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 |
|---|---|---|---|---|
| Octylamine from coconut or palm kernel caprylic acid via nitrile, condensed with butyrolactone | C8 chain oleochemical; ring and nitrogen petrochemical | 0.57 | est. 55%, presumed dominant | |
| Octylamine from synthetic n-octanol or octene, condensed with butyrolactone | fully petrochemical | 0.00 | est. 45% |
How we scored it
Where it comes from
Dominant route is presumed to react oleochemical n-octylamine (coconut or palm kernel caprylic acid via the nitrile) with butyrolactone, but this is uncertain. Petrochemical octylamine from synthetic octanol is a significant alternative.
In plain English
A cleansing, foaming and conditioning surfactant: a small ring-shaped amide (pyrrolidone) carrying an eight-carbon chain. The ring is built from petrochemical butyrolactone and the chain from octylamine, made from coconut caprylic acid or from petrochemicals.
