Tetrasodium EDTA is recommended for alkaline products such as foaming soap. EDTA works synergistically with your preservative to improve preservative efficacy. In soaps, it can counteract the defoaming action of hardness ions, reducing soap scum and improving lather. It is useful in formulating dry where the total water content of a product must be kept to a minimum. It can also be used to neutralize Carbomer, or raise the pH of personal care formulations.
The key difference between disodium EDTA and tetrasodium EDTA is that disodium EDTA has a pH lower than 7 while tetrasodium EDTA has a pH greater than 7.
Disodium EDTA is better suited in creams, lotions, hair conditioners.
