The determination is carried out by argentometric titration after decomposition of a test and separation of fatty acids by filtration. The method is applicable to soaps having a chloride content, expressed as sodium chloride, equal to or greater than 0,1 % (m/m). It cannot be applied to componounded products.
Abstract
Overview
ISO 457:1983 - Soaps - Determination of chloride content - Titrimetric method specifies an argentometric (silver‑based) titration procedure for measuring chloride in commercial soaps. The method determines chloride as (or expressed as potassium chloride KCl) after decomposition of a soap test portion and separation of fatty acids by filtration. It applies to soaps with chloride content ≥ and is not applicable to compounded/composite products.
