Hi everyone am new here and into soap making.i would like to formulate with this
Palm oil
Coconut oil
Water
Sodium chloride
Titanium dioxide
Tetrasodium etidronate
Sodium citrate
Tetrasodium EDTA
I have disodium EDTA and sodium hydroxide,its difficult to get tetrasodium EDTA and etidronate in my country. How can I use disodium and NaOH to formulate tetrasodium EDTA and what can I use for etidronate.
And in my country we have more of hard water than soft water, what measurement of the additive can i use for this formular in a bathing soap. Thank you

If I'm not mistaken,
for every 372.24 g Disodium EDTA
https://www.sigmaaldrich.com/catalog/product/usp/1233009?lang=en®ion=US
add 2 moles Sodium hydroxide = 80.0 g

you'd get
380.17g Tetrasodium EDTA plus extra water from the reaction

As for etidronate
try a local pharmaceutical ingredients suppliers
or you'll need to import it yourself.
