Physicochemical and application properties of C13-branched alcohol ethoxylates (BAEO) with different ethylene oxide addition numbers

Branched alcohol ethoxylates (BAEO) are environmentally friendly non-ionic surfactants with excellent performance. They have excellent permeability, emulsification, foam, detergency, and are the best substitute for nonylphenol surfactants. In this paper, C13-BAEOn with different EO additions numbers (n = 3,5,7,9) were synthesized by using C2H5ONa as the catalyst, and the physicochemical properties and application performance of C13-BAEOn with different ethylene oxide additions were systematically investigated.
