The low interfacial tension properties of pure sulfonates are discussed in terms of the alkane carbon number for min tension (n/sub min/) and the min interfacial tension (..gamma../sub min/). Effects of variables on n/sub min/ and ..gamma../sub min/ are studied. The alkylbenzene sulfonates are divided into three groups having distinct preference curves on ..gamma../sub min/ vs n/sub min/ plots for surfactant mixtures. Surfactants with a short methyl or ethyl group ortho to the sulfonate group and a longer alkyl chain in the meta position (e.g., sulfonated 5(p-ethylphenyl)dodecane) gave very low interfacial tension (<10/sup -2/ dyne/cm) against alkanes and crude oils. 7 figs.
