How we scored it
CosIng description 'Melanins' indicates the natural tyrosine-derived pigment polymer; given formula (C18H10N2O4) appears mismatched to an unrelated discrete structure, so description trusted → 1.0.
What counts. ISO 16128-2 scores the atoms that remain in the final ingredient. Reagents, solvents, catalysts and protecting groups used during manufacture leave no mass behind and are not counted.
Where it comes from
Natural melanin is extracted from sources such as cuttlefish ink or produced by oxidative polymerisation of the natural amino acid tyrosine/DOPA. The supplied discrete-molecule formula does not match this polymeric pigment class.
In plain English
A natural pigment similar to the one that gives human skin and hair their colour, usually obtained by extraction or biological production from tyrosine. Used to help protect skin from the visible effects of sun exposure.
