Determination Of Water Content in Cleaning Products

Within the scope of the ISO 4317 standard, the amount of water in cleaning products such as surfactants and detergents is determined. Karl Fischer method is used within the scope of the standard. It can be applied to cleaning products in powder, paste and solution form. The amount of water in detergents and surfactants must be analyzed for the presence of alkali metal salts.

Two titration methods are carried out using the Karl Fischer reagent:

• Volumetric titration method – Water content 2% or more
• Coulometric titration method - If water content is 0.1% or less

Amount of Water within the scope of the Standard; It is defined as the mass ratio of free water, crystallization water, absorbed water or blocked water calculated from the amount of Karl Fischer reagent.
