Why the score varies
This ingredient is made commercially by more than one route, and ISO 16128 scores the feedstock actually used. Without a supplier certificate of origin the value cannot be claimed.
| Route | Feedstock | NOI | Share | Notes |
|---|---|---|---|---|
| natural chlorophyll hydrolysis | plant chlorophyll | 1.00 | unclear | |
| petrochemical total synthesis | petrochemical building blocks, vitamin E/K intermediate route | 0.00 | unclear, large volume in vitamin synthesis |
How we scored it
Where it comes from
Phytol is a side-chain fragment of chlorophyll and can be obtained naturally by hydrolysing chlorophyll from plant biomass. Large volumes are also made synthetically from petrochemical feedstocks as an intermediate for vitamin E and K1.
