How we scored it
Ascorbate (glucose fermentation) 1.0 + glyceryl (glycerin; glyceryl groups natural) 1.0 + caprylyl C8 (coconut/palm-kernel caprylic acid or octanol) 1.0; all fragments natural origin; 1.0.
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
Dominant route: ascorbic acid (from glucose) is coupled with glycerin and a caprylyl chain from coconut or palm-kernel oil to give the glyceryl ascorbate derivative. Supplier note: petrochemical octanol or 1-octene based C8 chains exist but are assumed not to be used, and the exact structure is not given in CosIng.
In plain English
An oil-friendly form of vitamin C in which ascorbic acid is linked to glycerin and a caprylyl (C8, coconut-type) fatty chain. It is used as an antioxidant and humectant.
