I want to dilute and neutralize excess potassium hydroxide from liquid soap paste but can not currently access citric acid or 'borax' in my current location. People only sell a white substance labelled "Bórax Decahidratado" [or Borax Decahydrate in English]. Its ingredient list says: 99.9% sodium borate decahydrate and suggested uses include water-based pH regulator.

If so, between 'borax' or 'boric acid', which is this Borax Decahydrate the same substance? Eager to know so I can decide the correct concentration of the neutralization solution (33% or 20%).

Otherwise, if it can be used to neutralize KOH from liquid soap paste, at what solution concentration?
It's borax, according to the 20 Mule Team borax website.
