Introduction to standards:

This standard specifies the method for determining the free caustic content in soap using the anhydrous ethanol method. This standard applies to sodium soaps of ordinary fatty acids (measured in NaOH), not to potassium soaps or compound soaps. Generally, free caustic refers to sodium hydroxide (NaOH) for sodium soaps and potassium hydroxide (KOH) for potassium soaps.
