Solubilizing Emollients Bring Sun Care to the Next Level

The recent approval of Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine (Bemotrizinol), marketed by BASF as Tinosorb® S, by the U.S. Food and Drug Administration (FDA) as a sunscreen active ingredient marks an exciting new chapter for sunscreen innovation.

Long recognized globally as one of the most efficient broad-spectrum UVA and UVB filters available, Tinosorb® S delivers outstanding photostability and helps formulators create high-performance sun care products with long-lasting UV protection. Yet maximizing the benefits of this advanced UV filter requires more than selecting the ingredient itself, it also requires the right formulation expertise and appropriate solubilization strategy.

From Solubility to Sensory Delight: The BASF Advantage in Sun Care Innovation

Because Tinosorb® S is an oil-soluble crystalline UV filter, solubility plays a critical role in formulation success. Efficient solubilization helps create a clear and homogeneous oil phase, reducing the risk of recrystallization and supporting long-term formulation stability. For formulators, this means greater flexibility when developing high-SPF products. For consumers, these technical advantages translate into elegant textures, more uniform product applications, and a more pleasant and consistent skin feel. A well-solubilized filter system can also help support high UV performance without creating the heavy, greasy sensory profile often associated with high-SPF sunscreens.

Cetiol® B (Dibutyl Adipate)

One of BASF's most effective solvents for dissolving challenging crystalline UV filters such as Tinosorb® S, helping formulators achieve high UV filter loading while maintaining clarity and stability.

Cetiol® ABV (C12-15 Alkyl Benzoate)

Adds excellent solubilization power and superior spreading characteristics, contributing to smoother application and more uniform product coverage.

Cetiol® CC (Dicaprylyl Carbonate)

Fast-spreading emollient and an excellent alternative to silicones. It delivers a pleasantly dry and velvety sensation that helps offset the richness often associated with high-protection sunscreen systems.

The balm combines Tinosorb® S with Cetiol® ABV, which helps efficiently solubilize the UV filter system and support formulation uniformity. This optimized combination contributes to a smooth, homogenous balm texture and a seamless glide across the skin. Consumers benefit from easier product spreadability, improved comfort during application and a more elegant finish.

Beyond solubilization, the concept showcases the versatility of BASF's emollient portfolio. Cetiol® CC provides a fast-spreading profile, while Cetiol® SoftFeel contributes a richer, cushioned skin feel. Together, they create a balanced sensory profile that feels soft, nourishing and comfortable without the heaviness that consumers often associate with sunscreen balms. The result is a modern SPF product that delivers robust UV protection while leaving skin feeling silky, conditioned and cared for.

Finally, the concept also incorporates Sqisandryl™ active to support energized and firm-looking skin, reinforcing the growing convergence between skin care and sun care.
