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 |
|---|---|---|---|---|
| Oxo/petrochemical C5-9 acid cut esterified with petrochemical dipentaerythritol | propylene/butene oxo acids; acetaldehyde + formaldehyde | 0.00 | ~60% (estimate) | |
| Oleochemical C5-9 acids (castor heptanoic, coconut caprylic, oleic-derived pelargonic) esterified with petrochemical dipentaerythritol | castor oil, coconut oil, oleic acid; acetaldehyde + formaldehyde | 0.73 | ~40% (estimate) |
How we scored it
Where it comes from
Dominant route is assumed to be esterification of petrochemical dipentaerythritol with a C5-9 acid cut from oxo (propylene/butene) chemistry, common in synthetic polyol esters. The alternative uses oleochemical acids (castor heptanoic, coconut caprylic, oleic-derived pelargonic).
In plain English
A thick, glossy ester oil that adds gloss, cushion and slip to lipsticks, balms and creams and helps soften polymers. It is made from dipentaerythritol, a petrochemical polyol, esterified with a mix of short-to-medium chain fatty acids (C5 to C9).
