How we scored it

Brominated glutaronitrile preservative built from petrochemical nitrile precursor; fully synthetic, no natural fragment.
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

Produced by brominating synthetic methylglutaronitrile, itself derived from petrochemical acrylonitrile-type chemistry. No natural-origin route exists for this preservative.

In plain English

A preservative that inhibits microbial growth in cosmetic formulas. It is a fully synthetic brominated compound manufactured from petrochemical nitrile precursors.
