The effects on surface activities by mixing the sodium stearyl and oley' sulfates were studied. <BR>(1) The solubility of stearyl sulfate in water increased by mixing of oleyl sulfate. <BR>(2) The mixture showed double kraft points and their position shifted with the amounts of oleyl sulfates. <BR>(3) There was not so much difference between the surface-tension of each solutions in relatively higher concentrations, but in dilute solutions (below 0.03 %) surface-tension became higher as oleyl sulfate content increased. <BR>cmc-Values of both sulfates estimated from conductivity method and surface-tension method were not so differed. <BR>(4) Carbon dispersing abilities of 0.05 % concentration were same, but in the case of 0.1 % solution the mixture showed higher abilities than solitary solutions.
