Summary A semi‐micro procedure for the determination of borax in soap has been develped based on the fact that strontium metaborate is soluble in an excess of strontium chloride solution, whereas both strontium orthophosphate and silicate are quantitatively precipitated. The strontium metaborate is acidified and the liberated boric acid titrated to α‐Naphtholphathaleint in the presence of mannitol.
