This International Standard specifies a method for the deter-mination, in detergents, of anionic-active matter hydrolyzable and non-hydrolyzable under acid conditions.
This active matter includes alkyl sulfates and hydroxysulfates and alkylphenol and fatty alcohol ethoxysulfates.
The mean relative molecular mass of the two types of active matter must be known or previously determined, if their con-tent is expressed as a percentage by mass. If the detergent con-tains perborate, this must be destroyed before the hydrolysis.
