Phytic Acid as a chelate and pH…….
As is typical with pH sensitive ingredients….the vendors in their propaganda have steered well away from an ideal pH window….and use broad vaguisms for a range, like “effective over a wide pH range” which immediately alerts me to the fact….it is NOT!
ONLY Evonik dared tread where angels fear and posted this statement: “Best performance is shown at pH 6.“
Well…I rarely formulate…right at 6! I have never seen such a concise pH range (a single number). So….. does anyone have any material that delineates what the reasonably acceptable range would be where it still performs some serious chelation?
I am not looking for more marketing material…looking for something more along the line of science. 🙂
Aloha.

Complex Formation of Phytic Acid With Selected Monovalent and Divalent Metals
The formation of metal complexes with phytic acid is a complex process that depends strongly on the metal-to-ligand molar ratio, pH value and consequent protonation level of the phytate ligand as well as accompanying side reactions, in particular metal hydrolysis … Continue reading
