Bemotrizinol (BEMT), marketed by BASF as “Tinosorb” S, has received approval from the U.S. Food and Drug Administration (FDA) as a sunscreen active ingredient. Developed by Ciba Specialty Chemicals and later integrated into BASF through acquisition, BEMT is now available to the U.S. sunscreen market as one of the most effective UV filters. It is also the first new UV filter to be approved by the FDA in 27 years. This marks a significant advancement in sun protection for American consumers.
