel class of compounds, obtained from natural sources, namely cyanobacteria. These compounds can absorb up to 90% of UV-A radiation and can cover a broader UV to blue light absorption range. The compounds present faint colouration, and some are even colourless, thus being easily incorporated in formulations for cosmetic products, sunscreens or lenses for sunglasses.
Furthermore, some of these molecules present interesting antimicrobial properties, acting as multifunctional ingredients.
