How we scored it

Condensation of urea + allantoin + formaldehyde; all feedstocks petrochemical/natural-gas derived → 0/total = 0.0.
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

Manufactured by condensing urea, allantoin and formaldehyde, all produced from natural gas and petrochemical intermediates. There is no commercial natural-extraction route for this preservative.

In plain English

A preservative that stops bacteria and mould growing in cosmetic formulas, extending shelf life. It is manufactured by reacting urea with other synthetic chemicals derived from natural gas and petrochemicals, not from any plant or animal source.
