A very helpful review from George of Dawn Organics:

A very good non drying chelator in soap, great citric acid substitute for shampoo, facial and body cold process soap bars. Very effective at reducing soap scum at 1%. You add this to the water before adding the Lye. For cleaning soap it's a good idea to use with citric acid, dermofeel (Sodium Phytate) & Sodium Gluconate for a triple chelating action. All three work harmoniously to clean your dishes very well without leaving any soap scum residue on your dishes and surfaces. If you have really hard water, it wipes off very easily. If using with Citric acid, be sure to add the sodium gluconate and Sodium Phytate at light trace, dissolve them in distilled / spring water then add. Citric acid can react with them, so best for the reaction to happen in the lye pot to make sodium citrate, be sure to refer to your lye calculator so you know how much extra lye you need to add.

If using in cleaning liquid soap, Sodium Gluconate & Sodium Phytate can be added after you have diluted your liquid soap paste
