How we scored it
Ascorbic acid (glucose-derived) and protein-hydrolysate peptides are both natural; condensation leaves no foreign mass; 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 couples glucose-derived ascorbic acid to hydrolysed plant or collagen protein. Reagents leave no mass in the final product.
In plain English
A vitamin C derivative bound to short protein fragments, used as an antioxidant and skin conditioner. Vitamin C is made from sugar, and the peptides come from hydrolysed plant or animal protein.
CosIng definition: L-Ascorbic acid, reaction products with protein hydrolyzates
