How we scored it
Pentacyclic triterpene extracted from plant sources (apple peel, herbs); no commercial synthetic route = 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
Extracted from apple pomace, loquat leaf or rosemary. No significant petrochemical synthesis route is used commercially.
In plain English
A skin-conditioning compound extracted from apple peels and certain herbs. It's a naturally occurring plant triterpene, obtained by extraction rather than chemical synthesis.
