How we scored it
Undecylenic acid (castor-oil derived) + glycine (fermentation amino acid); condensation water/HCl not counted → 1.0.
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
Produced by acylating glycine with undecylenic acid, obtained by pyrolysing ricinoleic acid from castor oil. No significant petrochemical route exists.
In plain English
A deodorant, anti-microbial ingredient combining castor-oil-derived undecylenic acid with the amino acid glycine. Used in deodorants and scalp products to help manage odour and oiliness.
