- Scope
- This standard specifies the method for the determination of cationic active substances in surfactants and detergents. This standard is applicable to the determination of cationic active substances such as: a) mono-, di-, tri-fatty alkyl tertiary amine quaternary ammonium salt, methyl sulfate quaternary ammonium salt; b) long-chain amidoethyl and alkyl imidazolinium salts or 3- Methylimidazolinium salts; c) amine oxides and alkylpyridinium salts. This standard applies to solid active substances or active substance aqueous solutions. If its content is represented by mass fraction, the average relative molecular mass of the cationic active substance must be known or determined in advance. This standard does not apply to the determination in the presence of anionic or amphoteric surfactants. Nonionic surfactants, soaps, urea and EDTA did not interfere. Typical inorganic components of detergent formulations, such as sodium chloride, sodium sulfate, sodium tripolyphosphate, sodium borate, sodium perborate, sodium silicate, etc. do not interfere. However, bleaches other than perborate should be pre-destroyed prior to analysis.
