DESCRIPTION
BS EN ISO 2871-1:2010
This standard BS EN ISO 2871-1:2010 Surface active agents. Detergents. Determination of cationic-active matter content is classified in these ICS categories:
- 71.100.40 Surface active agents
This part of ISO 2871 specifies a method for the determination of high-molecular-mass cationic-active materials such as
quaternary ammonium compounds in which two of the alkyl groups each contain 10 or more carbon atoms, e.g. distearyl-dimethyl-ammonium chlorides, or
salts of imidazoline or 3-methylimidazoline in which long-chain acylaminoethyl and alkyl groups are substituted in the 1- and 2-positions, respectively.
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.
