Abstract

The change in the concentration of sodium dodecyl sulfate (SDS) can, in fact, affect directly the correlation between phase behavior and structure of a four-component system, polyethylene glycol/sodium dodecyl sulfate/pentanol/H2O. Experimental results indicate that the phenomena of microemulsion and lamellar liquid crystals can take place at a concentration of SDS greater than 5% and 17% by weight, respectively. In our experiments, these liquid crystals are tested and found to be hydrophilic and their rheological properties to be non-Newtonian as well.
