All the activities and physical properties including surface tension, foaming power, foam stability, emulsifying power, dispersion effect, wettability and solubilization of sodium dodecyl polyoxyethylene ${\alpha}$-sulfo alkanoates aqueous solution were measured and critical micelle concentration was evaluated. Their cmc ebaluated by the surface tension method was $10^{-4}{\sim}10^{-5}mol/{\ell}$, and surface tension of the aqueous solution was decreased to 30~70dyne/cm. The experimental results for foaming power, foam stability, emulsifying power in benzene or soybean oil, dispersion effect in calcium carbonate, wettability and solubilization showed a good and efficient surface active properties, and then it would be expected that these products could be applied as O/W type emulsifier, dispersion agent.
