Abstract A series of di‐anionic cleavable surfactants were prepared by the condensation of aldehydes with 2,2‐ bis (hydroxymethyl)‐1,3‐propanediol, followed by reaction with 1,3‐propanesultone in the presence of sodium hydride. Surfactant 5a had a different 1 H nuclear magnetic resonance spectrum in D 2 O than products 5b−d. This was rationalized by its different conformation, which originates from the self‐coiling of its alkyl chain. The critical micelle concentrations, Krafft points and hydrolysis properties of these surfactants were determined.
