How we scored it
Purine base C5H5N5; cosmetic-grade material is made by microbial fermentation, same feedstock class as adenosine. 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
Cosmetic-grade adenine is produced by microbial fermentation of sugar feedstocks. A laboratory HCN-based chemical synthesis exists but has no meaningful commercial cosmetic-ingredient supply share.
In plain English
Adenine, sometimes called vitamin B4, is a building block of DNA and RNA used to condition skin. It's produced by fermenting sugars with microorganisms.
CosIng definition: Vitamin B4
Structure
7H-purin-6-amine
