How we scored it

Sebacic acid (castor oil, natural) diacyl fragment 168 Da + 2x butanol-derived fragment (synthetic, 73 Da each = 146 Da) -> 168/314 = 0.53.
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

Sebacic acid from castor oil is esterified with n-butanol, an oxo-process petrochemical alcohol. No natural-origin route exists for the butanol portion.

In plain English

An emollient, plasticiser and fragrance ingredient made from sebacic acid, derived from castor oil, esterified with butanol. The acid portion is plant-derived; the butanol is typically petrochemical.
