Staying safe and carefree in the sun

Formulating high-SPF sunscreens represents a challenge for manufacturers: The large oil phase usually necessitated by UV filters that are oils or only soluble in oil tends to weigh down sunscreens, resulting in products that are inconvenient to apply and that leave an unpleasant feeling on the skin.

BASF recently developed a new technology that incorporates the oil-soluble, high-performance, broad-spectrum UV filter Tinosorb® S in the water phase. The UV filter formulation Tinosorb® S Lite Aqua enables manufacturers of sun care products to develop sunscreens that combine maximum protection with a light sensation on the skin.

To protect their skin against the damaging effects of the sun, consumers want light, pleasant-feeling sunscreens: Products that are easy to apply and are quickly absorbed without leaving their skin feeling greasy, while also providing a high sun protection factor (SPF). But since most UV filters are either oils or oil-soluble, formulating products with a reduced oil phase can be challenging for manufacturers. 

BASF experts recently developed a new technology that incorporate the oil-soluble, high-performance and broad-spectrum UV filter Tinosorb® S (INCI: BisEthylhexyloxyphenol Methoxyphenyl Triazine, abbreviation: BEMT) in the water phase by solubilising the filter active in a polymer matrix. Tinosorb S Lite Aqua (INCI: Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine (BEMT) (and) Acrylates/C12-22 Alkyl Methacrylate Copolymer) enables manufacturers to include the same active in both the oil and water phase – facilitating light formulations with a reduced oil phase. In vivoand in vitrotests have proven the performance and water resistance of formulations with the solubilised BEMT.
