Surfactants prepd. by bromination of the double bonds of oleate groups of sorbitan monooleate (I), sorbitan trioleate (II), and polyoxyethylene derivs. of I and II were effective emulsifiers in the prepn. of oil-in-water emulsions. The HLB values of the brominated compds. were similar to those of starting compds. The use, formation, and the stability of emulsions were detd. [on SciFinder(R)]
