Is Ascorbyl Linoleate natural?

Yes. Ascorbic acid is made from glucose by fermentation and linoleic acid comes from safflower, sunflower or similar vegetable oils; esterification leaves no foreign atoms.

How we scored it

Ascorbic acid (from glucose) 176.1 + linoleic acid (vegetable oil) 280.5 - H2O 18.0 = 438.6 Da; both fragments natural: 438.6/438.6 = 1.00.
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

Ascorbic acid from corn or wheat glucose via fermentation is esterified with linoleic acid from safflower or sunflower oil. No significant petrochemical route exists.

In plain English

A fat-soluble form of vitamin C made by joining ascorbic acid to linoleic acid, a fatty acid from vegetable oils. Used as an antioxidant and skin-conditioning ingredient in oil-based and leave-on products. The ascorbic acid is made by fermenting glucose.
