How we scored it

Pentanedial (glutaraldehyde) made industrially from acrolein via petrochemical synthesis; no commercial natural route. 0/100.12 = 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

Glutaraldehyde is manufactured industrially from acrolein or via oxidation of cyclopentene, both petrochemical routes. No natural or bio-based production route is used commercially.

In plain English

A synthetic dialdehyde used as a preservative and fragrance ingredient in cosmetics. It is manufactured industrially from petrochemical feedstocks such as acrolein, not derived from plants or animals.

CosIng definition: Glutaral is the dialdehyde that conforms to the formula:
