How we scored it

Ricinoleic acid (natural, castor oil) esterified with 2-octyldodecanol (Guerbet alcohol built from natural fatty alcohols). All carbons trace to natural feedstock. 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

Ricinoleic acid comes from castor oil; octyldodecanol is a Guerbet alcohol produced by catalytic dimerisation of natural fatty alcohols (e.g. from coconut/palm). Assumes cosmetic-grade Guerbet alcohol is oleochemical.

In plain English

A silky emollient ester used in skincare, made from castor oil fatty acid and a branched fatty alcohol derived from coconut or palm alcohols. Fully plant-derived under typical cosmetic-grade sourcing.
