  • Publication number: 20210304851
    Abstract: A computer-based method for determining a sunscreen composition comprising a plurality of UV filter substances, comprises the steps of selecting at least one constraint for at least one characteristic of the composition to be determined (step 30), the at least one constraint comprising a sunscreen performance target; selecting an optimization objective from a plurality of optimization objectives (step 50); and automatically determining the sunscreen composition as a composition of filter substances from a set of filter substances (step 100), the composition meeting the at least one constraint and being optimized with respect to the selected optimization objective. The automatic determination comprises the steps of generating a plurality of candidate compositions, determining a sunscreen performance of the candidate compositions using a performance simulation tool and comparing the determined sunscreen performance of the candidate compositions with the sunscreen performance target.
