BASF Launches Tinosorb S UV Filter in the US

The launch of Tinosorb S by BASF in the United States marks a significant development in the country's sunscreen market. According to BASF, the ingredient enables manufacturers to develop high-performance formulations with long-lasting protection and enhanced skin defense. Tinosorb S, also known as Bemotrizinol, is a broad-spectrum UV filter that delivers protection across both the UVA and UVB ranges.

## Introduction to Tinosorb S Tinosorb S is recognized globally for its exceptional photostability, helping maintain sunscreen performance during UV exposure and improving the photostability of other UV filters used in formulations. This characteristic has made Bemotrizinol a key component in many advanced sunscreen systems outside the United States, particularly in Europe and Asia.

## BASF's Sun Care Offering BASF's UV filter portfolio includes the Tinosorb, Uvinul, and Z-COTE product families, complemented by a wide range of formulation ingredients such as emollients, emulsifiers, rheology modifiers, film formers, and cosmetic active ingredients. By combining UV filters with formulation support, BASF aims to provide an integrated development platform for sunscreen manufacturers. The company's approach can help customers create next-generation sun care products that combine high-performance UV protection, exceptional sensory attributes, and sustainability-focused innovation.

## Implications for the US Sunscreen Market The FDA approval of Tinosorb S is expected to broaden formulation possibilities for US sunscreen brands seeking to improve efficacy, stability, and consumer experience while aligning more closely with international sun care standards. Industry observers have long viewed Bemotrizinol as one of the most significant modern UV filters absent from the US market. Its approval could stimulate reformulation activity across premium and mass-market sunscreen categories, including facial sunscreens, body protection products, and multifunctional skincare with SPF claims. The launch may also create new opportunities in formulation optimization and product differentiation, particularly as consumers increasingly demand sunscreens that deliver broad-spectrum protection, photostability, reliable performance, and cosmetic elegance.

BASF intends to work closely with sunscreen manufacturers, brand owners, and formulators across the United States to accelerate the commercialization of products incorporating Tinosorb S. The company's strategy in sun care ingredients is reinforced by the launch, which is expected to have a significant impact on the US sunscreen market. With the introduction of Tinosorb S, BASF is well-positioned to support the development of high-performance sun care products that meet the evolving needs of consumers.
