EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ISO 4314 testing. This International standard specifies a titrimetric method for the determination of free alkalinity or free acidity of surfactants.
This method is valid only if it is specified in the specific standard for each product. Titrate the ethanolic or propanolic solution of the product with standard volumetric potassium hydroxide or hydrochloric acid or sulfuric acid solution, as appropriate, in the presence of phenolphthalein as an indicator.
During analysis, use only accepted analytical grade reagents and only distilled water or water of equivalent purity.
Gently reflux the selected solution for 5 minutes to remove carbon dioxide. Cool to ambient temperature and neutralize with potassium hydroxide solution in the presence of phenolphthalein solution until the indicator turns pink.
