Is Isopropyl Linoleate natural?

Mostly. Linoleic acid comes from vegetable oil (natural); isopropanol used to form the ester is a petrochemical alcohol.

How we scored it

Linoleic acid acyl C18H31O 263.4 Da (natural) + isopropyl C3H7 59.1 Da (petrochemical, minus ester water) = 322.5 → 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

Made by esterifying linoleic acid, obtained from vegetable oils such as safflower or sunflower, with petrochemical isopropanol. Isopropanol has no significant natural cosmetic route.

In plain English

A lightweight emollient that softens and conditions skin. Made by combining linoleic acid from vegetable oil with isopropanol, a petroleum-derived alcohol.
