Scope

This standard specifies a test method for determining the hydrolyzable and non-hydrolyzable anionic surfactants in detergents under acidic conditions.
This standard applies to surfactants such as alkyl sulfates, alkyl phenol ethersulfates, and fatty alcohol ethersulfates.
If the content of the surfactants is expressed as a mass fraction, the average molecular weight of the two types of surfactants must be known or predetermined. If the detergent contains oxidizing agents, they must be destroyed before hydrolysis.
