Uses of Cationic Surfactants


Fatty Amine Salts

The principle uses of the fatty amine salts are in ore-flotation, corrosion ihibition and wetting. They are rarely marketed on their own, rather in propritery formulations.

Quaternary Ammonium Salts and Alkyl Pyridinium Halides

The development of the pH insensitive cationic surfactants allowed much wider use of this technology. The quaternary amine is a strong hydrophile, making these good surfactants. They are primarily used in domestic fabric-softeners, as the positively charged hydophilic head tends to interact strongly with negatively charged fabric fibres.
