Is Benzophenone-7 natural?

No. The rings and carbonyl come from petrochemical benzene and phenol, and the carbon-bonded chlorine is part of the petrochemical framework; no natural or mineral fragment is present.

How we scored it

C13H9ClO2 232.66: both aromatic rings and the carbonyl come from benzene and phenol, aryl-bonded chlorine counts as petrochemical, and there is no ionic or mineral part; 0 / 232.66 = 0.00.
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

Made by Fries rearrangement of 4-chlorophenyl benzoate, built from petroleum benzene, phenol and chlorine. No natural-origin route exists.

In plain English

A synthetic UV-absorbing compound that soaks up ultraviolet light, used to protect products from light damage. It is made from petroleum-derived benzene and chlorinated phenol.
