With　n-hexanol　as　cosurfactant,　quaternary　ammonium　Gemini　surfactants　C-12　center　dot　EOx-C-12　center　dot　2Br　(x　=　1,2,3)　formed　reverse　micelles　in　n-heptane.　The　critical　reverse　micelle　concentrations　(cmc(h))　were　determined　using　the　absorption　spectrum　method　with　iodine　as　the　probe.　All　values　were　lesser　than　the　corresponding　critical　micelle　concentration　(cmc(aq))　in　aqueous　solution,　where　C-12-EOx-C-12　center　dot　2Br　formed　the　normal　micelles.　The　cmc(h)　increased　with　increasing　x,　which　was　similar　to　the　variation　of　cmc(aq)　with　x.　The　saturated　amount　of　water　solubilizated　by　the　reverse　micelles　was　enhanced　by　either　increasing　x　or　by　raising　the　temperature.
