AI to predict Sunscreen Performance?

The first Sunscreen Simulator was developed and made available on the Internet by Ciba Specialty Chemicals in 2002. In the meantime, it has been improved by BASF 2011, and since 2017 we also have the DSM Sunscreen Optimizer on the Internet. Does this mean that we have an artificial intelligence (AI) solution to predict sunscreen performance? Although there is now quite a hype about AI, I would not call it that. Sunscreen simulators are conventional bottom up calculations based on physics and a model of the sunscreen film on the skin, calibrated with a few dozen data points of well-known SPF value. Although such calculations are very useful, these calculations have not much to do with what we generally understand under AI…
