摘　　要：The surface activity of the mixture, formed by sodium dodecylpoly oxyethylene sulfate (C12E7S) and dodecyltrihydroxyethylammonium chloride (C12NE), is much higher than that of the single one. The interaction between C12E7S and C12NE is very strong. The aquepus solution of C12E7S-C12NE is homogeneous. The solubilization of 1-pentanol by the aquous solutipn of C12E7S-C12NE is decrease when the mixed ratio approach 1∶1 and the solubilized curve is "V" type, in which the lowest solubilization is only about one third of the single one’s. The solubilization curve of n-hexane shows the maximum when the mixed ratio approach 1∶1.The surface activity of the mixture, formed by sodium dodecylpoly oxyethylene sulfate (C12E7S) and dodecyltrihydroxyethylammonium chloride (C12NE), is much higher than that of the single one.
