The role of alcohols in microemulsion formation is primarily two-fold. They function as cosolvents by modifying surfactant partitioning between the aqueous and oleic phases and they function as cosurfactants stabilizing microemulsion to the exclusion

Isomer-free secondary alkane sulfonates' were synthesized from a series of pure secondary alcohols. The C-S bond was formed by thioesterification of the alcohol. A subsequent mild oxidation followed by neutralization generated the monoisomeric sodium

The self association of dodecane-1,12-bis(tributylammonium bromide) and of hexadecane-1,16-bis(trimethylammonium bromide) (C 12 Bu 6 and C 16 Me 6 , respectively) has been investigated by means of density, conductivity, emf, T-jump, and ultrasonic ab

The general phase behavior of selected alkyl benzene sodium sulfonates was studied with the aim of determining specific factors which will enhance solubilization of oil and/or water in microemulsions. In pursuing this, it was discovered that decreasi

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
