A series of sodium polyoxypropylated cyclohexyl and phenyl phosphates was synthesized. The change in their surface activities, such as lowering of surface tension, foaming properties, wetting power, dispersing power and emulsifying power, with variation of the number of moles of propylene oxide added was discussed. Influence of cyclohexyl and phenyl group attached to the end of hydrophobic group on the surface activities was also studied.<BR>The results obtained are as follows.<BR>The aqueous solution of cyclohexanol derivatives have lower surface tension than those of phenol derivatives, while the wetting power and dispersing power of phenol derivatives are superior than those of cyclohexanol derivatives. The foaming properties and emulsifying power of both derivatives are slight, and the lowering of surface tension, wetting power and dispersing power are improved by increasing the number of moles of propylene oxide added.
