“…The hydrophilic end consists of polar bonds and is soluble in water, whilst the lipophilic end is soluble in oil [8]. Frequently-used emulsifiers in lubrication technology are nonionic surfactants [9]. Researchers have conventionally attributed emulsion effectiveness to the idea that droplets 'plate out' onto exposed metal surfaces [10].…”

“…Until now a few types of surfactants which would satisfy the above requirements have been reported: betaine ester (cationic) [5][6][7], ortho ester (nonionic, cationic, etc.) [8,9], and acyclic acetal (anionic) [10]. These surfactants decompose promptly at room temperature in weakly acidic or basic solution.…”

Alkylaldehyde-bisulfite adducts with octyl, decyl, and dodecyl groups (C n S: n=8,10,12) were synthesized and the surface-active properties of the water-soluble compounds were compared. Exchange of the counter anions of C 10 S and C 12 S from sodium to tetramethylammonium solubilized them in water. The latter ammonium salt (C 12 S-QA) had surface activities as good as a classical surfactant, sodium dodecylsulfate, and dissociated promptly in weakly basic solution at room temperature to be a non-surfactant. It was also found that C 12 S-QA solubilized a hydrophobic substrate (solid), N,N-dimethyl-3-nitroaniline, in water and then separated it as a precipitate after alkali treatment.

“…Recently, nonionic ortho ester surfactants have been used as emulsifiers for squalene, a polar oil [65]. In this case a polymer is used together with the surfactant.…”
