Emulsion Properties and Phase Equilibrium and of New Asymmetric Gemini Surfactants Consisting of Fatty Acid Esters of Polyethoxylated Alcohol or Phenol

摘要

The emulsion and phase properties of water-surfactant systems are reported for nonionic surface active compounds of the asymmetrical gemini type resulting from the esterification of a polyethoxylated alcohol and a fatty acid. These products exhibit typical gemini surfactant properties, in particular, low critical micelle concentration (CMC) and good emulsifying properties, and they often form a gel depending on the temperature and concentration.
