METHOD OF TEST FOR DETERMINATION OF TOTAL ANIONIC DETERGENT BY HYAMINE TITRATION
This Malaysian Standard describes a method for the determination of anionic detergent by
Hyamine titration. It is applicable to the analysis of alkylbenzene suiphonates, alkylsulphonates,
alkylsulphates and hydroxylsuiphates, alkylphenolethoxysulphates and fatty alcohol
ethoxysulphates in detergent liquids, powders or household cleaners.
The total active detergent is determined if a mixture of sulphonates and/or sulphates is present
(see note 1). The mean molecular weight of the active detergent(s) must be known. Sulphonates
with low molecular weight such as toluene and xylene sulphonate do not interfere when present
in concentrations up to 15% of active material.
