How we scored it

Reaction product of urea with formaldehyde-derived hydroxymethyl groups; all fragments 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 from urea and formaldehyde in a multi-step condensation, the same petrochemical and natural-gas feedstock family as related urea preservatives. No natural route is used commercially.

In plain English

A preservative that protects cosmetic products from bacterial and fungal contamination. Like related urea preservatives, it is manufactured from synthetic petrochemical starting materials, not derived from plants or animals.
