When looking at sunscreen formulation, the starting point has to be the list of permitted UV absorbers for the target region. The good news is that an additional material, tris-biphenyl triazine, was admitted to the European list in August 2014 and it is available as Tinosorb A2B, a 50% glycolic dispersion, from BASF. It may be used at up to 10% active by weight in the final composition and it protects the skin against UV wavelengths ranging from 290nm-340nm. It is described as a water-dispersible and efficient UVB/UVA II filter that offers more flexibility for the formulator, making it easy to achieve the required UVA criteria using only Tinosorb A2B and metallic oxides.
