Query: Solubility limit of methyl red and methylene blue in microemulsions and
  liquid crystals of water, sds and pentanol systems   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.
