Bemotrizinol, marketed by BASF as Tinosorb® S, receives regulatory approval in the United States as the first new sunscreen active ingredient approved by the FDA since 1999

  • Approval allows BASF to market Tinosorb® S, helping domestic brands and OEM/ODMs expand into overseas markets
  • Widely proven UVB and UVA protection delivers outstanding performance and photostability
  • Enables advanced, long‑lasting sunscreen formulations for evolving global consumer expectations

Shanghai, China – July 27, 2026 – Bemotrizinol (BEMT), marketed by BASF as Tinosorb® S (天来施® 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 solution for consumers globally.

Known chemically as Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine, Tinosorb® S is a highly efficient broad-range UVB and UVA filter with a long history of use in multiple markets. With FDA approval now in place, BASF adds Tinosorb® S to its innovative portfolio of proven sun care products and further expands its personal care expertise and technology leadership in the United States.

“The FDA approval of BEMT opens up new growth opportunities for customers across the Asia Pacific region,” said Chang Wang, Vice President, Business Management, Personal Care Solutions Asia Pacific. “BASF is now well positioned to support customers in developing sunscreen formulations that comply with the new regulatory framework, enabling them to accelerate innovation and gain an early-mover advantage in addressing opportunities in both the U.S. and global markets.”

Outstanding performance in broad-spectrum UV protection

Tinosorb® S was specifically designed to deliver strong and reliable broad-spectrum UV protection, covering the entire UVB and UVA range. With absorption peaks at approximately 310 nm and 340 nm, it provides broad-spectrum protection across the wavelengths most responsible for skin damage and premature aging. Widely recognized for its efficacy and photostability, Bemotrizinol maintains its performance even under intense sunlight exposure.

In addition to its primary UV protection benefits function, Tinosorb® S serves as a photostabilizer within sunscreen formulations for more photo-unstable UV filters. It helps stabilize ingredients such as avobenzone, improving the durability and effectiveness of UVA protection in complex formulations. In the U.S., where options for strong UVA protection are limited, Tinosorb® S supports sunscreen formulas in achieving a critical wavelength above 370 nm, when combined with avobenzone or Z-COTE® zinc oxides to provide broad-spectrum protection.

Thanks to its large molecular structure, Tinosorb® S exhibits low percutaneous absorption, reducing the risk of irritation. This attribute makes it particularly well suited for high‑performance sunscreens designed for sensitive skin, reinforcing its role as a trusted and proven solution in modern sun care formulations.
