How we scored it

Adipic acid (petrochemical, cyclohexane oxidation) + 2x isodecanol (petrochemical branched oxo alcohol) -> 0/426.7 = 0.0
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

Diisodecyl adipate is made industrially from petrochemical adipic acid (via cyclohexane oxidation) esterified with synthetic branched isodecyl alcohol. No natural-origin route is commercially significant.

In plain English

A synthetic diester of adipic acid and branched isodecyl alcohol, made from petrochemical feedstocks. Used as an emollient and plasticiser to give a light, silky skin feel in creams and colour cosmetics, and to keep nail polish or plastics flexible.
