Surface active agents - Detergents - Determination of cationic-active matter content - Part 1: High-molecular-mass cationic-active matter
|Publication Date:||1 February 2010|
|ICS Code (Surface active agents):||71.100.40|
This part of ISO 2871 specifies a method for the determination of high-molecular-mass cationic-active materials such as
a) quaternary ammonium compounds in which two of the alkyl
groups each contain 10 or more carbon atoms, e.g.
b) 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.
