Is Undecylenyl Alcohol natural?

Yes. The C11 chain and terminal double bond originate entirely from castor oil ricinoleic acid via pyrolysis, a standard oleochemical route.

How we scored it

Undec-10-en-1-ol from castor-oil-derived undecylenic acid (pyrolysis of ricinoleic acid) reduced to alcohol; all carbons castor-oil-derived. 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

Produced by pyrolytic cracking of castor oil's ricinoleic acid to undecylenic acid, then reduction to the alcohol. This castor-oil route is the standard commercial source; no significant petrochemical alternative is used.

In plain English

A conditioning fatty alcohol used in skin and hair products, also valued for antimicrobial properties. It's derived from castor oil through a well-established plant-oil cracking process.
