the right form of EDTA salt for dishwashing liquid
Dear members, chemists, I’m delighted to be a member on this platform and as a first timer I found most of things discussed here helpful. I’m about to venture into dishwashing liquid business but I need your suggestions on the formula I intend to use. Also I need to be sure of the form of EDTA to be use but I have bought Disodium EDTA salt. Below is the formula for 1liter capacity.
LABS 94 mlSles. 30mlCaustic soda 12.5gNaCl. 2gEDTA 1gFormalin 1gDistilled water 860ml -

From Lotion Crafter web-site.
Summary, MORE OR LESS:
acidic pH, use disodium EDTA
basic pH use tetrasodium EDTAGenerally, the choice of which product to use is determined by the pH of your product, but this is not a hard and fast rule. Disodium EDTA is commonly used in neutral to mildly acidic products, like most creams, lotions, and neutral pH liquid soaps and shampoos.
Generally, the choice of which product to use is determined by the pH of your product. Tetrasodium EDTA is recommended for alkaline products, like most handcrafted soap. It can also be used in creams, lotions and surfactant systems. -
I believe citric acid displaces the weaker EDTA acid,
so tetrasodium becomes disodium EDTA at lower pH levels. -
First of all, I will like to appreciate your responses. They are really informative. Based on what Margaret said I think tetrasodium is preferable bcos if I may be right the pH for dishwashing liquid is around 7-8.
