Increased hydrophobe branching is employed to increase water solubility of surfactants. This is often considered synonymous with increasing surfactant HLB. When HLB is viewed in the context of the phase behavior of oil/water/surfactant systems, it is

The synthesis and low interfacial tension behavior of a variety of di- and trialkylbenzenesulfonates are described. The benzene ring carries one major alkyl substituent, consisting of a linear chain eight to sixteen carbon atoms long, and one or two

The synthesis of several di and tri n-alkylbenzene-sulfonates is described. Low interfacial tensions can be obtained against alkanes by using these materials as surfactants. The low interfacial tension properties of these surfactants are shown to be

Several surface tension and micellar solution thermodynamic properties of some N,N-bis-(2-hydroxyethyl) amides have been determined and compared with those of other nonionic surfactants. The ADEA's, which have never before been investigated, were fou

The ability of surfactants to generate ultra-low (10/sup -2/ to 10/sup -5/ dynes/cm) interfacial tensions (lift) in oil/water systems has received increasing attention in recents years. To date, however, no one has successfully correlated lift behavi
