Is Retinyl Sunflowerseedate natural?

Mostly not. Sunflower seed fatty acids are vegetable-oil derived, but retinol is made by petrochemical synthesis, so only the fatty acyl half counts as natural origin.

How we scored it

Sunflower acyl (~64% linoleoyl, ~23% oleoyl) average ~262.5 natural; retinyl-O C20H29O 285.5 petrochemical; total ~548; 262.5/548 = 0.48 (retinyl palmitate calibrates to 0.46).
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

Dominant route: synthetic retinol esterified with fatty acids from sunflower seed oil. Alternative: none significant, as natural or fermentation retinol is not a commercially significant cosmetic supply.

In plain English

A vitamin A (retinol) ester used to condition skin. It joins retinol, which is made synthetically, to the mixed fatty acids of sunflower seed oil, mostly linoleic acid.

CosIng definition: Retinyl Sunflowerseedate is the ester of Retinol and Sunflower Seed Acid.
