How we scored it

2xNaSO3 mineral fragment = 206.1 Da (natural per sulfate/sodium convention); C28H20 distyrylbiphenyl backbone = 356.5 Da (petrochemical, benzene-derived); 206.1/562.6 = 0.37.
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

A synthetic optical-brightener built from petrochemical biphenyl/stilbene chemistry, sulfonated and neutralised with sodium. No natural-origin route exists for the aromatic backbone.

In plain English

A synthetic brightening ingredient built from a petrochemical biphenyl structure, used in hair and cleansing products to boost shine or absorb UV.
