How we scored it
Piperidine alkaloid; commercially extracted from black pepper fruit (5-9% content makes extraction economical) rather than synthesised, so it counts as natural.
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 black pepper (Piper nigrum) fruit. Total synthesis is known but is not the commercial cosmetic-ingredient route.
In plain English
The compound that gives black pepper its bite, used here as a skin-conditioning ingredient. It's extracted directly from pepper fruit.
