Is Diisopropyl Dimer Dilinoleate natural?

Mostly. Dimer dilinoleic acid is built from two natural linoleic acid molecules; the isopropyl ester groups are petrochemical.

How we scored it

Dimer diacyl (from linoleic acid dimer, ~C36H64O4, ~527Da, natural) + 2x isopropyl C3H7O (~118Da, petrochemical) = ~645Da. 527/645 = 0.82.
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

Dimer dilinoleic acid is made by thermally dimerizing linoleic acid from vegetable oils (e.g., soybean, tall oil). It is esterified with petrochemical isopropanol.

In plain English

A lightweight emollient oil that conditions skin without feeling heavy. It's made by linking isopropyl alcohol (petroleum-derived) to dimer dilinoleic acid, built from two natural linoleic acid molecules from vegetable oil.

CosIng definition: Diisopropyl Dimer Dilinoleate is the diester of isopropyl alcohol and Dilinoleic Acid
