Abstract

Solubility of dyes in amphiphilic association structures of water, SDS and penthanol system (i.e. in the phases of microemulsions and liquid crystals) was attracted much interest due to its wide industrial and technological applications. This research was focused on understanding the solubility limitation of methyl red and methylene blue in microemulsion and liquid crystal phases. Experimental results showed that the highest solubility of methyl red was in LLC, followed by w/o microemulsion and o/w microemulsion, respectively, whereas the highest solubility of methylene blue was in w/o microemulsion, followed by o/w microemulsion and LLC, respectively. Hence, a chemical dynamics strongly played an important role in the solubility limitation of methyl red and methylene blue in microemulsions and liquid crystal phases.
