How we scored it
Natural olive phenolic; isolated and purified from olive vegetation water, retaining all atoms of the natural molecule, so 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
Recovered from olive mill vegetation water and olive leaves, a byproduct stream of olive oil production, by extraction and purification. A minor chemical or biocatalytic synthesis route also exists.
In plain English
A potent antioxidant naturally found in olives and olive oil, used to protect skin from environmental damage. It's recovered from the water left over after pressing olives for oil.
