RS ISO 456: 1973
Surface active agents — Analysis of soaps — Determination of free caustic alkali
Abstract

As soaps usually contain a small amount of unsaponified
neutral fat, there is no perfect procedure for determining
free caustic alkali because, when the sample of soap is
dissolved, a neutral fat is more or less saponified by any
free caustic alkali that is present.
