How we scored it
Aspartic acid (amino acid, fermentation/protein-hydrolysate-derived, natural) + Zn2+ (natural mineral counter-ion). All atoms natural.
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 neutralizing fermentation- or hydrolysate-derived aspartic acid with a zinc mineral source. Both fragments are natural origin.
In plain English
A mineral salt combining zinc with aspartic acid, an amino acid derived from proteins. Used as a skin-conditioning ingredient in cosmetic formulas.
