• Unprotected exposure to solar UV is the main recognized cause of the spreading of skin cancer that has occurred in the last decades. Organic and inorganic UV filters are the main defense against UV exposure and have become ubiquitous in personal-care products, packaging, plastics, dyes, and many other sectors. UV filters still have some stability and efficacy issues making it important to find stable and broad-spectrum UV absorbers, safer for human health and the environment. In this work UV filters octinoxate and avobenzone were encapsulated into zeolites with different chemistry and topology leading to the production of hybrid zeolites/organic filter sunscreens. The obtained materials were deeply characterized and their filtering capacity evaluated. The encapsulation of UV filters in cationic zeolites resulted in an enhanced UV filtering capacity, whereas that in acid zeolites seem less effective in absorbing UV radiation, with emerging visible coloring. The enhancement of UV filtering power is of paramount importance for the future development and exploitation of ZEOfilters, possibly being the key to reduce the quantity of actives, stabilizers, and co-formulants employed, with benefits for humankind and the environment.
