How we scored it
Al(C3H5O3)3: 3x lactate (fermentation-derived, natural) + Al (mineral counter-ion, natural). C9H15AlO9 = 294.19 Da, all natural. 294.19/294.19 = 1.00.
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 neutralising fermentation-derived lactic acid with an aluminum mineral source. There is no distinct petrochemical route, since both the acid and the metal ion are natural-origin under ISO 16128.
In plain English
Aluminum lactate is a mineral salt of lactic acid, used in deodorants for its astringent, sweat-reducing properties and as a pH buffer in other formulas.
Structure
