hydrophile nano-porous polyethersulfone membranes using synthesized poly(sulfoxideamide) as additive in the casting solution," Journal of Membrane Science, vol.
Emulgen 66 and Emulgen 90 are nonionic surfactants, and the
hydrophile:lipophile balance (HLB) of the combination was 13.5.
The onset of CAC and CMC are highly dependent on the actual structure of the surfactant molecule, size of hydrophobe and
hydrophile, as well as molecular weight.
This situation contrasts with the inverse emulsion process, where the hydrophobe is present in the continuous phase and the
hydrophile in the dispersed phase.
Attached to the organic hydrophobe is the
hydrophile, which is a water-soluble segment and often a polyether or acid salt.
