Abstract:

A series of novel surfactants, i.e. salts of fatty alcohol polyoxyethylene ether succinates with different ethylene oxide (EO) numbers (AEnCE-Na, n=3, 5, 7, 9), were studied by measurement of equilibrium surface tension, dynamic surface tension, contact angle as well as the evaluation of application performance in wetting, emulsifying, foaming and detergency. The results showed that, AE3CE-Na not only exhibited the highest efficiency and ability to reduce the surface tension of solutions, but also showed the best wettability on the paraffin film. The diffusion rate of AEnCE-Na with different EO numbers were all fast. In terms of application performance, AE3CE-Na showed the best wetting, emulsifying (including liquid paraffin and soybean oil) and foaming properties, while AE9CE-Na showed the best detergency and foam stability.

Key words: fatty alcohol polyoxyethylene ether succinate, surface tension, contact angle, application properties
