How we scored it
Gluconic acid from glucose fermentation (196 Da) + Na+ mineral ion (23 Da); both 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.
How it’s made
Where it comes from
Produced by fermenting glucose (e.g. from corn) with Aspergillus niger to gluconic acid, then neutralising with sodium hydroxide/carbonate. No alternative petrochemical route is used commercially.
In plain English
The sodium salt of gluconic acid, made by fermenting glucose (e.g. corn sugar) and adding a mineral sodium component. Used to bind trace metals in a formula and to condition skin.
Structure
sodium (2R,3S,4R,5R)-2,3,4,5,6-pentahydroxyhexanoate
