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 |
|---|---|---|---|---|
| Petrochemical epoxidation | 1-decene (ethylene oligomerization) | 0.00 | believed majority, unconfirmed | |
| Oleochemical reduction | capric acid from coconut/palm kernel oil | 1.00 | believed minority, unconfirmed |
How we scored it
Where it comes from
Commonly manufactured by epoxidation/hydrolysis of petrochemical 1-decene, an established industrial route believed to dominate cosmetic supply. A smaller share is produced from natural capric acid (coconut or palm kernel oil) via reduction.
In plain English
A skin-conditioning ingredient that also helps preservatives work better. Depending on the manufacturer, it is made either from natural coconut or palm kernel oil fatty acid, or from a petrochemical building block processed into the same molecule.
