CEN - EN ISO 2871-1

Surface active agents - Detergents - Determination of cationic-active matter content - Part 1: High-molecular-mass cationic-active matter

active, Most Current
Organization: CEN
Publication Date: 1 February 2010
Status: active
Page Count: 12
ICS Code (Surface active agents): 71.100.40
scope:

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. distearyl-dimethyl-ammonium chlorides, or

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.
