Abstract
A highly photostable, broad spectrum (UVA/UVB) sunscreen composition having an SPF of greater than 50 that retains about 90% of its UV absorbance over the range of 290 nm to 400 nm after being irradiated with 15 MEDs of energy from a simulated solar radiation source calibrated in accordance with the COLIPA standard. The highly photostable sunscreen composition is comprised of at least one dibenzoylmethane derivative, preferably avobenzone, and at least four compounds that quench singlet-excited energy and/or triplet excited energy, respectively 'singlet quenchers' and 'triplet quenchers'.
