How we scored it
2x gluconate C6H11O7 (fermentation, natural) + Mg (mineral, natural) + 2H2O (natural) = C12H26MgO16 dihydrate; all natural. 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
Made by fermenting glucose to gluconic acid and neutralising with a magnesium source, crystallised as the dihydrate. Both fragments and the water of hydration are natural origin.
In plain English
The magnesium salt of gluconic acid, a mild acid made by fermenting sugar. Used as a skin-conditioning ingredient in formulas.
Structure
magnesium;bis((2R,3S,4R,5R)-2,3,4,5,6-pentahydroxyhexanoate);dihydrate
