Surface active agents. Detergents. Determination of cationic-active matter content -- High-molecular-mass cationic-active matter
This part of ISO 2871 specifies a method for the determination of high-molecular-mass cationic-active materials such as:
The method is applicable to solids or to aqueous solutions of the active material when the relative molecular mass of the cationic-active matter is known or when it has been previously determined if its content is expressed as a percentage by mass.
The method is not applicable if anionic surface active agents are present.
