Effect of the hydrophobic chain length on the surface activity was investigated for the following two types of oil-soluble organo boron surfactant. (I) (II) It was observed for both types that the shorter the hydrophobic chain lengths of surfactants was, the better the interfacial tension lowering ability became in the alkyl range of C11C21. Monoester type (I) had better interfacial tension lowering ability than diester type (II) in lower concentration region, but no difference in the surface activity was observed between (I) and (II) in the higher concentration region. The result was discussed on the basis of Π-A curves of type (I) and type (II).
