BASF has announced the availability of its sunscreen ingredient Tinosorb S, also known as Bemotrizinol, in the United States following recent approval by the U.S. Food and Drug Administration (FDA). The move is seen as an important development for the American sunscreen industry, where access to some newer UV protection ingredients has been limited.
Tinosorb S is a modern sunscreen ingredient designed to provide broad protection against ultraviolet (UV) radiation. It helps protect the skin from both UVA and UVB rays, which are two major types of UV radiation that can damage the skin.
UVA rays can contribute to long-term skin damage and premature aging, while UVB rays are strongly linked to sunburn. A sunscreen that provides protection against both types of radiation is known as a broad-spectrum sunscreen.
One of the main benefits of Tinosorb S is its high photostability. Photostability means that an ingredient can maintain its performance when exposed to sunlight. This is important because some sunscreen ingredients can become less effective after prolonged exposure to UV light.
Tinosorb S is designed to remain stable under sunlight, which can help sunscreen products maintain consistent protection. Its stability may also help improve the performance of other UV filters used in the same sunscreen formulation.
The ingredient is being introduced in the U.S. through a licensing agreement with DSM Nutritional Products LLC. Under the agreement, BASF has co-exclusive rights to market and sell Tinosorb S in the United States.
The rights apply to sunscreen products manufactured in the U.S. as well as products that are made in other countries and imported into the American market.
The availability of the ingredient could give sunscreen manufacturers more options when developing new products. Companies may be able to use Tinosorb S in different formulations to improve broad-spectrum protection and product stability.
The development is particularly significant because the U.S. sunscreen market has historically had access to fewer modern UV filters compared with some other regions. The introduction of a newer ingredient could encourage manufacturers to explore more advanced sunscreen formulas.
For consumers, the availability of new sunscreen ingredients could eventually lead to more choices in sun protection products. However, the benefits of any final sunscreen product will depend on its complete formulation and how it is used.
Sun protection remains important for reducing the harmful effects of excessive UV exposure. Dermatologists generally recommend using broad-spectrum sunscreen and taking other protective measures, such as wearing protective clothing and avoiding excessive sun exposure.
BASF’s introduction of Tinosorb S therefore represents a notable change in the U.S. sun care market. Its broad-spectrum protection and strong stability under sunlight make it an important ingredient for manufacturers looking to develop effective modern sunscreen products.
As more companies gain access to advanced UV filters, the U.S. sunscreen industry could see greater innovation and a wider range of products designed to provide reliable protection from the sun.
