Abstract: A mixture of two alkoxylates surfactants, one being an aryl aliphatic carbinol alkoxylate, the other one being a dialiphatic carbinol alkoxylate, said mixture being useful for stabilizing emulsions and dispersions used in agricultural or pharmaceutical formulations. The alkoxylates surfactants may serve as substitutes for nonylphenol ethoxylates (NPE) and tristyrylphenol ethoxylates (TSE).
