How we scored it
C18 branched fatty alcohol, assumed oleochemical (from isostearic acid) per the C8-C22 default; supplier note for a possible Ziegler/oxo route.
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
Typically produced by reducing isostearic acid, which is made by dimerising and isomerising natural oleic acid. A minor petrochemical (Ziegler/oxo) route exists; verify with supplier if a natural claim is needed.
In plain English
A branched fatty alcohol usually made from vegetable-oil-derived isostearic acid. It conditions skin and hair and thickens the texture of creams and lotions.
Structure
16-methylheptadecan-1-ol
