  • How much is a cationic surfactant worth?
  • The total value of cationic surfactants produced today (2023) is around 2 billion US dollars, which is less than 5 % of the total market value of surfactants. Anionic and nonionic surfactants together account for almost 95 %. The fourth class of surfactants, zwitterionics, represents only around 1 % of the total surfactant market.
  • Which cationic surfactants are self-assembly?
  • Single-chain surfactants Considering the cationic surfactant self-assembly, we will focus on the quaternary ammonium surfactants (quats), for which, by far, most information is available. Single alkyl chain quats with inorganic counterions behave very much like other polar surfactants, i.e. those with a CPP value of 1/2 , .
  • How effective is flocculation in highly turbid water clarification?
  • Flocculation performance and kinetics were investigated in highly turbid water clarification. Most effective flocculation occurred at pH 4 with the flocculant which contained the highest cationic content. Flocculation and mechanism was discussed based on zeta potential and pH analysis.
  • Are cationic surfactants better than specialty surfactant?
  • Cationics have more the character of specialty surfactants and most of their uses are based on the fact that the majority of surfaces carry a net negative charge to which the positively charged surfactants readily adsorb.
