How we scored it

2x octadecyl (stearyl) C18H37O natural oleochemical fragments (539 Da) + thiodipropionate diacyl core C6H8O2S petrochemical (144 Da) → 539/683 = 0.79
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

Diester of stearyl (octadecyl) alcohol, typically from vegetable oil (e.g. palm or soy) or tallow, with thiodipropionic acid made from petrochemical acrylic acid and a sulfide source.

In plain English

An antioxidant that protects formulas from oxidation. It combines a plant- or tallow-derived stearyl fatty alcohol with a synthetic sulfur-containing acid.
