This standard specifies methods for the determination of hydrolyzable and non-hydrolyzable anionic active substances in detergents under acid conditions. These active substances include alkyl sulfates, hydroxysulfates, alkylphenols and fatty alcohol ethoxy sulfates. Active substances To express the content as mass percentage, the average relative molecular weight of the two active substances must be known or measured in advance. If synthetic detergents contain oxidizing agents, they must be decomposed before hydrolysis.?
