Influence of alkyl chain length compatibility on microemulsion structure and solubilization
The water solubilization capacity of water/oil microemulsions is studied as a function of alkyl chain length of oil (C/sub 8/ to C/sub 16/), surfactant (C/sub 14/ and C/sub 18/ fatty acid soaps), and alcohol (C/sub 4/ to C/sub 7/). Sodium stearate and sodium myristate were used as surfactants. For n-butanol microemulsions the maximum amount of water solubilized in the microemulsion decreased continuously with increasing oil chain length; for n-heptanol it increased continuously. For n-pentanol and n-hexanol systems, water solubilization reached a maximum when the oil chain length plus alcohol chain length was equal to that of the surfactant. The electric resistance and dielectric constant of the microemulsions also are measured as a function of alkyl chain length of the oil. 48 references.
