How we scored it

CAS 134-84-9 is 4-methylbenzophenone, C14H12O 196.2: benzene and toluene rings are petrochemical; 0 / 196.2 = 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

Made by Friedel-Crafts acylation of toluene with benzoyl chloride, both from petrochemical aromatics. No natural-origin route is commercial.

In plain English

A benzophenone-type light stabilizer, used to help protect a product's colour or scent from light. It is made entirely from petrochemical benzene and toluene.
