100% petroleum · ISO 16128

Is Benzophenone-10 natural?

No. Both aromatic rings derive from benzene and toluene, and the methoxy carbon from methanol, so no fragment has a natural-origin feedstock.

How we scored it

C15H14O3 242.27 Da: methoxyhydroxyphenyl ring, tolyl ring, carbonyl and methoxy all from petrochemical benzene, toluene and methanol. Natural 0 / 242.27 = 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 acylating a methoxy-hydroxyphenyl compound with a p-toluoyl derivative, all from petrochemical aromatics. No natural-origin route is in commercial use.

In plain English

A synthetic ultraviolet-absorbing chemical (also called mexenone) from the benzophenone family. It absorbs UV light, so it is used in sunscreens and to stop products breaking down in light. It is made in a chemical plant from petroleum-derived aromatic compounds.
